amazingly that test build works on nt3.51 on my fresh install haven't installed sp5 or anything, I tried standard retrozilla and firefox 2 and both gave the same errors though. "Dynamic link library MSVCRT.DLL could not be found in the specified path. C:\retrozilla; C:\WINNT35; C:\WINNT35\SYSTEM32"
also that unofficial update pack is here http://bearwindows.zcm.com.au/winnt351.htm#4
