Internal server error http 500, open document

I have a webintelligence cluster installation. IIS6.5 sp3W2003 sp1

When I open a report, I have an internal server error http error 500. In the log I see something like : "The specified module could not be found". But I don't now which module it is.

But I can open/refresh webi reports and create new webintelligence documents.

The error is only with .rep reports (created with Business Objects)in the webintelligence application. With the Business Objects local installation there aren´t problems, I can open/refresh the reports.

Any ideas?

Thanks
