Sources of STC Problems

Common STC Opening Problems

Adobe Contribute 6.5 Isn't There

You encounter an error message such as "%%os%% Can't Open STC Files" when trying to open your STC. Generally, this is experienced in %%os%% because Adobe Contribute 6.5 isn't installed on your PC. Your operating system cannot associate your STC with Adobe Contribute 6.5, so double-clicking the file won't work.

Tip: If you don't have Adobe Contribute 6.5 installed, and you know of another program to open your STC file, you can try opening it by selecting from the programs listed under "Show Apps".

Incorrect Adobe Contribute 6.5 Version

Sometimes your installed version of Adobe Contribute 6.5 won't support your Contribute Connection Key File file. Download the latest Adobe Contribute 6.5 version from the Adobe Systems Incorporated website to ensure you have the correct one installed. The primary cause of this problem is that your Contribute Connection Key File file was created by a different (newer) version of Adobe Contribute 6.5 than what's installed.

Tip: Right-clicking on your STC, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.

Conclusion: The majority of STC file opening issues are due to not having the correct Adobe Contribute 6.5 version installed.

Other Causes of STC File Opening Problems

Assuming you have the right Adobe Contribute 6.5 version installed, other problems can prevent you from opening STC files. If you are continuing to have errors with loading STC files, other external issues might be to blame. These issues include:

• Corrupt Windows Registry file path references for STC
• Accidental deletion of the description of the STC file in the Windows registry
• Corrupt install of Adobe Contribute 6.5 or other STC-related program
• Something has caused file corruption of your STC
• Your STC is infected with malware
• Hardware related to STCs has device driver corruption
• Insufficient system resources to successfully open Contribute Connection Key File files
