Based on the screenshot and the behavior you're seeing, it seems like the Windows Installer registration for Resolve has become corrupted, and Windows is trying to locate the original ResolveInstaller.msi file that it no longer has access to. Since you've already tried all the common uninstalling and testing steps, consider:
- Download and run Microsoft's Program Install and Uninstall Troubleshooter
- Choose Uninstalling > if you see any entries related to Resolve, remove > Restart PC.
- If you don't, press Win + S > search and open Command Prompt (Run as Administrator)
- Run
wmic product get name> look for the exact product name for Resolve and note it down - Run
wmic product where name="REPLACE THE NAME HERE" call uninstall> restart and test it again.
Unfortunately, until the broken installer registration is removed, Windows will continue to block any clean reinstall attempt. If the issue persists, consider sharing your Windows version. It'd be helpful to look for the most suitable solution.
