The registry is another big cause of the 800A0046 error.  This section in your computer is essential to the operation of your PC since all hardware and software applications use the processing information stored here.  Unfortunately, a lot of the files that are kept here are also useless.  This is due to several reasons, such as programs leaving leftover files in the registry after you have uninstalled them from your PC.

Another reason will be cookies that place worthless extension settings in this sector of your system.  Collectively these useless extension settings serve to just slow your PC down, causing crashes to occur and errors to surface.  This is the reason why you need to periodically clean your registry.  However, it is not recommended that you do this on your own as some important files may be accidentally deleted in the process.  For this reason, it is advisable that you use an automated registry cleaner for this purpose.

What Causes Error 1618?

This error will show as:

ERROR_INSTALL_ALREADY_RUNNING.

which may be followed by

Error 1618: Another installation is already in progress. Complete that installation before proceeding with this install.

This will arise when Windows Installer has more than one instance running. Solving this problem is quite simple, you will either have to end the other Windows Installer process or if the problem does not subside then carry out a registry scan with a recommended registry cleaner.

How To Fix Error Code 1618

Step 1 – Make Sure You Only Have One Instance Of Windows Installer Running

Having multiple Windows Installer processes can cause the application itself to get confused. Two Windows Installer procedures cannot be run at the same time, it has not been designed for that. If you are receiving the 1618 error message, you must close all other installation programs down. These may be in the task bar or, if there is a setup running in the background, in task manager. Always look out for any unusual processes or processes with names like “setup.msi” or “setup.exe” as these are the likely ones to be causing this conflict.

Preventing dual installers from loading up is also vital to maintain the integrity of your system.

To prevent a second instance of the Windows Installer, do not repackage a Windows Installer package into another Windows Installer package such as a custom .msi file. Office updating and upgrading will not work with nested installations with the current version of the Windows Installer.

All Office public updates include a bootstrapping program that is named OHotfix. While OHotfix is not the only tool that you can use to deploy updates, it is the easiest to use because it provides a lot of the necessary updating functionality.

You can also use other updating bootstrapping programs, such as a simple batch file or a complex custom program that uses the Windows Installer API calls.

A nested installation shares the same user interface and logging settings as the main installation. Developers should note the following warnings when authoring nested installations:

• Updating and upgrading may not work with nested installations.
• The Windows Installer may not correctly cost a nested installation.
• Nested installations cannot share components:
  • An administrative installation cannot also contain a nested installation.
  • Integrated ProgressBars cannot be used with nested installations.
  • Resources that are to be advertised cannot be installed by the nested installation.

Making sure that these routines are carried out correctly should asatain whether you will receive this error. This error is not that hard to avoid but does require a certain level of knowledge. However, if the above did not provide the solution, you must carry on to the next step and use a “registry cleaner”.

Step 2 – Use A Registry Cleaner

Another way to fix this error is to use a ‘registry cleaner’ application to repair the various damaged settings the right might have. The registry is a database inside the Windows system which stores important settings & options for your PC. Unfortunately, this database is continually being damaged, preventing Windows installer from being able to use it correctly. To fix this problem, it’s highly recommended you use a “registry cleaner” program to fix any of the damaged settings that are inside this database. Not many people realize it, but this could be the reason why the 1618 error is appearing.

What Causes The 1619 Error?

You may receive this error when attempting to install a program:

This installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer package.

This message is explaining that there has been an error and it is the fault of Windows Installer, there is something wrong with the version you have installed on your PC. There are a few solutions to these, you could update Windows Installer as having older versions may not be compatible with the newer installation methods or you could update Windows itself, as this will provide you with a numerous hotfixes that deal with Windows Installer problems.

How To Fix The 1619 Error

Step 1 - Update Windows Installer

Microsoft are continually updating Windows Installer to meet the demands of the increasingly demanding software. You can downlaod updates to Windows Installer here. Updating Windows Installer will allow it to communicate with newer software packages, meaning that errors, such as error 1619, could be eradicated from your system.

Step 2 - Update Windows

Also, you should make sure Windows is completely updated itself. Windows Installer uses many components so having a completely updated Windows operating system will update these components as well. Microsoft have released many hotfixes and patches for various parts of Windows Installer, if you update to the latest service pack and maintain a good level of system updates, it should provide your system with the ability to deal with new software and allow it to install and uninstall various software packages, preventing the 1619 error.

Step 3 - Clean Out The Registry

The ‘registry’ is one of the causes of the 1619 error, and is continually making your PC run slowly & with errors as a result. The registry is a big database inside the Windows system, which stores vital settings, options and information for your computer. It’s where your system & all your software stored settings that your computer requires to run. The problem is that Windows often uses this database so much that it saves many parts of it in the wrong way, causing it to become damaged & corrupted. To ensure this is not a problem, it’s recommended you use a ‘registry cleaner’ program to scan through your PC and repair the various errors that could be causing a problem.

What Causes Error 1328?

The 1328 error is typically caused by a mis-match or misunderstanding between two elements of the Windows Update feature and the Microsoft Office updater that is updated when you install XP SP1 onto your system.

