Visual Difference in BI 4.1 SP1 Update 4 -- Not Working

Hello All,

We are on SAP BO 4.1 SP1 Update 4 (Red Hat Linux). The Visual Difference feature in CMC is not working for us when trying to compare 2 BIAR files. We are getting the following error:

[b]Plugin not found error. (VDS 00007)" [/b]

Let me know it this feature is working for any body? Also guide me how to troubleshoot this. Raised a SAP ticket on it but so far no solution yet.

Thanks
