Problem creating file SNAP Command-Line

I get this problem by installing SNAP:

What can I do here? Or can I still work with SNAP (sen2cor) without getting any Problems on the way?

Thank you!

Probably SNAP will work.
However, that the installer can’t add links to your Start menu indicates that your system has an unusual configuration.
Maybe the access rights are limited.
And as your system configuration is not as for the most people you might encounter more problems or if you’re lucky this is the only problem.

Yes, the rights are limited because I am not working on my computer (because it only has an 8GB RAM) but on the one at the university. I hope that is the only problem. We will see. Thank you for your answer.
