Avisynth doesn't work with Windows 7?

[list]

After a long while i could fix the mpc win7 problem using ConvertToRGB() or ConvertToYUY2() at the end of the scripts
And other kind of problems including a copy of MSVCP71.dll and MSVCR71.dll (taked from my old windows XP x32 windows/system32) in system32 , or near the x264.exe mpc.exe or any program you use.

AVI Import Filter error: (Unknown) (80040154) - solution: A missing dll might be the problem: msvcr71.dll msvcp71.dll should be in the windows\sytem32 directory or windows\SysWOW64 (Windows 7 64Bit)

i did this and still it doesn't work
