Cannot update or uninstall Adobe Acrobat DC.

Hi!

I'm running a PC with Windows 10 x64 (build 1809). I have tried to update Adobe Acrobat DC, but it won't update. Now I want to get rid of it, but I cannot uninstall it.

The update error is following: Error 1646

Uninstall error is as following: Uninstallation of the package is not supported.

There is also an error when trying to update the software from freshly downloaded package from Adobe homepage.

Please solve this.
