32-bit build regression: System.AggregateException The specified executable is not a valid application for this OS platform

[Thomas101]

Operating System Windows 10. 32-bit only

Version: 2.6.0, 2.6.1, 2.6.2, 2.6.3. Does not affect 2.5.2 & earlier

When using electronInstaller.createWindowsInstaller() I've started seeing the error below. This only affects 32 bit versions of windows. After downgrading the to 2.5.2 it starts working again.

Error: Failed with exit code: 4294967295

+1 Win7 32 bits here

I have that same problem. OS: Windows 7 32bit only Windows-installer version: 2.6.3

[Manishbatra4]

any solution?

[abdurrahmanekr]

I think I solved the problem by adding --arch=ia32 to electron-packager.

electron-packager . App --platform=win32 --arch=ia32

+1, using --arch=ia32 and still seeing this issue Win10 32 bits

[cfinn0510]

We were actually still installing the 64 bit version. Using electron-packager and --arch=ia32 works for us on a 32 bit Windows 10 VM.

@abdurrahmanekr @cfinn0510 the issue you're seeing is with electron-packager not this repository windows-installer.

The issue still occurs in 2.6.4

Could it be related to this: https://github.com/Squirrel/Squirrel.Windows/issues/1148#issuecomment-328932091?

From same issue (https://github.com/Squirrel/Squirrel.Windows/issues/1148#issuecomment-354074569):

lukywong:

paulcbetts is it possible to support 32-bit version of windows? because i really want it support

anaisbetts:

lukywong No, sorry! While the installer you build will support 32-bit computers (i.e. your users can have 32-bit OS), your computer must be 64-bit.

Guessing this issue can be closed.
