Converting Managed Solution to Unmanaged/giving me error of Solution.xml does not exist.

Hi All,

I am following the below blog to convert Managed Solution to Unmanaged

community.dynamics.com/.../converting-managed-solutions-to-unmanaged-solutions-crm-2013

I open Solution.xml File in Notepad  and covert it to like below in 8 point of blog

You will notice lot of MissingDependency elements, remove them all and self close the MissingDependency tag like this <MissingDependency />

Now I Zip the files again and  import it to  development environment but when I import it to development environment, the solution not imported and it is giving me error of Solution.xml does not exist.

I followed each step as it is given in the blog. Not sure why it is not allowing me import to development environment.

Any help greatly appreciated.
