Flowster Studio installer crashed by opening the ui during a component update


You want to upgrade a single component installation of Flowster Studio to Flowster Studio 5.3, but the installer gui doesn’t open or crash.


  1. Open the Registry Editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Flowster Solutions\Flowster Studio

  2. Check the entry CMP_MainRestApiAddress, this entry must have the RestAPI Address eg. https://flowsterrestapi:5500 assigned. If your entry have the value 0 assigned, add the url of your RestAPI and try to start the installer again.
