I have a problem when using shared datasets and datasources on Report Builder 3.0.
The SQLServer I am using is 64bit. Therefore the datasets are 64bit connections and deployed them to the report Manager.
When I connect to the Report Manager url with report builder I can create the report but when I go to run it I get the version mismatch error. This is due to the report Builder being 32bit application. I cannot find the 64bit application of the reportbuilder? Is there one? If not will they be creating one?
