ACEweb Installation Issues

These are some common issues that come up after installing ACEweb:

I can't open the ACEweb home.htm page

It is likely that IIS has been improperly setup, or is not currently running. You will need to verify your IIS settings.

If you get Access Denied messages when trying to open the Home.htm page, check that the IIS Internet User account has the required permissions.

Choices.dbf not Found

Your DataPath INI setting is incorrect, or your Application Pool Identity does not have permissions to access the Student Manager directory.

CoCreateInstance failed with err code 8000401a or 8000401b

Check to make certain the Application Pool Identity is correct (i.e. user name and password), and that the Identity account has permissions to access the Student Manager data directory.

IMPORTANT: the ACEweb User Account/Password cannot expire. If it expires, ACEweb will not be able to access the Student Manager directory.

HTTP Error 404.0 - Not Found or 404 - File or directory not found

Verify the Script Maps/Managed Handlers are set up correctly in IIS Handler Mappings.

404 Errors can also be caused when 32-Bit Applications are not enabled on the West Wind WebConnection Application Pool on 64-bit servers.

500 Internal Server Error

Check the Application Pool settingsfor the Default Web Site and the Wconnect application in IIS. Both must use the West Wind WebConnection application pool.

See the Default Application Pool section of the Windows Server 2008/2012 Configuration topic if you cannot set the Default Web Site to use the West Wind application pool.

CoCreateInstance failed with err code 80070005: Access is denied

You may see this error if the Application Pool Identity does not have the required permissions.

If that does not resolve the issue, check the Launch and Activation permissions on the ACEweb DCOM server. The Identity account on the West Wind WebConnection application pool must have Local Launch and Local Activation persmissions.

HTTP Error 404.2 - Not Found

If you are using the ISAPI module, check that the ISAPI Extension has been allowed for ACEweb.

401 - Unauthorized: Access is denied due to invalid credentials

Check that Basic and Windows Authentication are enabled for the Default Web Site and the Wconnect application in IIS.

SQL Version: Unknown Member oData when trying ACEweb links (e.g. showgroups.awp)

The Unknown Member oData error is a general symptom of a failed connection between ACEweb and the SQL database. Items to check:

• Missing/Invalid SQL Connection String in ACEweb.ini – make sure you have the correct connection string entered into the SQLConnectString INI setting.
• Improperly set up ODBC Connection – make sure you set up the ODBC connection properly on all machines accessing the SQL database.
• Make sure all the ACEweb log files were created during the port. This is the list of required ACEweb log files:

If you are missing any table, you can run the ACEweb.sql within the SQL Server Management Studio to create them.

• Make sure the Application Pool Identity has db_owner rights to the SQL database.
