CLASS Troubleshooting

Troubles Opening CLASS Files

Missing Eclipse IDE for Java Developers

You attempt to load your CLASS file and get an error such as "%%os%% Can't Open The CLASS File Extension". Customarily, this means that Eclipse IDE for Java Developers is not installed on %%os%%. You won't be able to double-click to open your CLASS because your OS doesn't know what to do with it.

Tip: Another CLASS-related program can be selected to open the file by clicking "Show Apps" and finding the application.

Eclipse IDE for Java Developers is Out-of-Date

Sometimes your installed version of Eclipse IDE for Java Developers won't support your Java Class File file. If you do not have the proper version Eclipse IDE for Java Developers (or any of the other programs listed above), you may need to try downloading a different version of it, or one of the other software applications listed above. This problem is predominately due to having a Java Class File file version that was created by a newer version of Eclipse IDE for Java Developers than what you have installed on your PC.

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

Conclusion: The majority of CLASS file opening issues are due to not having the correct Eclipse IDE for Java Developers version installed.
