XS4 File Complications

Common XS4 Opening Problems

Missing Xess

When you double-click your XS4 file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Generally, this is experienced in %%os%% because Xess isn't installed on your PC. You won't be able to double-click to open your XS4 because your OS doesn't know what to do with it.

Tip: When you have another program installed that you know will open your XS4, you can select it from the other programs listed (see "Show Apps").

Xess Requires Update

Occasionally, you might have an outdated version of Xess installed that's incompatible with your XESS Worksheet type. If you do not have the proper version Xess (or any of the other programs listed above), you may need to try downloading a different version of it, or one of the other software applications listed above. Most of the time your XESS Worksheet file was created by a newer Xess than what you have installed.

Tip: Investigate your XS4 file by right-clicking and selecting "Properties" to find clues on what version you need.

Regardless, most of the XS4 file opening problems relate to not having the right version of Xess installed.
