Q & A

- Why does the client not use the Lua settings? Use latest OpenSetup version. If that's already the case, use newer client.
- Why does OpenSetup not let me to save without Administrator? A few settings are still written to a location in the registry, that needs Administrator rights.
- I have have issues with OpenSetup, is there something I should add to my report?
When you experience the issue, press Shift+Esc inside the OpenSetup window until it closes and provide the generated log file (exename.log) along with your report.
