PRB: Setup Unable to Register an .ocx File Error

 Last reviewed: December 10, 1996
Article ID: Q160771
The information in this article applies to:
  • Microsoft Visual FoxPro for Windows, version 5.0

SYMPTOMS

When using setup disks created by the Setup Wizard to install an executable file, the set up process does not complete because the following error appears: 

   <filename.ocx> was unable to register itself in the System Registry
followed by the message: 

   Setup not completed successfully.
The Setup process then terminates.

CAUSE

The Setup program is unable to register the .ocx file because it is corrupted or the incorrect version.

RESOLUTION

Ensure that the .ocx file is located in the same folder as the executable file before the Setup Wizard compresses the files.

Next, check the version of the .ocx file being used with the executable file against the corresponding .ocx file located in the either the Windows\System or Windows\System32 folder. On Windows 95, the Windows\System folder contains the .ocx files that shipped with Visual FoxPro 5.0. On Windows NT 3.51 or 4.0, they reside in the Windows\System32 folder. To determine the version of an .ocx file, on Windows 95 or Windows NT 4.0, start Windows Explorer or My Computer, highlight the .ocx file, right-click (secondary click) and click Properties on the menu that appears, and press the Version tab. On Windows NT 3.51, highlight the file, and press the Alt and Enter keys.

The General tab provides information on the file size in bytes. This information is useful if you suspect file corruption. Again, compare the file being compressed with the file in the appropriate Windows\System folder.
