Ok, I did that, I even put the DLL in the same folder as the app, and wrote the BAT like this

regsvr32.exe msvbvm60.dll
Autorun.exe
exit

First it says "File Not Found" on the first line (even though msvbvm60.dll is in the same folder as Autorun.bat is) then the DOS window does not close automatically.

So now what?
