show multiple repository does not work after giving url in settings> user defined repositories

1. after installation launch uninstaller.exe (like maintain qt sdk)
2. set other repository in settings> repositories tab>user defined repositories
3. then select package manager and select next

it never shows any content from user defined repository

is there anything needs to be done with repogen.exe -u url option to create a new repository? I am not able to show or install packages from other url. always it scans and shows content from Default repositories.
