Understanding CRF Issues

Frequent CRF Opening Issues

Cal3DViewer Removed

You attempt to load your CRF file and get an error such as "%%os%% Can't Open The CRF File Extension". If this is the case, it's usually due to the fact that you do not have Cal3DViewer for %%os%% installed on your computer. 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 CRF, you can select it from the other programs listed (see "Show Apps").

Cal3DViewer is Out-of-Date

In some cases, you might have a newer (or older) version of a Cal3D Binary Materials File file that is unsupported by your installed application version. If you've got the wrong version of Cal3DViewer installed, you'll need to install the correct version. This issue mainly occurs when your Cal3D Binary Materials File file was created by a newer version of Cal3DViewer than you have on your PC.

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

Summary: Not having the right Cal3DViewer version on your computer can cause problems opening CRF files.

Other Causes of CRF File Opening Problems

Assuming you have the right Cal3DViewer version installed, other problems can prevent you from opening CRF files. There can be other issues - unrelated to software - preventing you from opening CRF files. Other contributing causes:

• Corrupt Windows Registry file path references for CRF
• Corruption of the CRF file description inside the Registry
• Corrupt install of Cal3DViewer or other CRF-related program
• Your CRF file is corrupted (issues with your Cal3D Binary Materials File file itself)
• Past or present virus infection has affected your CRF
• Hardware associated with CRF has outdated drivers
• Windows cannot load your Cal3D Binary Materials File file due to insufficient resources (eg. RAM)
