pkgmgr being invoked from 32-bit instead of 64-bit

setup.exe file was created using the Installshield 2010. When this setup.exe for AMD64 is being invoked, the LaunchExe invokes the 32bit pkgmgr instead of 64-bit pkgmgr.

when I had made changes to be SW_SHOWNORMAL, the directory was set to c:\windows\syswow64 instead of c:\windows\system32.

Since its a 64-bit machine, the setup.exe is supposed to launch the executables from c:\windows\system32, but that doesn't happen. The installation folders seems to be correct, they are created under "c:\program files" but not under "c:\program files(x86)".

The installshield project is a basic MSI. The current problem was noticed in windows 2008 R2. This same setup.exe file was successful in windows 2003.

To be precise, invoking pkgmgr.exe inside a custom action in windows 2008 R2 invokes 32-bit pkgmgr.

Please tell me what the problem could be.

Thank you.

what does your custom action look like? Is it just an exe or vbscript? Also, how about specifying the full path to the exe using [System64Folder]?

If you are calling pkgmgr yourself from a script custom action do what I've found necessary which is to have 2 copies of the custom action, one marked to use 64bit scripting and the other not. Set conditions based on VersionNT64.

I have this same problem though with ISIISInstall running on a 64bit 2008 system: it calls pkgmgr (maybe through aspnet_regiis) from the syswow folder which therefore throws an error and doesn't install asp.net.

I tried providing the full path system64folder, still the pkgmgr or dism redirects to the 32-bit dism or pkgmgr.

But now when i gave the path as c:\windows\sysnative\dism.exe solved the issue.

sysnative is supposed to be the virtual directory and can redirect to current running OS bit-level.

I would have to try the other option given by manicfiddler.

Thanks
