Missing Comdlg32.ocx error while running an application?

Component 'COMCTL32.OCX' or one of its dependencies not correctly registered:

A file is missing or invalid.

Every time I try to start up 'WORD' I get that message. This never happened before the latest Windows 10 upgrade.

How do I get rid of it, I'm finding it very frustrating.

I've tried the following 'cure' but it hasn't worked:

Outdated or missing comdlg32.ocx runtime library is causing this error. Here is a copy of

comdlg32.ocx (~60 Kb Zip). Download the file to the Desktop and extract the comdlg32.ocx to your the

comdlg32.zip and save to Desktop.

2. Unzip the file using WinZip or any other utility.

3. Extract comdlg32.ocx to Windows\System32 folder.

comdlg32.ocx Help

Hi,

Thank you for posting your query in Microsoft Community.

I understand the frustration when things don't work as expected.

I suggest you to follow the below steps.

When you install software that uses the comdlg32.ocx, the software should automatically register the file for you. In some cases your OCX file may not register properly, and as a result, will provide a "comdlg32.ocx not registered" error. Fortunately,
you can use a built-in utility called "Microsoft Register Server" (regsvr32.exe) to re-register your comdlg32.ocx file.

How to re-register comdlg32.ocx from an elevated command prompt (Windows 10).

• Click the Start button.
• Type "command" in the search box... DO NOT hit
  ENTER yet!
• While holding CTRL-Shift on your keyboard, hit
  ENTER.
• You will be prompted with a permission dialog box.
• Click Yes.
• Type the following command: regsvr32 /u comdlg32.ocx.
• Hit ENTER. This will UN-REGISTER your file.
• Type the following command: regsvr32 /i comdlg32.ocx.
• Hit ENTER. This will RE-REGISTER your file.
• Close the command prompt window.

Re-start the program associated with comdlg32.ocx error.

Hope this helps resolving the issue, if issue persists do get back to us we will be glad to help you.

Thank you.
