Visual Studio Addon Template not detecting Corel Draw 2018

Hey guys, 

maybe i'm in the wrong forum, but i couldn't find a way how to create a new thread in the developer forums. 

I wanted to develop an addon via the .NET SDK in C#, sadly the template selection doesn't seem to detect my Corel Draw Version (Corel Draw Graphics Suite 2018 OEM 32bit.

I'm logged into my account in Corel Draw. 

The weird thing is, i've also tried to simply add a new menu using .xlst files as destribed in a tutorial, but not even that seems to show up. 

Can someone give me some clue about what could be wrong here? 

I'd appreciate it!

Thanks in advance!
