SYMPTOMS
You have Dbgrid16.ocx and Dbgrid32.ocx controls on your Windows 95 or Windows 98-based system that are in use by two different applications. One application uses the 16-bit control (Dbgrid16.ocx) and another application uses the 32-bit control (Dbgrid32.ocx). If you start the 16-bit application and then try to start the 32-bit application, the 32-bit application fails and returns the following error message:

Component 'DBGRID32.OCX' or one of its dependencies not correctly registered: a file is missing or invalid.

The problem does not happen if you run these applications on Windows NT 4.0, Windows 2000, or Windows XP. Also, it does not happen if you start the 32-bit application first and then start the 16-bit application.
