Affected Operating Systems:

Problem

McAfee SecurityCenter fails to open, you see a blank white screen, or you see a JScript error.

Other applications on your system might have the same issue.

Cause

This issue is often caused by problems with your Windows operating system. System files depend on one another to provide full functionality. For example, if some of these components fail to register, these interdependencies do not function.

The following solutions will assist you in troubleshooting these interdependencies, assuming the problem file is part of the McAfee product. If you still see the original problem after completing the solutions, the issue is with your Windows operating system itself, and you should continue to the workaround for helpful steps to collect information for your manufacturer.

 

Solution 1

If you see a SecurityCenter blank screen, it might be caused by an incorrect registry key that references JScript.

Download and run the script that fixes this issue:

  1. Save any open work because the script prompts you to restart your computer when it completes.
  2. Download and save the script from http://download.mcafee.com/products/licensed/cust_support_patches/mcscriptfix.zip.
  3. Unzip the file you downloaded and save mcscriptfix.bat to your Desktop.
  4. Right-click mcscriptfix.bat and select Run as Administrator.
  5. Click Yes in the User Account Control box, if prompted.
    While this script runs, you see a black DOS Prompt window. 
  6. Press any key to continue when prompted.
  7. Restart your computer.

After your computer boots to Windows, open your McAfee product and verify it is functioning as expected. If you still see the original problem, continue to Solution 2.
 

Solution 2

Download and run the McAfee PreInstall Tool

  1. Download and save the McPreInstall file from http://download.mcafee.com/products/licensed/cust_support_patches/McPreInstall.exe.
  2. Double-click McPreInstall.exe.
  3. Click Start inside the Preinstall Tool.
  4. Read the warning message and click OK to agree to the changes.
  5. After the preinstall tool completes, click OK.
  6. Click Close and restart your computer.

After your computer boots to Windows, open your McAfee product and verify it is functioning as expected. If you still see the original problem, continue to Solution 3.
 

Solution 3

Uninstall and reinstall your McAfee Security product using the procedure in article TS101331.

After you finish reinstalling you have restarted Windows, open your McAfee product and verify it is functioning as expected. If you still see the original problem, continue to the following workaround.
 

Workaround

If you still cannot see SecurityCenter screens correctly after completing all of the previous solutions, you most likely have an operating system problem.

Do the following and make a note of any errors you receive.

  1. Click Start and select the Search box.
  2. Type cmd and press ENTER.
  3. Right-click command and select Open as Administrator.
  4. Type each of the following commands and press ENTER after each one:
    NOTE: After each command has run, you see a success or failure message.

    regsvr32 scrrun.dll
    regsvr32 jscript.dll
    regsvr32 vbscript.dll

    Additional command for Internet Explorer 9 users:
    regsvr32 jscript9.dll
If you received no errors during this process, open your McAfee product again and verify it is working. Otherwise, contact your manufacturer with the errors you received while performing the previous steps so they can assist you in resolving your underlying Windows problem.
