Error importing software into Software Catalog

I am using Symantec Management Console 7.6 and am trying to import a software package into the Software Catalog. I open the Software Catalog and click Import. For the package source I chose Access package from an existing UNC. I enter in the location and click Display Location. The package contents appear and when I click Next I receive this error There was a problem parsing the submitted installation file. I receive this error for any software packages I try to import. Has anyone seen this before and know how to fix it? Thanks.
