“Option set name doesn’t match with the one from existing option set” error while importing solution in CRM 2011.

Hi,

We got this error while importing the solution in one of the option set fields. Our development server were still in RTM. This was a known issue in RTM.

Installing the Update Rollup 1 and restarting the server fixed the issue.
