Yes, that finally did it!

Yeah I read the German article and just scanned through the English one so I accidentally skipped that line.

Thank you for solving my issue!

Best regards

yes, exactly.

What it should look like: What it actually looks like, after running Bandicam:

My original username is just "Philip" and the wrong one is "phili" which apparently Windows creates by using the first five letters from the connected outlook account. Also yes, I am running the German version of Windows but all folders are still named in English, only displayed ...

As the title states Bandicam creates a new user folder on my C: drive. Structure as follows: C:\Users\*mentionendwrongusername*\AppData\Roaming\Bandicam Company\BANDICAM and in the last folder there is a file called version.ini. Every time I delete the folder it apperas again after I start Bandicam....
