How To Fix MsJava.dll Errors

MsJava.dll is associated with Java Virtual Machine. Internet Explorer and websites make extensive use of Java, so the MsJava.dll error is mostly, although not exclusively, associated with the use of the Internet. Unfortunately, msjava.dll errors appear if the version of Java installed is corrupt or damaged. When the user attempts to install Internet Explorer or make use of it, MsJava.dll may display an error and the process cannot proceed. Following this method should correct this problem.

What Causes MsJava.dll Errors?

If you have issues with MsJava.dll, your PC may display an error message similar to this one:

IE5WZD caused an exception C0010000H in module MSJAVA.DLL

These errors are related to Java Virtual Machine. It is likely to be damaged so cannot load and causes this error to be displayed. To resolve this, follow the steps below.

How To Fix MsJava.dll Errors

Step 1 – Restart your PC in MS DOS mode

  1. Click Start > Shut Down > Restart in MS-DOS mode
  2. Type these instructions, making sure to press ENTER after each command line
    cd windows\system

Sometimes during updates, the DLL files fail to register. These can easily be registered by following these steps:

  1. Click Start > Run

  • regsvr32 urlmon.dll

Restarting Internet Explorer, the problem should now be eradicated. However, in the exception that the problem may still be present, carry on to step 3.

Step 4 Clean Out Viruses

Antivirus programs are software tools which scan through your PC and remove any of the viruses or malware infections that are on your system. It’s often the case that viruses will infect various DLL files on your computer and then cause them to be unreadable to your PC. To ensure this is not happening on your computer, you should try using an antivirus program to scan through your system and remove any of the infections that cause all these errors. You can download our recommended antivirus program from the link above, but there are a large variety of programs available.

Step 5 – Clean Out The Registry

It’s often the case that registry errors cause the msjava.dll error to appear. The “registry” is a central database which stores all the settings, information and options for your computer, and is where Windows keeps a LOT of vital settings that it requires to run. It’s often the case that a lot of registry settings become damaged and corrupted, leading your PC to take longer to run, making it run slower and with a lot of errors. To fix this problem, you should use a ‘registry cleaner’ to scan through your PC and fix any of the damaged or corrupt settings that are inside it.
