I could use some help dealing with these error messages I get when I boot up my computer and when I try installing/uninstalling programs. The usual message I receive when trying to install programs such as AVG tend to be something like this,w ith a big black command window popping up: 16 bit MS-DOS Subsystem C:\WINNT\system32\drwtsn32.exe The NTVDM CPU has encountered an illegal instruction. CS:0563 IP:0116 OP:63 05 c8 53 ee Also happens with install shield as well, getting an error message: Error Code: -5011 : 0x80040707 So they all must be linked. I've tried several virus scans over and over and nothing has seemed to pick up. I have a hijack this log to post at the ready if need be, I could just really use some help..I can't install anything!

Please post your Hijack This log.

The Hijack This log looks clean, all the info if find points to a rare install shield problem. AVG antivirus may not installable any longer as it will be discontinued as of JAN 15, 2007 but I think the AVG antispyware is usable. If you want to see a suggested fix and if you are comfortable editing the registry look at this link, scroll down to the xp/2000 suggestion: http://consumer.installshield.com/kb.asp?id=Q108167

I looked and followed the instructions on the installshield site, and everything looked fine, nothing still hasn't been solved. Thanks for the help, though. I really don't want to resort to reinstalling Windows as I don't want to lose most of my files and programs.

See if this link at Microsoft may help you "I hope my Suggestions Helped"

Those error codes look like a failing memory stick. Larry Sometimes I think I understand everything, then I regain consciousness
