I used to have the version 2018.3.5 and upgraded it to 2020.2.1.
I then wanted to uninstall it to install the real last release 2020.2.1 (to have the proper folder :)) but then the uninstaller says : Uninstall hasn't detected folder of Webstorm installation, blabla.
I then decided to install the real 2020.2.1. This works well but I still can't uninstall the previous one.
Any idea ?
