Common Problems Opening MQD Files

Malete Disappeared

You attempt to load your MQD file and get an error such as "%%os%% Can't Open The MQD File Extension". If this is the case, it's usually due to the fact that you do not have Malete for %%os%% installed on your computer. You won't be able to double-click to open your MQD because your OS doesn't know what to do with it.

Tip: If you know of another program that can open your MQD file, you can try opening it by selecting the application from the programs listed.

Obsolete Version of Malete

Occasionally, you might have an outdated version of Malete installed that's incompatible with your Malete Query Data File type. If you've got the wrong version of Malete installed, you'll need to install the correct version. The primary cause of this problem is that your Malete Query Data File file was created by a different (newer) version of Malete than what's installed.

Tip: Investigate your MQD file by right-clicking and selecting "Properties" to find clues on what version you need.

Ultimately, most of the difficulties opening MQD files are due to having the wrong version of Malete installed.
