Typical SUJ Opening Challenges

Stacker Unlimited Isn't There

Double-clicking your SUJ file prompts the message "%%os%% Can't Open SUJ File". When this happens, it is commonly due to Stacker Unlimited missing in %%os%%. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.

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

Outdated Stacker Unlimited

In other instances, your Stacker Unlimited Job file version may not be supported by your version of Stacker Unlimited. If you've got the wrong version of Stacker Unlimited installed, you'll need to install the correct version. Your Stacker Unlimited Job file was probably created by a newer release of Stacker Unlimited than what's currently installed your computer.

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

Summary: Not having the right Stacker Unlimited version on your computer can cause problems opening SUJ files.
