How to solve 'The installation source for this product is not available' error?
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
