A very short blog post.
I encountered this issue before.
And try to see this blog:
http://www.powerobjects.com/2014/09/18/dynamics-crm-error-importing-solutions-an-error-has-occurred-10/
Some will work, but unfortunately, this is not my root problem.
Then, in the end I found that it was because of the Duplicate File with the same name happened in my Source solution...
Not sure why this can happen I thought schema name should be unique..
Then in the end I just delete one of the file and re-export and re-import again.
It is quite difficult to trace.
Hope this helps you.
Thanks.
