Understanding 0AR Issues

Typical 0AR Opening Challenges

Unknown Software Disappeared

You attempt to load your 0AR file and get an error such as "%%os%% Can't Open The 0AR File Extension". Generally, this is experienced in %%os%% because Unknown Software isn't installed on your PC. Your operating system cannot associate your 0AR with Unknown Software, so double-clicking the file won't work.

Tip: If you know of another program that can open your 0AR file, you can try opening it by selecting the application from the programs listed.

Wrong Version of Unknown Software is Installed

Your Uncommon File Extension file is incompatible with Unknown Software because you might have the wrong version installed. You will need to download a newer version of Unknown Software if you don't have the right version. Your Uncommon File Extension file was probably created by a newer release of Unknown Software than what's currently installed your computer.

Tip: Sometimes you can get a clue about the version of 0AR file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

Regardless, most of the 0AR file opening problems relate to not having the right version of Unknown Software installed.

More Causes of Problems Opening 0ARs

Assuming you have the right Unknown Software version installed, other problems can prevent you from opening 0AR files. Other 0AR opening errors can be created by other system problems inside of %%os%%. Additional factors include:

• Invalid 0AR file references in the Windows Registry (the "phonebook" of the Windows Operating System)
• The 0AR file description within the Windows Registry was removed
• Unknown Software or another 0AR application experienced a flawed installation
• Something has caused file corruption of your 0AR
• 0AR file integrity has been compromised by malware
• Device drivers of the hardware associated with your 0AR file are corrupt or out-of-date
• Too many applications are open on your PC to load your Uncommon File Extension file successfully
