So I've got this program which a setup is designed for x32 systems and the other for x64. Do I need to create a program for that or can I simply make the Autorun.inf recognize which one should be installed? Or do I need to create a batch file for that?

Obs.: The program is separated in 2 folders. I.e. Program (x32) and Program (x64).

  • If you want to automatically start your application then you need a launcher program which uses logic to determine which version of the executable to start.

  • @Ramhound, I see. I'd do that if I knew some programming, but I think I'll pass. But thanks for the notice. Maybe C++ or something?

  • I took this question as you were the author of a program with two versions and you wanted to automatically run the correct program when the disk was ran. If you are not the author of the program, then the author has to offer this functionality, so your question is not clear given this no revelation.

  • You can make an auto run file that will open the batch file as a silent window that will check if you are running a 32 bit or 64 bit version.

No, it is impossible to do so with an AUTORUN.INF file. According to https://msdn.microsoft.com/en-us/library/aa969327.aspx , there is no command to do this. You will have to do this with a batch file.

You can do this (not tested though so don't scream at me)

wmic os get osarchitecture >tmp.txt
Findstr "32" tmp.txt
if  errorlevel 1 (start 32bit.exe & exit)
Goto 2
wmix os get osarchitecture >tmp.txt
Finstr "64" tmp.txt
If errorlevel 1 (start 64bit.exe & exit)
  • Sorry I can't format this a s code, I'm on a phone AND it is impossible.
