We are getting below error while installing content porter from CME- using IE
application validation did not succeed. unable to continue
File, Tridion.ContentManager.ImportExport.CommonFacade.dll, has a different computed hash than specified in manifest.
This happened after we tried installing a patch for CP(hotfix 188.8.131.52095).
Can some one suggest a solution.
--- We are in the process of Upgrading to Sp2 Content Porter and the issue is resolved.
