Windows client in restricted area

Hy, I Have to install seafile desktop client on a win7 Desktop in a restricted area. That means on that Machine ( a cnc Machine ) I have not full access to the Windows System. So I did the installation → running. I was able to set up my Account and Library.
But i cannot access the Main window to set up the https settings.
Where is the Information stored ( ini or something else ) so i’m able to cancel the certificate check.
Sorry for my english…
