Since upgrading from 12.8 to 13.5 our core product installer fails uninstall.
The uninstall fails leaving the product orphaned where it cannot be uninstalled or installed and fouls Windows badly. The files and Programs & Features entry are not removed.
We optionally use shared folders but none were used for this installation. The uninstall exception:
MSI (s) (E0:78) [09:51:32:616]: Invoking remote custom action. DLL: C:\Windows\Installer\MSIB3F5.tmp, Entrypoint: UninstallShareFolders
Action start 9:51:32: AI_UninstallSHFolders.
CustomAction AI_UninstallSHFolders returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)
MSI (s) (E0:18) [09:51:32:616]: Note: 1: 2265 2: 3: -2147287035
Nothing has changed in the project since the 12.8 upgrade to 13.5.
I'm stuck. Will Zip the project and uninstall log and email attach to support.
