When you develop your enterprise application and deploy your application as a window service, you may encounter the following problem :
"The installation source for this product is not available. Verify that the source exists and that you can access it."
In this case, you can not install a new version of windows service because the installed service is corrupted and exists in the system.
The installed service should be existed in "Administration Tools -> Services" and "Control panel -> Programs"
And to deploy or install a new version of service, you need to remove the two services.
Here are two steps to make it:
1. Use windows "Fix It" tool to solve the registry corruption problem

It will remove the installed programs.
2. Use "Service Control" command to delete the service
sc delete serviceName

It will remove the installed service.
If you have followed the previous steps, you should be able to install the new version of service.
Hope this helps!
