When attempting to navigate to the SELECTServer Administrative website you may see the following error: Server Error in '/BSS' Application. If you're currently running a 64-bit Server and have installed the 64-bit SELECTServer application, you will want to verify that the SELECTServer Application Pool is configured to run in 64-bit mode. To check this in IIS 7.xx, open (IIS Manager) Internet Information Services Manager and click Application Pools from the Connections pane. Then right-click on the SELECTServer Application Pool and choose Advanced Properties. In the General section click on Enable 32-bit Applications and choose False from the drop down menu, click Ok to save changes. Run IISRESET and refresh the Website.
IIS7.xx allows you to run both 32-bit and 64-bit applications at the same time on different worker processes by utilizing this feature.
