Sources of DICPROOF Problems

Troubles Opening DICPROOF Files

Microsoft Excel Removed

Double-clicking your DICPROOF file prompts the message "%%os%% Can't Open DICPROOF File". Generally, this is experienced in %%os%% because Microsoft Excel isn't installed on your PC. This will prevent you from double-clicking to open the DICPROOF file because the OS doesn’t know how to handle it.

Tip: If you have another software that you know opens DICPROOF files, you can select it by hitting the "Show Apps" button.

Incorrect Microsoft Excel Version

In some cases, you might have a newer (or older) version of a Microsoft Dictionary Proofing File file that is unsupported by your installed application version. Visit the Microsoft Corporation website to download (or purchase) the latest version of Microsoft Excel. This issue mainly occurs when your Microsoft Dictionary Proofing File file was created by a newer version of Microsoft Excel than you have on your PC.

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

Conclusion: The majority of DICPROOF file opening issues are due to not having the correct Microsoft Excel version installed.
