I use McAfee's Site Advisor (Pro.)
I've been trying to install an update via IE7.
I have no problems downloading it.
However, each time I try to install, I get "Microsoft Visual C++ Runtime Error" message. It continues, "This application has requested the Runtime to terminate in an unusual way. Please contact your administrator......."
I've cleaned and defragged memory, but still no luck.
Any advice would be greatly appreciated.
Thank you.

Hello and Welcome to TSF

You are experiencing this because of one of these 4 reasons:

1. Confliction with TSR or other running program
2. Software issue
3. Computer Virus
4. Memory issue

Do you have any toolbars installed? (Google, Yahoo....ect)

Confliction with TSR or other running program

If you are encountering a runtime error message while in Windows or above ensure that the issue is not being caused by a third party program or TSR by end tasking all open programs. Additional information about TSRs and how to end task a TSR can be found on document CHTSR.

If, after end tasking all TSRs, you continue to experience the same issue and are running Windows 95 or Windows 98, verify that no utility or program is being loaded in the autoexec.bat / config.sys that is causing your issue by temporally renaming the files. To do this, follow the below instructions.

1. Boot to a MS-DOS prompt. Information on how to do this can be found on document CHDOS
2. Once at the MS-DOS prompt, type:

cd\ <press enter>
ren autoexec.bat <press enter>
ren config.sys <press enter>

Once completed, reboot the computer.

Software issue

If your issue persists it is possible that the program, utility or game causing the runtime error may have issues. Verify through the developer's web site that all updates or patches that may be available have been downloaded and applied.

If no patches or updates are available, attempt to uninstall and/or reinstall the program that is causing the issue. If you are having a runtime error in your operating system, reinstall the operating system.

Computer virus

Because computer viruses are capable of tampering with the system settings / memory it is possible for a computer virus to generate a runtime error. If you are currently running a virus protection program on your computer ensure it has the latest updated patch or .dat file.

If you do not have a computer virus protection program it is recommended one be purchased or that a demo be temporarily downloaded to scan your computer hard disk drive for viruses.

Additional information about computer viruses can be found on our virus information page.

Memory issue

Finally, if you have followed all of the above recommendations, it is possible that you may be encountering a hardware / memory related issue. We recommend that you first contact the developer of the program causing the issue for any possible solutions. If no solutions are found, we recommend you contact the computer or motherboard manufacturer for additional recommendations and/or service.
