hi all,

when i unpacked a file crypted with yoda's crypter after rebuilding the import tables with ImpRec it works fine on WindowsXP, but on Windows 2000 i got an error that the procedure entrypoint for "RestoreLastError" was not found in Kernel32.dll
The Packed Exe works fine on both OS.
I've fixed it and replace it with "SetLastError".

But my question is...
why is a call to a non present procedure in the unpacked exe? is this a routine in the crypter that overwrite it after loading?

ciao,

fad

Imprec puts the "RestoreLastError" call into the unpacked exe.There is a fixed exe of Imprec which puts "SetLastError" instead of "RestoreLastError" . If you want it, PM me.
