64D Troubleshooting

Issues Opening 64D Files

VICE Isn't There

You attempt to load your 64D file and get an error such as "%%os%% Can't Open The 64D File Extension". When this happens, it is commonly due to VICE missing in %%os%%. You won't be able to double-click to open your 64D because your OS doesn't know what to do with it.

Tip: If you have another software that you know opens 64D files, you can select it by hitting the "Show Apps" button.

Incorrect VICE Version

In other instances, your C64 PC64 Emulator File file version may not be supported by your version of VICE. Download the latest VICE version from the Open Source website to ensure you have the correct one installed. 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: You can sometimes get hints about the right program version by right-clicking on the 64D file, selecting "Properties", and looking at the version information.

Primarily, problems experienced when opening 64D files are due to having the incorrect version of VICE installed on your computer.
