DIAGCAB Troubleshooting
Typical DIAGCAB Opening Challenges
Microsoft Windows Disappeared
You attempt to load your DIAGCAB file and get an error such as "%%os%% Can't Open The DIAGCAB File Extension". Generally, this is experienced in %%os%% because Microsoft Windows isn't installed on your PC. Your operating system cannot associate your DIAGCAB with Microsoft Windows, so double-clicking the file won't work.
Tip: If you have another software that you know opens DIAGCAB files, you can select it by hitting the "Show Apps" button.
Wrong Version of Microsoft Windows is Installed
Your Troubleshooting Pack Cabinet File file is incompatible with Microsoft Windows because you might have the wrong version installed. Visit the Microsoft Corporation website to download (or purchase) the latest version of Microsoft Windows. This issue mainly occurs when your Troubleshooting Pack Cabinet File file was created by a newer version of Microsoft Windows than you have on your PC.
Tip: Sometimes you can get a clue about the version of DIAGCAB file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).
Ultimately, most of the difficulties opening DIAGCAB files are due to having the wrong version of Microsoft Windows installed.
