When starting the software, the following error may occurs. Often the software was running without issue prior to this problem, and other errors may occur when other tools are used to access catalogs or their contents.Internal ErrorError Message: Unrecognized database format "C:\ProgramData\Bentley\promis-e V8i(M)\promise Data\Catalogs\xxxx\catalog.mdb".TargetSite: Int32 NewConnection(System.String)DeclaringType: MDBProxy.ConnectionManagerAttributes: internalMemberType: Method
It is likely that the catalog.mdb file has been corrupted.
In more than one case, the problem was resolved by using the Compact & Repair Database function in Microsoft Access.
NOTE: If other users are also currently using the database file, you cannot perform a compact and repair operation.
NOTE: Categories, which appear as subfolders of the catalog in Catalog Manager, exist only in the catalog.mdb file. Therefore deleting this file will lose all Category information for that catalog. Categories are an optional organizational tool, and the catalog will function without them.
