I'm having issues with 16 on Win10 and would like to fall back to 15. But there is no Davinci or Resolve entry in the uninstall menu. How do I uninstall?

Start menu, resolve, it should give an uninstaller

If it's not showing up, try something like Total Uninstaller or JV16 Powertools. TU is good at removing completely removing all traces - files, registry entries and configurations, so you can do a clean reinstall.
And JV16 Powertools is also good at finding programs that don't show up in Windows 'Programs and Features', but also removing traces of old uninstalls left behind.

I went back to Resolve 15.3 from 16, but started having some GPU errors. TU did an awesome job of COMPLETELY removing Resolve, and no more GPU errors.

Make sure to back up your project though first! Very important.

Watch out, if you do that you might also remove and destroy the databases. Losing potentially everything.

Thanks Walter. My system also had a Win10 hard crash and required a reinstall of Windows. I had several projects that were never backed up. Where is the project information and the databases stored? Do you know if I can manually recover old projects?

Nope. No uninstaller. Of course this installed as Administrator but I am running it as a regular user. So I checked C:/users/administrator/appdata/[etc] and found links for Project Server and Resolve. No uninstaller.

Time for a super stupid question - You are using the real control panel and not the one designed for phones...right? Click Start > Type Control Panel > Enter > Find "Uninstall a program" or "Programs and Features". Self explanatory from there.

The "Settings" Program section is merely for UWP Store Apps.

I'm using the native Win10 uninstaller accessed through the control panel. First time there was an entry for Resolve Panels. I uninstalled it. There is nothing else. 16 is still installed and operating. I need to remove it.

In my version of windows there were 2 uninstallers, one for panels and one for resolve. If you can't find it under "Davinci Resolve" in the programs list, try installing the version you have again in hopes it will restore the program list. Then try to uninstall again.

I say were, because when I moved to 16 I decided to leave off the panels software since I don't have one anyway.

If that doesn't work you'll have to go to the registry to find the msi uninstall string.
Navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
Then Edit> Find
Type in Davinci Resolve and hit find
it will highlight the proper key
Double Click that key
Verify Display Name says Davinci Resolve
Double click the key that says uninstall string
Copy the data in that field
Hit Start
Type Run
Hit Enter
Paste into Run field
Hit Enter

The resolve uninstaller/modifier should now begin. Possibly preceded by a UAC prompt.

In my system the modify and uninstall strings are identical... so simply running the installer of the same version should bring up the uninstaller. I would test that theory for you but I am in the midst of a render right now.

If you can't locate the proper key, your registry got corrupted. You may be stuck with using system restore to the date you installed v16.

I encourage you to give JV16 Powertools a try. It's great at finding software that doesn't appear in Windows' 'Programs and Features, and is especially good at removing software leftovers. They offer a 60-day trial of the full version. And Total Uninstall is free and you have more control over what you're deleting (see photo). As Walter noted however, just be sure to back up your databases. Neither of the programs will touch them, but I make it a habit to do it anyway, even when updating Resolve. And it won't touch your cache, gallery, effects, media, or team projects.

Thank you Jeremy. That did it.

Now is there anyway to find the 15.3 installer? All I have is the 15.2.2 installer.

Installers as far back as version 10.1.5 are always available from:

Scroll down the "Latest Downloads" listing.

Software Update 05 Apr 2019
DaVinci Resolve 15.3.1

Thanks Renaud. I hadn't found that page with the old versions.

I too have this issue - I find it ridiculous that Davinci stores an integral file such as an MSI it knows it will need to draw on (especially considering it's a beta version likely to be updated regularly) in a TEMP folder that can be deleted.

I deleted the Resolve 16.0.0.32 installer (beta 3) so the 16.0.0.40? Installer (beta 5) can't uninstall the previous version because the uninstaller isn't there so it fails to install.

I downloaded the beta 3 installer, but now it wont extract (install) the installer (missing .msi in TEMP folder) because it thinks beta 5 is installed - which it is not, it failed, so I'm on beta 3 still..

I imagine I have to remove a registry entry somewhere, re-run the beta 3 installer, get the MSI and put it back in TEMP, run the beta 5 installer, let it uninstall the old and install the new?
Any idea which registry key I'll need to remove for this? or any other tips to resolve (haha) this?

----------------------------------------------------------------
Update.. again:
I'm very confused. I had version 16.0b.032 (beta 4, first release)
- I downloaded beta 3 and found it's v 0.28
- I downloaded beta 4 and found it 0b.033 (second iteration of beta 4, was a sneaky update)

I can't install this version, but I can't install a new version, I'm stuck without the beta 4 (first iteration) v0b.032 msi package..

If anyone can provide me with this, I think it will sort itself out during the beta 5 install / update, with all keys intact, but without that installer, I think I'm properly bonked

I accidentally installed Resolve Studio 16b7 when I wanted just Resolve. But again, the installer did *not* create an entry in the control panel so I can uninstall. The only entry created is for Davinci Resolve Panels. I'll do the manual process listed here.

Edit:
So finding the "uninstall string" in regedit and manually executing it worked again. But an uninstall link in control panel would be better.

I need to uninstall 17.1 to go back to 17.0, but 17.1 has no uninstall in Windows Control panel. So I tried the solution above, but it is still giving me an error:



Here is the Davinci Resolve Reg entry which seems to be broken I do not see the installation folder of Resolve in any of these entries. Should no entry show the installation folder?



Thanks a lot!

I've installed Resolve 16.7, a few of the betas and 17.0 - none of them has given me an uninstall link in the Start menu and none of them even gave me link to Resolve itself, just to a few tools like the Raw player, speed test, control panels, etc. I had to navigate to the Resolve executable in the "Program Files" directory tree and drag a shortcut to it onto the start menu myself.

I've always uninstalled just by going through the installed programs list, finding all the stuff that looks like it's related to Resolve and clicking "Uninstall" for each one.

I had the same problem and for me the solution was simply to login as administrator account. Even though I installed it from the non-admin user, the uninstall button was not visible in the system settings, the program folder or in third party apps as CCleaner. But changing to admin, it was there and I could easily uninstall. Still found this solution thanks to this post because someone mentioned being not the admin... So maybe this helps someone else
