On Windows, you have to manually uninstall Resolve if you are trying to install an older or same version.

What version of Resolve WAS installed, and what version are you trying to install?

At any rate, if you go to the Windows Programs and Features control panel, is DaVinci Resolve in the list?

If it is, right click it and select Uninstall.

Then try installing again.

Start PowerShell (Admin) and run next command:
Code: Select all
REG DELETE "HKLM\SOFTWARE\Blackmagic Design" /f

Then start installer (don't need uninstall now).

was an early version of 14...was slightly buggy with keyboard shortcuts as i remember. trying to install latest free version. i think i uninstalled it previously but somehow it had some trailing files. maybe was not installed on C? cant remember. some kind of global regedit to destroy all traces would be nice

Verify again that DaVinci Resolve is not in the Control Panel - Programs and Features area. If it is, right click and select Uninstall.

Check for this folder: C:\Program Files\Blackmagic Design\DaVinci Resolve

Does it exist? If so, delete it, and try running the Resolve 14.3 installer again.

What this will do, is delete the software registry entries for ALL Blackmagic Design apps you have installed, not just Resolve.

I would call this very unsafe behavior.

Also, you must ensure the C:\Program Files\Blackmagic Design\DaVinci Resolve folder is gone before doing a new install. Failure to do that could lead to bad things.

What I would suggest, if you are in a scenario where Resolve won't install, is to use the Windows Control Panel - Programs and Features panel to remove Resolve. If you don't see Resolve in that list, and it won't install, then delete the folder mentioned above, then run regedit and go to:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Blackmagic Design\DaVinci Resolve

In the right hand window, double click Version, and in the Edit String window that opens, delete the existing Value Data, and click OK. Then exit regedit.

Now run the Resolve installer, and it should install Resolve.

Dwaine, FYI I struck this issue again today installing my new Resolve Studio 16 (delivered today) and had to do all of Control Panel uninstalls, finding Resolve still in C Program etc and then the Reg Edit thingy... then the Resolve Studio 16 install worked fine...it had been finding a newer version still installed...

This solved it for me, pretty amazing tool.
The problem started when doing routine cleanup of my system my antivirus searched through the Temp directory and found the Resolve uninstaller and I didn't notice and removed with all the others, I would suggest putting it under the Resolve application directory to avoid this in the future, it really is frustrating.
