Uninstaller (current user) does not work

[jzpt]

Running syncthing 1.27.4, I cannot uninstall: after starting it up, uninstaller keeps hanging on 0%

Task Manager shows nothings happening either

[Bill-Stewart]

Sorry, I am not able to reproduce this. I would recommend starting the uninstaller with the /LOG parameter and check the content of the uninstaller log. Example:

C:\Users\username\AppData\Local\Programs\Syncthing\uninstall\unins000.exe /LOG=C:\Users\username\Documents\uninstall.log

[jzpt]

this is what came out of the log:

[Bill-Stewart]

The next step after running stctl.exe is to remove the Syncthing firewall rule, which will provoke a UAC prompt if the uninstaller is not elevated. Please try removing the firewall rule manually before performing the uninstall with logging:

[Bill-Stewart]

You can also check whether the firewall script hangs. Sample command:

C:\Windows\system32\cscript.exe "C:\Users\username\AppData\Local\Programs\Syncthing\SyncthingFirewallRule.js" /test

[jzpt]

I've entered the test command and it seems to hang

[Bill-Stewart]

Naturally, there's the problem. Perhaps you have an anti-malware program or something similar that's interfering with the WSH host. As I said, I can't reproduce it.

[jzpt]

I exited the malware-program, temporarily disabled the firewall, and the uninstaller still hangs

[Bill-Stewart]

Does this happen only on a single computer or on more than one computer?

[jzpt]

I only use SyncThing on my Windows desktop and Steam Deck, and my installation is different on the latter.

[Bill-Stewart]

There's something blocking cscript.exe and/or wscript.exe from running, possibly. I don't know what that could be, as I can't reproduce it. Once you fix that problem (whatever it is), you should be good to go.

[jzpt]

Any way to bypass whatever it is cscript and wscript are supposed to do or to just uninstall the program manually. I am not good at this, I have tried everything I can personally thing of and it just doesn't work.

[Bill-Stewart]

The uninstall consists of removing the Windows Firewall rule, the scheduled task (if you installed it), and the installation directory.

[jzpt]

I've checked the Windows Firewall with Advanced Security console and I can't find a Syncthing rule there and I don't seem to have a scheduled task, so if I deleted the installation directory I should be good?

[Bill-Stewart]

Yes
