RC_ Troubleshooting

Typical RC_ Opening Challenges

Microsoft Windows Help Not Present

Double-clicking your RC_ file prompts the message "%%os%% Can't Open RC_ File". If so, it typically means that you don't have Microsoft Windows Help installed for %%os%%. The OS won't know what to do with your RC_ file, so double-clicking to load the file doesn't work.

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

Obsolete Version of Microsoft Windows Help

It is possible that your version of Microsoft Windows Help isn't able to open your Microsoft WinHelp Compressed Help Document file due to incompatibility. If you've got the wrong version of Microsoft Windows Help 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 RC_ file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Summary: Not having the right Microsoft Windows Help version on your computer can cause problems opening RC_ files.