The error message you typically see is this:

“Error 1328. Error applying patch to file <admin image path>\SETUP.EXE"

The causes of the error are as follows:

• Your installation of Office requires administrative privileges in order to change / update any part of it.
• Registry errors
• Virus infections
• You are trying to install the SP1 update on a network computer which requires administrative privileges.

How To Resolve The 1328 Error

Step 1 - If You Clicked “Ignore” On The Error Message

If you allowed  the update of your administrative installation to continue by clicking Ignore to the error message, follow these steps:

1. Rename the existing copy of Setup.exe on your administrative installation to EnhSetup.exe.
2. Download the Setupsr1.exe file from the following Microsoft website:
   http://www.microsoft.com/downloads/details.aspx?FamilyID=10b5
3. Double click the Setupsr1.exe to extract the Setup.exe file. The default folder to extract this file to is C:\Program Files\ORKTools\Download\Tools\Setup.
4. Copy Setup.exe from this folder to your administrative installation.
5. Apply the SR-1 Administrator Update to your administrative installation again.

Step 2 - If You Clicked “Cancel” On The Error Message

If you stopped the update of your administrative installation by clicking Cancel to the error message, or if you did not apply the SR-1 Administrative Update, follow these steps:

1. Check the version of Setup.exe on your administrative installation.
2. If the version of Setup.exe is 9.0.2720, rename Setup.exe to EnhSetup.exe. If the version of Setup.exe is 9.0.2611, skip to step 4.
3. Copy the Setup.exe from your Office CD to your administrative installation.
4. Apply the SR-1 Administrative Update to your Office 2000 administrative installation.

Step 3 - Clean Out Any Viruses On Your PC

• Download This Antivirus Program

Viruses can cause the 1328 error to appear if they infect the various parts of your system which are required to process the update. One of the biggest problems for XP computers is the way in which viruses often latch onto various files & programs; and end up corrupting them. This causes updates, such as the one you’re installing, to become unreliable and stop working. To make sure this is not a problem, you should try and use an antivirus program such as XoftSpy to remove any viruses from your system.

Step 4 - Clean Out The Registry

• Download This registry cleaner

The “registry” of Windows is also a big cause of problems for your computer – as it’s continually becoming damaged and corrupted. The registry is a central database which stores vital files and settings that your system requires to run, and is what Windows uses every day to help it run as smoothly as possible. Unfortunately, the ‘registry’ is also constantly being saved in the wrong way, causing your computer to slow down and suffer from a series of errors that cause it to run unreliably. To fix this problem, it’s highly recommended you use a ‘registry cleaner’ to fix any of the damaged registry settings that are inside your PC, allowing your computer to run as smoothly as possible again. You can see our recommended registry cleaner below:

What Is The 1603 Error & What Causes It?

• “Error 1603: A fatal error occurred during installation”

The 1603 error is typically shown when you try and install or use the Windows Installer software. This error normally occurs either because you are trying to install the software into an encrypted folder, the drive which you are trying to install this software on is used as a substitute on your system or the Windows installer uses the “system” account to install the software… and if this account does not have administrative privileges, then it will show the error.

You can fix the 1603 error by following the steps below:

How To Fix The 1603 Error

Step 1 – Install The Package In A Folder That’s Not Encrypted

If you are trying to install the Windows Installer package into an encrypted folder, then you need to be sure that you’re able to install the program into a folder that is not encrypted. To do this, you need to be sure that you have a folder that’s not encrypted and then install the program into there.

Step 2 – Ensure The Installation Drive Is Not A “Substitute Drive”

A “substitute drive” is another term for a “virtual drive” and any installations to this drive will cause Windows to be unable to read the files it needs to install, causing the 1603 error. In order to make sure that this is not a problem, you should ensure that you are not trying to install your Windows Installer program to one of these substitute drives.

Step 3 – Change The “SYSTEM” Account Settings On Your System

If you receive the error message because the SYSTEM account does not have Full Control permissions on the folder that you try to install the Windows Installer package to, then you should use the following steps:

1. On the Windows desktop, double-click My Computer. The My Computer window appears.
2. Right-click the drive that you want to install the Windows Installer package to, and then click Properties.
3. Click the Security tab.
4. On the Security tab, do the following:
   >> If you are using Microsoft Windows 2000, verify that the Name box contains the SYSTEM user account.
   >> If you are using Microsoft Windows XP, verify that the Group or user names box contains the SYSTEM user account.
5. If the SYSTEM user account does not appear in the box, follow these steps to add the SYSTEM account to the box:
   1. Click Add. The Select Users or Groups dialog box appears.
   2. In the Name field, click SYSTEM, and then click Add.
   3. Click OK.
6. In the Permissions section, click to select the Full Control check box underAllow, and then click Advanced.
7. Do the following:

• • If you are using Windows XP, in the dialog box that appears, click to select the Replace permission entries on all child objects with entries shown here that apply to child objects check box for the SYSTEM account, and then click OK.
  • If you are not using Windows XP, in the dialog box that appears, click to select the Reset permissions on all child objects and enable propagation of inheritable permissions check box for the SYSTEM account, and then click OK.

8. Run the Windows Installer package again

These steps should fix the 1603 error on your PC. We also recommend using a “registry cleaner” to prevent further errors:
