White screen for McAfee LiveSafe

[ATD]

Hi

When I try to open McAfee LiveSafe, it opens a white window (sometimes with the McAfee logo) and then nothing happens.  I can not get to any of the options - eg, I can not switch on/off VPN.  I can run a scan from the system tray icon, but can not do anything else.

I have the latest version of LiveSafe (1.11.279.1) installed on a Windows 10 Home 22H2 desktop.

I have tried uninstalling and reinstalling the software several times and have also uninstalled using the Removal Tool and downloaded a new copy of the McAfee installation file.  I have reinstalled Windows 10 (using the latest download available from Microsoft) and sfc and DISM both show no issues.

I have seen that this issue happened to others about 10 years ago but can not find anything more recent than that and solutions offered at that time seem to be no longer applicable.

Can anyone suggest what I can do about this?

Thanks

Hi

Update: I have now managed to find a solution to the issue:

TLS 1.2 had somehow become disabled.  Going to Control Panel, Internet Options, Advanced tab and selecting Use TLS 1.2 in the Security section seems to have resolved the issue.

Whether or not this resolves this for others, I can not say.  But, I can now see the normal McAfee screen with all of the options and can, for example, switch VPN on/off again.

I found this when trying to update the Vivaldi browser - without TLS 1.2, no update is possible.

Hi @ATD,

Greetings from McAfee. 
We apologize for the inconvenience. 

McAfee Security Center fails to open or opens to a blank white screen, or you see a Java error. Other applications on your system might have the same issue. Make sure your OS is upto date. 

Cause

This issue is often caused by problems with your Windows operating system. System files depend on one another to provide full functionality. If some of these components fail to register, for example, these interdependencies will fail to function.

Solution 1

If McAfee SecurityCenter displays a blank screen, it might be caused by an incorrect registry key that references jscript. Perform the following steps to download and run the script that fixes this.

1. Save any work. The script will ask you to reboot your computer when it completes.
2. Click the following link and save the file to your desktop:
      
       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, a black DOS Prompt window will open on your screen.
6. When you are prompted to Press any key to continue in the DOS Prompt window, click inside the window and press any key.
7. Restart your computer.

Solution 2

Restarting your computer frequently resolves these types of issues, but deeper troubleshooting might be required. Perform each of the following solutions in order, then verify the issue is resolved. If your issue is resolved, you can stop there. If your issue persists, continue to the next solution.


Verify Java is installed and up-to-date

1. Close any open applications and restart your computer.
2. Click Start and select the Search box.
3. Type Programs and Features.
4. Open Programs and Features.
5. Locate Java in the list of installed programs.
      
      
   • If Java is listed, click Start and select the Search box.
   • If Java is not present, install it from http://www.java.com.
   • If you find multiple versions of Java installed, remove all versions, restart your computer, then install Java again.
      
6. Type Control Panel.
7. Double-click the Java icon.
8. Click the Update tab.
9. Click Update Now.

If the update tells you that you have the most current version, close the Java control panel and proceed to the next solution. If the update runs, restart your computer and try opening SecurityCenter again. If you still cannot view the SecurityCenter, proceed to the next solution.

Solution 3

Download and run the McAfee PreInstall Tool

1. Go to  http://download.mcafee.com/products/licensed/cust_support_patches/McPreInstall.exe, and save the McPreInstall file to your desktop.
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.

Open SecurityCenter. If you are still unable to see the SecurityCenter screens, continue to the next solution .

Solution 4

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

Solution 5

If you still cannot see SecurityCenter screens correctly after completing all of the previous solutions you might have an operating system problem. Perform the following steps and make a note of any errors you receive.

1. Click Start and select the Search box.
2. Type the following command and press ENTER:
      
       cmd
       
3. Right-click command and select Open as Administrator.
4. Type each of the following commands and press ENTER after each one. After each command has run, you will see a success or failure message:
      
      
   • regsvr32 scrrun.dll
   • regsvr32 jscript.dll
   • regsvr32 vbscript.dll
            
            
   • Additional for Internet Explorer 9 Users:
            
             regsvr32 jscript9.dll
     
      

Open Security Center again.  If you still cannot see the SecurityCenter screens, contact McAfee Technical Support or your computer manufacturer with these errors for additional assistance.

Regards,
Abhi

While it is obviously a bit late to mention this, but never ever install any McAfee products on your PC. McAfee is malware. You might want to install McAfee on your enemy's PC, if he's your mortal enemy.

But even then, that might be considered cruel and unusual.
