When starting Dundas Dashboard you see the following error message:Could not load file or assembly Microsoft.SqlServer.BatchParser, Version=10.0.0.0,...
This message is normally related to an architecture mismatch between your system and Dundas Dashboard. For example, you may have have 32-bit drivers or SQL Server components installed but are running Dundas Dashboard as a 64-bit application.
to see how you can check if Dundas Dashboard is running under a 64-bit or 32-bit application pool in IIS.
If there is a mismatch with your system try to change it to match your system by changing the “Enable 32-bit Applications” property (True means 32-bit, False means 64-bit) under the Advanced settings of the Application Pool.
If this cannot be changed then try installing the drivers that will match the architecture with that of Dundas Dashboard.
Installing the right drivers or changing Dundas Dashboard to the right architecture should fix the problem.
