Cannot reinstall Gimp on different drive (resolved)

[EffiRain]

Hi, longtime Gimp user, 10+ years, very casually though.

The SSD where Gimp was installed recently died (Christmas). Today, I tried to install Gimp on a different drive and the installation fails. It is trying to install Gimp on the no longer existent drive, and there is no option to install it on the new drive.

Before you tell me to "uninstall the old Gimp" as per the pinned instructions on this forum, Windows uninstaller fails, of course, because the old SSD does not exist. The old SSD is dead.

Therefore, since the Gimp installer lacks such a basic function as drive selection, it appears I will need to spend time in the registry. I am not a computer genius, so yay. Great design choice.

So could someone with a bigger brain than me please explain step by step how to remove the old Gimp from the registry so that the Gimp installer can then install to the correct drive?

Thank you.

For anyone else with a similar issue, here is how my small brain resolved it:

1. Go to windows search, look for registry editor and open it.
2. Ctrl-F to "Find"
3. Search for "gimp"
4. Delete each instance of "gimp" that it finds, one at a time.
5. Close registry editor.
6. Open Gimp installer and install.

In my case, it was unable to delete those instances found in Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\bam\State\UserSettings\S-1-5-21-2307284569-1091588784-2813351028-1000 (and similar), so those were left behind. This did not seem to matter, and I was able to install Gimp to the drive of my choice.

I am not a computer tech, so use the above at your own risk. But it worked for me. How odd that the Gimp installer is not elegant enough to address reinstall situations like this, when a user does not have the option to properly uninstall prior installations of Gimp.

A bit over the top.

You are correct, it is the crumby Windows Uninstaller that does not remove registry entries.

The process is the same as installing different versions of Gimp see: https://www.gimp-forum.net/Thread-IS-the...52#pid9852

You need to look in the Windows registry for

Code:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\GIMP-2in1

and delete it. Then use the Windows Gimp installer and choose your new location.

This Did not work for me.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\GIMP-2in1
There was no "GIMP-2in1" in the Uninstall folder.
I have the same problem as OP

When I search for GIMP in the registry, as the OP suggested, the only files to appear are in 

Computer\HKEY_CLASSES_ROOT\.alpha\OpenWithProgids

and contain

(Default)
GIMP2.alpha

Should I delete these?

[rich2005]

You can delete  that, it is a file association. Lots similar to HKEY_CLASSES_ROOT\GIMP2.alpha are there.

Edit: Apologies for a typo, it is 2_is1 (at least here in a Gimp 2.10.34) Not a folder, it is a registry entry.
