Service Studio will not go passed loading popup
Platform Version
11.14.1 (Build 34445)


I am having an issue with the latest Outsystems Servie Studio application. When i try to start SS, i can only see the loading bar filling up and than it just does nothing anymore. Iget the standard windows spinner like it's not responding but after a few seconds it disapears.

I've tried reinstalling, installing different version but nothing seems to work. Please help.

WRN: Assembly binding logging is turned OFF.

To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.

Note: There is some performance penalty associated with assembly bind failure logging.

To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
