Troubleshoot 4WD Files
Common Problems Opening 4WD Files
WebMerge is Not Installed
You encounter an error message such as "%%os%% Can't Open 4WD Files" when trying to open your 4WD. If so, it typically means that you don't have WebMerge installed for %%os%%. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.
Tip: When another 4WD application is installed, you can choose to open it by selecting "Show Apps" and using that program.
WebMerge Requires Update
In some cases, you might have a newer (or older) version of a WebMerge Data List File file that is unsupported by your installed application version. Installing the latest version of WebMerge from Fourth World Systems is recommended. Most of the time your WebMerge Data List File file was created by a newer WebMerge than what you have installed.
Tip: Investigate your 4WD file by right-clicking and selecting "Properties" to find clues on what version you need.
Conclusion: The majority of 4WD file opening issues are due to not having the correct WebMerge version installed.
Other 4WD File Issues
Errors opening WebMerge Data List File files can still occur even with the latest WebMerge software installed on your computer. There can be external issues inside of %%os%% that are causing these errors when opening 4WDs. Problems unrelated to software:
- File references in the Windows Registry for 4WD are wrong
- Deletion of the 4WD file description from the Registry by mistake
- WebMerge or another 4WD application experienced a flawed installation
- 4WD file corruption
- Your 4WD has adversely impacted by malware
- 4WD-related hardware has device drivers that obsolete
- Insufficient system resources to successfully open WebMerge Data List File files
