Error 339: THREED32.OCX is not correctly registered

Normally, this error requires assistance from a computer technician.

Run REGSVR32THREED32.OCX to produce an error code (for example, "0x80020009").

Generally, this error indicates that the original owner or primary user of the computer installed some software, and the registry entries have a restrictive permission setting. If you can log on to the computer with that user name, you might be able to install the software. Otherwise, advanced technical support is needed to follow the instructions found via Google for the error code reported by REGSVR32.

If, instead of an error code, REGSVR32 terminates in a program crash (Error performing inpage operation):

  1. Find THREED32.OCX in the\Windows\SYSTEM32 folder or WINNT\SYSTEM32 folder.
  2. Rename it to THREED32.OCY.
  3. Uninstall the program if it is available in "Add-Remove Programs."
  4. Reinstall the program.

If this is not successful, assistance is required from a computer technician.
