I exported 3 separate CRM 2015 unmanaged solutions to 3 zip files in May 2015. I have now created a new CRM environment and am trying to import the solutions but keep getting the error below for the solution that has all the entities.
"The Solution file is invalid. The compressed file must contain the following files at its root: solution.xml, customizations.xml, and [Content_Types].xml. Customizaiton files exported from previous versions of microsoft Dynamics CRM are not supported."
Any idea what i should do?
I have tried unzipping and zipping all the xml files and then tried again but nothing.
Thank you
