CA3 File Complications

Troubles Opening CA3 Files

WK-1800 is Not Installed

Double-clicking your CA3 file prompts the message "%%os%% Can't Open CA3 File". Usually, this is because you do not have WK-1800 for %%os%% installed. Your operating system cannot associate your CA3 with WK-1800, so double-clicking the file won't work.

Tip: If you have another software that you know opens CA3 files, you can select it by hitting the "Show Apps" button.

Obsolete Version of WK-1800

Your Casio WK-1800 Save All Data file is incompatible with WK-1800 because you might have the wrong version installed. You will need to download a newer version of WK-1800 if you don't have the right 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: Investigate your CA3 file by right-clicking and selecting "Properties" to find clues on what version you need.

Regardless, most of the CA3 file opening problems relate to not having the right version of WK-1800 installed.
