OO File Complications

Troubles Opening OO Files

Free Pascal Not Present

You attempt to load your OO file and get an error such as "%%os%% Can't Open The OO File Extension". Usually, this is because you do not have Free Pascal for %%os%% installed. 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 you have another program installed that you know will open your OO, you can select it from the other programs listed (see "Show Apps").

Free Pascal is Out-of-Date

Occasionally, you might have an outdated version of Free Pascal installed that's incompatible with your Free Pascal Object File For OS/2 Version type. Download the latest Free Pascal version from the Open Source website to ensure you have the correct one installed. Most of the time your Free Pascal Object File For OS/2 Version file was created by a newer Free Pascal than what you have installed.

Tip: Investigate your OO file by right-clicking and selecting "Properties" to find clues on what version you need.

Regardless, most of the OO file opening problems relate to not having the right version of Free Pascal installed.

Other OO File Issues

Even with the correct version of Free Pascal installed, you can still experience difficulties opening OOs. There can be other issues - unrelated to software - preventing you from opening OO files. Problems unrelated to software:

• Invalid OO file references in the Windows Registry (the "phonebook" of the Windows Operating System)
• Corruption of the OO file description inside the Registry
• Free Pascal or another OO application experienced a flawed installation
• Something has caused file corruption of your OO
• Malware-tainted OO file can't be opened
• Device drivers of the hardware associated with your OO file are corrupt or out-of-date
• Your PC doesn’t have enough available resources to open the Free Pascal Object File For OS/2 Version file
