Do this as an administrator. What I mean is, run command prompt as administrator and try it. I had the same error and solved this technique.

There should be more information in the assemblyname.InstallLog file. Check for errors first.

Check the application event log, run this:

eventvwr.msc

Here you can see the details of the real exception you are getting.

If you are in a config file System.ServiceModel

, the error you are getting could be caused by incorrect config settings.

You can follow this Windows Managed Service Installation guide if you are having a hard time installing.
