Installer Projects 2022 Extension Unrecoverable Build Error

Dave Arnold 1 Reputation point

Since upgrading Visual Studio Community 2022 to version 17.3, I am unable to build an installer project. The rest of the solution builds fine, but the installer project fails with:

Building file '...\Release\MyProjectName.msi'...
ERROR: Unrecoverable build error - 0x800700C1

It creates a .tmp file in the output directory before it fails, so I don't believe it is a permissions problem. I've tried running VS as administrator, but that doesn't help. I haven't been able to find any info on this error anywhere online.

Can anyone help with this? Thanks.

    Facing same issue a week ago.

    This error happens only ARM Windows on my environment, intel Windows runs well.
    both using VS2022 Community edition.

    VS2022 does not support officially ARM Windows machine at this time, hopefully fix this issue when official support has come on arm windows.
