Unable to open Manager

I am not able to open the manager. I have installed the program.

I moved your question to a new topic. It has nothing to do with custom reports.

Search the forum with your question. Many, many topics address possible problems. If they don’t solve it, you need to furnish considerable extra detail about edition, version, operating system, and your step by step actions, error messages or behavior, etc. You have given nothing to go on.
