ClickOnce uninstall on ARM fails

Occasional Visitor

Visual Studio 2019 built & published a ClickOnce installer. The app successfully installed and ran on on an Intel platform running Windows 11 Pro Insider Preview Build 22526 rs_prerelease.211215-1332. After running the installation and test, uninstalling via appwiz.cpl successfully uninstalled the app.

 

Running the ClickOnce install on an ARM64 Surface Pro X running Windows 11 Pro Insider Preview Build  Build 22526 rs_prerelease.211215-1332 raised the nastygram:

RunDLL
There was a problem starting dfshim.dll
dfshim.dll is not a valid Win32 application.
