Can't uninstall X3

I needed to install DSMinGW but that failed as I launched the DSMinGW.exe (Could not detect the installation https://i.imgur.com/xyPOjv5.png)

I decided to modify the X3 installation as mentioned in the manual. So I go to uninstall apps on control panel (win 10). Click modify and get this prompt https://i.imgur.com/kPIPPOv.png and after clicking yes I am greeted with this https://i.imgur.com/3Xzvg44.png

I then give up and decide to uninstall and do a new fresh installation...

and somehow despite selecting uninstall we meet again: https://i.imgur.com/kPIPPOv.png

So, cant add DSMinGW directly, cant modify X3, can't uninstall X3. What to do?

Dear Tjaš,

there was an issue with the DSMinGW installation, but it was fixed with the new installer.

You can find a new installer already on our web page.

As considers the upgrading Dewesoft, it looks like you have another version of Dewesoft X3 already installed on your PC. But it is strange that the software won't uninstall, we did not come across this issue before.

Regards
