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

**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.

```
