Sources of DCTX Problems

Typical DCTX Opening Challenges

Microsoft Office Removed

You attempt to load your DCTX file and get an error such as "%%os%% Can't Open The DCTX File Extension". If so, it typically means that you don't have Microsoft Office installed for %%os%%. This will prevent you from double-clicking to open the DCTX file because the OS doesn’t know how to handle it.

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

Incorrect Microsoft Office Version

It is possible that your version of Microsoft Office isn't able to open your Microsoft Office IME Open Extended Dictionary file due to incompatibility. Visit the Microsoft Corporation website to download (or purchase) the latest version of Microsoft Office. 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: Sometimes you can get a clue about the version of DCTX file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

Summary: Not having the right Microsoft Office version on your computer can cause problems opening DCTX files.
