Universe Test Connection after upgrade

Hi all,

I'm testing the universes I have upgraded from 3.1 to 4.1. I have this "issue" when I do these checks from my PC:

- with BOE 3.1 Universe Designer if I open the Universe "A" and I check the connection of the universe (File > Parameters > Connection Test) the are no problems

- If I open a webi report based on the upgraded universe "A" from the Launchpad on BI 4.1 there are no problems

but

- with BI 4.1 Universe Designe Tool if I open the same upgraded Universe "A" and I do the same check (File > Parameters > Connection Test) the error is "The server is not responding! (SBO0001)" - "CS: COM Provider CLSID not specified or erroneous".

What's the problem ?

Thanks,

Michele
