How to uninstall CFW 10 if it is not listed in the installed app list

Hi all,

I am using CFW version under Win10/German.
I have downloaded the installer for version
But it tells me that it can not remove my actual version an that I have to do this manually first.
But CFW is not listed in the installed apps list.
So how to remove the actual version from my computer?
Is there a seperate removal tool?

I tried to install the version a second time to get the program back into the
installed apps list, but get also here the messeage that I have to remove the current version

Any help is much appreciated

try to use the tool mentioned here
