McAfee SecurityCenter Installation Error

Back story:

     - About 6 months ago McAfee stopped working after an update (again).

     - In frustration, I removed McAfee from my PC.

     - A few days ago, I attempted to reinstall McAfee.

     - First Attempt:

          * Downloaded "McAfee SecurityCenter"(DMsetup.exe) from My Account.

          * Ran executable.

          * Successful download.  Error during Installation.

     - Second Attempt:

          * Deleted DMSetup.exe.  Downloaded a new one.

          * McPreInstall:

               > Downloaded McPreInstall.exe.

               > Ran executable.

               > Received several similar error messages but also a final message about successful completion of McPreInstall.

          * Ran DMSetup executable.

          * Successful download.  Error during Installation.

     - Third attempt:

          * Defragmented.

          * Cleared out Temporary files.

          * Ran McPreInstall again.

          * Downloaded and Ran McAfee Virtual Technician.  It failed due to no installed McAfee Software.

          * Deleted and Downloaded New DMSetup.exe.

          * Ran DMSetup executable.

          * Same error.

     - Ended where I started, with no McAfee.

Operating system:

     Dell PC

     Windows Vista Home Premium

     Service Pack 1  (Please don't ask me to install service pack 2, I've been trying to for years.)

     Processor: Intel(R) Core(TM)2 Duo CPU

Error Description:

     This error occurs after the DMSetup.exe has downloaded the software, while it is trying to install the SecurityCenter.

     Message box with the contents:

          "C:\Windows\system32\regszr32.exe

          The NTVDM CPU has encountered an illegal instruction CS:124b IP:0122 OP:ffff 76 6b 0e

          Choose 'Close' to terminate the application."

     When I select 'Ignore,' the installation stalls all progress and the progress bar doesn't move for hours afterwards (or until I logoff).

     This always occurs about 1/4 the way through the installation progress.

I'm looking for help, suggestions, and solutions to this installation problem.  I appreciate any help that can be provided! Thank you!

Re: McAfee SecurityCenter Installation Error

Hello Chelsey,

To make it simple, you definitely need to install Service Pack.2 in your computer in order to complete the installation of McAfee. Please go through this KB Doc ID: TS-100410 which would clarify more about the minimum system requirements for McAfee.

Re: McAfee SecurityCenter Installation Error

Support for Vista SP1 runs out on July 12 this year so I would strongly advise you try it again.  You know that there is free Microsoft help with the installation of any service pack (or any update for that matter), but that support will only last for SP1 until that date.

More advice and help, with links to Microsoft, here:  https://community.mcafee.com/thread/2019
