I had a bit of trouble with this function in ASM, if anyone ever has to use it this seems to work OK. It is the way Microsoft recommends checking various OS version information.

This is some older code I've had laying around for quite some time, only verified for Win32 up to Win2003 and .NET 1.1. It's in C but should translate really nicely into asm. Just figured someone might be interested in a simple commandline VERSIONINFO resource editor. No need to edit resource files or recompile and link when all you want to do is change version info. Hope someone finds a use for it.
It was compiled with VC6.
It's a bit large to paste into the message. See the attachment.
