Trying to uninstall Quicken on Windows 11. In Settings→Apps→Quicken→Uninstall, security warning then pops up to grant access to 1945a5.msi to make changes to the Windows. Is this a legitimate installer package for Quicken?
I couldn't find a file by that name on my Win10 PC. Where is the file located? Some things you could try…
Scan the file with your anti-virus program.
Peek inside the file with 7-zip and see if anything looks suspicious.
