Hi K2Developer-1,

You will find the error message and the information from your installertrace logs.

You may find it in it either of the paths below

- %Temp%
- [K2 install drive] K2SetupLog

Once you found the log, open it and look for the "Logged Error". You will need to resolve the issue stated in this log in order to proceed. Once the issue is resolved you may run the setup manager and select on the option "Recover"

Hi K2Developer-1,

It sounds like there is an issue with K2 Configuration Service. You can check if this service is running in Windows Services, the logs are located in [k2 installation folder] SourceCode.Configuration.ApiLogs.  Perhaps, it can be a port 5560 issue or an error on the on-prem certificate.
