Resolving the problem

Solution 1:

  1. Click on Start - Control Panel.

  2. Click the Java icon (for Windows 7 and Vista, Click Programs - Java Icon)

  3. On the General tab, Click Settings under Temporary Internet Files.

  4. Ensure the option delete application and applets is checked and then Click Delete Files.This step may take some time to complete.

Solution 2:

  1. Use a 32-bit browser (e.g., IE - installed in C:\Program Files (x86)\Internet Explorer) which has a 32-bit JRE version enabled on it. Alternatively, a 64-bit browser with a 64-bit JRE enabled on it.

    Here is a helpful document with details on Java enablement on browsers.

  2. Update JRE to a later version and check if the issue persists.
