How to Fix tx4ole20.ocx Errors in 4 Steps (Time to complete: ~5-15 minutes)
If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your tx4ole20.ocx issue. These troubleshooting steps are listed in the recommended order of execution.
Step 1: Use Microsoft Register Server (regsvr) to Manually Register Your tx4ole20.ocx File
When you install File Viewer Lite, or another software that uses the tx4ole20.ocx dependency, the software should register the file automatically. Sometimes your OCX file won't get registered properly and will trigger a "tx4ole20.ocx not registered" error. Thankfully, Microsoft included a handy built-in utility called "Microsoft Register Server" (regsvr32.exe) to enable you to manually re-register your tx4ole20.ocx file.
How to re-register tx4ole20.ocx from an elevated command prompt (Windows XP, Vista, 7, 8, and 10):
- Hit the Windows Start button
- In the search box, type "command" (do not presss ENTER yet)
- While holding CTRL-Shift, hit ENTER.
- You will be prompted with a permission dialog box.
- Click Yes.
- Type this command: regsvr32 /u tx4ole20.ocx
- Hit ENTER. This process will UN-register your file, allowing you to RE-register it.
- Type this command: regsvr32 /i tx4ole20.ocx
- Hit ENTER. This process will RE-register your file.
- Close the command prompt window.
- Re-start File Viewer Lite.
Step 2: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.
To begin System Restore (Windows XP, Vista, 7, 8, and 10):
- Hit the Windows Start button
- When you see the search box, type "System Restore" and press "ENTER".
- In the search results, find and click System Restore.
- Please enter the administrator password (if applicable / prompted).
- Follow the steps in the System Restore Wizard to choose a relevant restore point.
- Restore your computer to that backup image.
If the Step 1 fails to resolve the tx4ole20.ocx error, please proceed to the Step 2 below.
Step 3: If recently installed File Viewer Lite (or related software), uninstall then try reinstalling File Viewer Lite software.
You can uninstall File Viewer Lite software by following these instructions (Windows XP, Vista, 7, 8, and 10):
- Hit the Windows Start button
- In the search box, type "Uninstall" and press "ENTER".

- Hit the Windows Start button
- In the search box, type "Update" and press "ENTER".
- In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
- If updates are available for download, click "Install Updates".
