My VB copy works OK, everything but compiling. When I do so, I get the
message "wrong  version fo runtime dll ". Others 3rd party vb programs
work fine in my computer.

 I tried to reinstall it, but I got another msg that says it was
unable to register itself in someplace.

What can I do to make it work again?

Last time it occured I had to reinstall windows 95 and then VB 4  

Is there any other solution?

PS: I keep a zipped copy of the windows/system directory, does
anybodie knows the names of the runtime files to find them in that
place, and try to restore them manually?
