Hi
Have 2 PC one running Windows 11 Mailspring installed with no problems but installing it on the Windows 10 PC fails. Any idea’s as to a work around?

The SquirrelSetup.log from this failure says Windows refused to run mailspring.exe because “the specified executable is not a valid application for this OS platform”. That’s the error you get when a 64-bit program is launched on a 32-bit copy of Windows, and the Windows build of Mailspring has been 64-bit only since the 1.10 releases in 2022. That would also explain why the same installer works on your Windows 11 PC and not this one.
You can check under Settings > System > About > “System type”. If it says 32-bit operating system, there’s unfortunately no build of Mailspring that will run on it, and the only fix is a 64-bit Windows install. If it says 64-bit and you’re still seeing this, please open a new topic with the log and I’ll dig in.
