Troubleshooting Problems Opening LDL Files

Common LDL Opening Problems

Corel Paradox Removed

When trying to open your LDL file, you get the error "Can't Open LDL File Type". When this happens, it is commonly due to Corel Paradox missing in %%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: Another LDL-related program can be selected to open the file by clicking "Show Apps" and finding the application.

Obsolete Version of Corel Paradox

It is possible that your version of Corel Paradox isn't able to open your Corel Paradox Delivered Library File file due to incompatibility. Installing the latest version of Corel Paradox from Corel is recommended. This issue mainly occurs when your Corel Paradox Delivered Library File file was created by a newer version of Corel Paradox than you have on your PC.

Tip: If you right-click on your LDL file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Conclusion: The majority of LDL file opening issues are due to not having the correct Corel Paradox version installed.

More Causes of Problems Opening LDLs

You can still experience errors opening LDL files even with the latest version of Corel Paradox installed on your PC. There can be external issues inside of %%os%% that are causing these errors when opening LDLs. These other problems include (listed in order from most to least common):
