Sorry for the late reply, I manually searched for these and couldn't find them. i don't even have "CurrentVersion" under Microsoft I did your second solution and it did this I have a strong feeling that it's my windows that is messed up.. I guess I'll have to do a clean install of that I'm sorry to have bothered you! If you find any other things I could try I'm up for it! Thanks a lot for your help and time!

Okay just to be sure so I don't do anything wrong here, I backed up the registry. For the first time I search for the code string, I get this Under Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MATS\WindowsInstaller\{6F0DC7EB-161A-409C-9B26-3EB3FE9ED69D} I do find next, I get Under Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Folders And I only find these two. Do I just delete them?

So I downloaded the 1.8.3 version, and this is what I got again. Then I ran this msiexec.exe /x {6F0DC7EB-161A-409C-9B26-3EB3FE9ED69D} and got this And just for good measure I'll also send you the SetupUI.log SetupUI.log This is weird right?

@Dan C Really thanks a lot for your help and @walt.farrell ! SetupUI.log

@walt.farrell I just tried now also with the 1.8.5, and it still didn't work. I went into the regedit, and there are only three options, "(default)", "No EULA", "No Update check". There isn't a designer install path. Thank you for your help

@Dan C no worries thank you for you time! Sorry to bother you this much about this. I've done everything like you said, redownloaded everything fresh, I still have the names of old Affinity folders changed (don't know if that actually changes anything) and it still give me the update button. If nothing works from this, is there an option to move the software to an other drive without having to uninstall it and reinstalling it? Because when I update, it installs it fine on the C drive. But my C drive is getting kinda full. Thanks again for your help!

Thank you, @Dan C! These are the screenshots you asked for. As you can see it's not installed or anything, the folder of the old install is still present on the drive that I want to install it to. I tried changing the name of this folder, and the name in the AppData of Affinity, to see if the installer is taking info from this, but it changed nothing. I restarted the PC after each changes that I made. Thanks again for your help!

I had a problem with Affinity Photo and Designer after a windows update, where I couldn't install new updates because for some reasons it couldn't find where I had it installed. I also couldn't uninstall it from the control panel. So I downloaded windows uninstall and install tool. It uninstalled it and everything is fine. But now when I try to install the new version, I get only one button to update Affinity designer, and it installs it on the C drive, but I don't want it to be installed there. I tried uninstalling it and reinstalling, and I always get the update button and nothing else. Any help is appreciated, thank you!
