I've reinstalled Windows XP 5 times in the past 2 days. Everything installs perfectly fine EXCEPT Visual Studio 6 Enterprise...which is all I really care about. I've done the reformat/reinstall procedure many times before with this exact computer setup, this exact windows cd, and this exact Visual Studio CD. I then got a friend's copy of it to try it thinking maybe it was my Visual Studio cd. Exact same error. The error occurs at the end of installation when it's updating the system and it says: vaesa.dll was unable to register itself in the system registry. autprx32.dll was unable to register itself in the system registry. NLHtml.Dll was unable to register itself in the system registry. picclp32.ocx was unable to register itself in the system registry. And then setup gives an error stating that it failed to install. What the hell is going on? I desperately need to finish a project for work and I can't install visual studio and I've tried reinstalling windows and doing windows updates with service packs and everything BEFORE installing Visual Studio and I've reinstalled windows and tried installing Visual Studio before anything else. No matter what I get the same error. Help? I'm desperate.

I have managed to install the Enterprise edition on XP home and it installs OK, can you just install VB without the rest of the programs, I understand that Visual C++ will not run with any version of XP so this may be causing the rest not to install on XP Pro. M

yeah i tried installing only vb too. i've actually successfully installed all of them on windows xp pro tons of times before (at least 4 or 5)... i don't know what it is now. could windows be installing a corrupt registry when windows is installing itself?

Hi. I know this may be a longshot, but I've seen this type of behaviour a few times, where software has worked in the past and then doesn't work properly, even with a clean install. At least twice, it has been the case where a stick of ram has gone bad. You might want to download a memory diagnostics software and run it. I use Docmem 2.0. I believe microsoft also has one of their own (a free one, believe it or not). Both of these will require you to make a boot disk. I hope this helps.

I have never had a problem with Visual C++ 6.0 on any operating system I use. At work I use it on Windows 98, Windows NT 4.0, Windows 2000 Pro, Windows 2000 Server, Windows 2000 Advanced Server, and Windows XP Professional. At home I use Visual C++ 6.0 and Visual Basic 6.0 it on Windows XP Professional.

Have you tried manually registering them before installing VS6 ? You will probably have to extract the problem files from a CAB file to C:\Windows\System32, then from a Run box type, e.g. regsvr32.exe "C:\Windows\System32\vaesa.dll", then press OK. Repeat this for each of the DLL/OCX's you are having trouble with, then install Visual Studio 6.0.
