1CD File Complications

Troubles Opening 1CD Files

Unknown Software Not Present

If you attempt to load your 1CD file, you experience a message such as "Can't Open 1CD Files". When this happens, it is commonly due to Unknown Software missing in %%os%%. Your operating system cannot associate your 1CD with Unknown Software, so double-clicking the file won't work.

Tip: When another 1CD application is installed, you can choose to open it by selecting "Show Apps" and using that program.

Outdated Unknown Software

In some cases, you might have a newer (or older) version of a Unknown File Type file that is unsupported by your installed application version. If you've got the wrong version of Unknown Software installed, you'll need to install the correct version. 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: If you right-click on your 1CD file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Summary: Not having the right Unknown Software version on your computer can cause problems opening 1CD files.

Associated Difficulties Loading 1CD Files

Assuming you have the right Unknown Software version installed, other problems can prevent you from opening 1CD files. If you are continuing to have errors with loading 1CD files, other external issues might be to blame. Additional factors include:

• 1CD file references in the Windows Registry are broken
• Unintentional removal of the description of the 1CD file inside the Windows Registry
• Incomplete or bad installation of a software application associated with the 1CD format
• Your 1CD file is corrupted (issues with your Unknown File Type file itself)
• Your 1CD is infected with malware
• Device drivers of the hardware associated with your 1CD file are corrupt or out-of-date
• Windows has inadequate resources to open your Unknown File Type file
