The 25002 error is a problem which will normally occur when you either try and install / uninstall Norton or Alcohol on your PC.

Here’s how to fix the problem for good:

What Causes The 25002 Error?

This error is basically going to be caused by the way in which Windows cannot process the files & settings it requires to run properly. The error will typically show in this format:

Error 25002: Failed to load navinsnt.dll.

The causes of this problem are basically going to be down to the way in which your PC will not be able to read the files or settings required for the installation to commence. The problems include the likes of your user account not having the correct permissions to run the file, as well as having a series of different issues with the “registry” of your system, etc.

How To Fix The 25002 Error On Your PC

Step 1 – Make Sure You Have The Correct Permissions On Your System

The first step to resolve the 25002 error is to make sure that you have the correct permissions on your system. Many people use a series of different user profiles on their PC, and it’s often the case that your system will not have the correct permissions required to install the software on your PC.

The bottom line is that if you aren’t logged on as an administrative user, log out and then log in again with a user account that has the required rights.

Step 2 – Fix The Navins95.dll & Navinstnt.dll

It’s often the case that the NavInst95.dll or Navinstnt.dll file will be damaged or corrupted on your system. If this is the case, then you need to make sure that you are able to repair any of the problems which are leading the errors to form – a process that can be fixed by using the steps outlined here:

  • Click “Start” and select “Search”
  • Search for the following files:
    – Navins95.dll
    – Navinstnt.dll
  • When you locate these files, you should rename them to “navinsnt.dll”

Step 3 – Fix Any Corrupt Registry Settings

Another cause of the 25002 error is that there will be some corrupted & unreliable settings inside your computer. These settings are stored inside the “registry” database, and are used to determine how your computer is able to correctly install a program onto your system. You can fix these registry errors here:

  1. Click Start, select Run
  2. In the box that shows, type regedit, and then click OK
  3. In the Registry Editor window, navigate to the following registry key:
  4. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Contr ol\FileSystem

  5. Double-click NtfsDisable8Dot3NameCreation in the right-pane.
  6. Next, change the data in the Value data field from 1 to 0.
  7. Exit RegEdit and then restart your PC.
  8. Install Symantec AntiVirus Corporate Edition client on your computer.
  9. After the installation is complete, change the value ofNtfsDisable8Dot3NameCreation back to 1.

The “registry” is also a huge cause of the 25002 error on your PC.

Continually being used to help your computer run as smoothly as possible, the registry is responsible for everything from storing your desktop wallpaper to your emails.
