ADA HDSuite v4 ‘OCX Error’ Solution

The HD Suite setup software provided by ADA was designed for Windows XP and some users have encountered issues when trying to install on some versions of Windows 7.

The issue is caused by certain required .ocx files not being registered in some versions of Windows 7.

The following guide provided by ADA should help anyone experiencing these ‘OCX Errors’ when installing or running the HDSuite software.

This document provides instructions for registering Windows System 32 .ocx files so the current ADA PCOS programs (designed for Windows XP) can be installed properly on the Windows Vista and Windows 7 operating systems.

In order to use the following procedures properly you must have Administrator Rights on the PC you are using and you must run the Command Prompt window as an Administrator.

  1. Click on the Start Menu
  2. Put your cursor over All Programs to open the list of programs.
  3. In the Programs Menu put your cursor over the Accessories option to open that menu then right click on the Command Prompt, right click on the pop-up context menu, select “Run as Administrator” option to open the window.

    All of the .ocx files must first be unregistered then re-registered for the following procedures to work properly. In addition the unregistration and re-registration procedure must be repeated for each of the .ocx files, as listed below:

    mscomm32.ocx
    tabclt32.ocx
    comdlg32.ocx
    mswinsck.ocx
    msinet.ocx
    msflxgrd.ocx

  4. Type in the following to change the director so you begin the unregistration process:

    cd c:\windows\system 32

    Note: Or change the directory (folder) to where your system32 files are located. The directory (folder) where your system32 files are located may not necessarily be named: windows

  5. To unregister a .ocx file type in the following command (in this example we are using the first .ocx file as listed above: mscomm32):

    regsvr32 /u c:\windows\system32\mscomm32.ocx

    Note: As above for the system32 files the specific path should be to where the .ocx files are located. Again, as above, this may not necessarily be in the directory (folder) named windows.

  6. Repeat this process for each of the .ocx files as listed above
  7. To re-register the files type in the following command (again using the mscomm32 .ocx as listed above):

    regsvr32 c:\windows\system32\mscomm.32.ocx

    Note: As above (step 4) for the system32 files the specific path should be to where the .ocx files are located. Again, as above, this may not necessarily be in the directory (folder) named: windows

  8. Repeat this process for each of the .ocx files as listed above

At this point the ADA PCOS program you wish to run should work/start properly.

Please note that on Windows 7 you may not be allowed to install a new rev. version of a ADA PCOS program over an old rev. version. In this case you will have to uninstall the older rev. version then reinstall the newest rev. version.

I hope this helps anyone struggling with the issue.

Thanks to ADA for documenting the fix.
