Overview
This article describes how to check if Dundas Dashboard is running as a 32-bit or 64-bit application when installed on a 64-bit machine, as well as how to change between the two. This is necessary because the drivers for some data providers are specifically 32-bit or 64-bit and can only be used if Dundas Dashboard is running in the same mode.
IIS 6
Note: Whether or not applications run as 32-bit or 64-bit in IIS 6 is a global configuration setting. This will affect every application and not just Dundas Dashboard.
To see if applications are running in 32-bit or 64-bit mode, you can either check the value of the
Enable32BitAppOnWin64 metabase property, or open the task manager and look for an IIS worker process. If the process name says
w3wp.exe*32 then IIS is running in 32-bit mode.

To change the Enable32BitAppOnWin64 metabase property, please see the
IIS 6 documentation for more information and instructions.
IIS 7
In IIS 7, each application pool has a setting to run as 32-bit or 64-bit individually. Here is how to check and change it:
- Open the IIS management console:
- From the Start menu, click Run or use the search option.
- Type inetmgr, then press ENTER.
- Locate the application pool used by Dundas Dashboard. By default this will be named Dundas Dashboard {instance}.

- Select the application pool and go to the Advanced settings. If the flag Enable 32-bit Applications is set to True, Dundas Dashboard is running as 32-bit application. Otherwise it is running as a 64-bit application.
