OW Troubleshooting


Issues Opening OW Files

Free Pascal is Not Installed

When trying to open your OW file, you get the error "Can't Open OW File Type". When this happens, it is commonly due to Free Pascal missing in %%os%%. The typical path of opening your OW with a double-click won't work because %%os%% cannot make the program connection.


Tip: When you have another program installed that you know will open your OW, you can select it from the other programs listed (see "Show Apps").


Wrong Version of Free Pascal is Installed

In some cases, you might have a newer (or older) version of a Free Pascal 1.0.x Object File file that is unsupported by your installed application version. You will need to download a newer version of Free Pascal if you don't have the right version. Your Free Pascal 1.0.x Object File file was probably created by a newer release of Free Pascal than what's currently installed your computer.


Tip: Right-clicking on your OW, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.


Summary: In either case, the majority of problems opening OW files are related to not having the correct software application installed on your computer.


Other OW File Issues

Errors opening Free Pascal 1.0.x Object File files can still occur even with the latest Free Pascal software installed on your computer. If you are continuing to have errors with loading OW files, other external issues might be to blame. These other problems include (listed in order from most to least common):

  • OW file references in the Windows Registry are broken
  • The OW file description within the Windows Registry was removed
  • Incomplete or bad installation of a software application associated with the OW format
  • Something has caused file corruption of your OW
  • Past or present virus infection has affected your OW
  • Drivers associated with OW software need to be updated
  • Insufficient system resources to successfully open Free Pascal 1.0.x Object File files
