Unable to uninstall 3cx Desktop App

[russnat8]

Hello,

I've been trying to uninstall the 3cx desktop app from my machine, but it appears that the MSI to do so is gone and despite my best efforts I cannot locate it, or find a download location to get it again.
It looks like according to the Windows Add/Remove programs my app was updated to 18.12.422 yesterday, but when I try to uninstall it, it's looking for the 18.8.508 MSI.

Anyone have any suggestions on where to go from here?

Hello,

Try this method to remove it entirely via script: https://www.3cx.com/blog/news/uninstalling-the-desktop-app/

The problem is that it keeps looking for the old MSI

Hello,

Can you please try to download the new version we just released, and right click the MSI and select uninstall first?

Please let me know if this method worked for you.

This action is only for products installed
I am in an endless loop of I cant install and I cant uninstall because the system shows I have version 416 still installed and when I try to remove version 18.12.416 it says is not a valid installation package

1. Run the new installer and complete the install (so it can overwrite everything)
2. Then uninstall it
3. Go to %appdata%\3CXDesktopApp and you can empty this folder of anything remaining
4. Now would be a good time to run your virus scan if you want to ensure everything is clean

After this is done, you can install the new app again and provision it as you normally would.

Step 1 Fails. As I am installing it refers back to the 3CXDesktopApp-18.12.416.msi, I am using 3CXDesktopApp-18.12.245.msi that I downloaded.

Not sure if this "trick" will work, but worth a try

- Make a copy of the new installer and give it the same name as the old one.

- Then point the dialog box to the path where the this installer sits and see if it will accept it.

that fails

That fails it complains that the msi is not valid

 

[JohnS_3CX]

Ok I purged my installer and got the same error as you.

Then I ran this tool from Microsoft: https://support.microsoft.com/en-us...-removed-cca7d1b6-65a9-3d98-426b-e9f927e1eb4d

Thank you that did clear up the issue

 

[JohnS_3CX]

Excellent! We still recommend to use the PWA app for the moment instead of the desktop app, so avoid using the new app for now unless you have no other alternative

I'm unfortunately still unable to get this to uninstall correctly. Tried everything suggested so far.
I'm now getting the attached error when I try to uninstall. It does show that I have the newest version installed according to Add/Remove Programs

So did you download the microsoft troubleshooter linked above, and what did it return when you select the 3CX app from it?
