SYMPTOMS
When launching Visual InterDev, an error message can occur stating that there is a version conflict between two or more ODBC system files.



CAUSE
Installing Peer Web Services on Windows NT Workstation 4.0 will always overwrite the ODBC files Odbcint.dll and Odbccp32.dll with version 2.50.30.6 of these files even if the files that already exist are more recent. If Visual InterDev is installed first, some of the ODBC files will be the version that shipped with Visual InterDev and some will get overwritten with older versions by the Peer Web Services install.

This behavior causes the version conflict message.



RESOLUTION
To get the ODBC files back in sync, remove Visual InterDev through the Control Panel Add/Remove Programs applet and then reinstall.

To avoid this problem altogether, install Peer Web Services before Visual InterDev. Or, you can install the latest version of MDAC.



STATUS
This problem has been resolved in Visual InterDev 6.0.



Steps to Reproduce Behavior
 Install Visual InterDev Client on Windows NT 4.0 Workstation. Check the version of Odbcint.dll and Odbccp32.dll in the Winnt\System directory. Install Peer Web Services on the same machine by following these steps:  Right-click Network Neighborhood. Select the Services tab.</li> Click Add, Microsoft Peer Web Services, and OK.</li> During the setup, accept the defaults.</li></ol> </li></ol>

Note that the versions of Odbcint.dll and Odbccp32.dll in the system dir are now 2.50.30.6.
