Sources of UPR Problems

Issues Opening UPR Files

Apophysis Removed

You encounter an error message such as "%%os%% Can't Open UPR Files" when trying to open your UPR. Generally, this is experienced in %%os%% because Apophysis isn't installed on your PC. You won't be able to double-click to open your UPR because your OS doesn't know what to do with it.

Tip: If you don't have Apophysis installed, and you know of another program to open your UPR file, you can try opening it by selecting from the programs listed under "Show Apps".

Apophysis Requires Update

Your Fractal Parameters File file is incompatible with Apophysis because you might have the wrong version installed. Visit the Open Source website to download (or purchase) the latest version of Apophysis. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.

Tip: Find clues on the correct software version by right-clicking your UPR file and clicking "Properties".

Summary: Not having the right Apophysis version on your computer can cause problems opening UPR files.

Additional UPR Opening Issues

Even with the correct version of Apophysis installed, you can still experience difficulties opening UPRs. Other UPR opening errors can be created by other system problems inside of %%os%%. Additional factors include:

• Invalid UPR file references in the Windows Registry (the "phonebook" of the Windows Operating System)
• Unintentional removal of the description of the UPR file inside the Windows Registry
• Incomplete or bad installation of a software application associated with the UPR format
• Something has caused file corruption of your UPR
• Malware-tainted UPR file can't be opened
• Device drivers for UPR-related hardware are out-of-date
• Windows cannot load your Fractal Parameters File file due to insufficient resources (eg. RAM)
