Troubleshooting Problems Opening XSN Files

Typical XSN Opening Challenges

Microsoft InfoPath is Not Installed

When you double-click your XSN file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Usually, this is because you do not have Microsoft InfoPath for %%os%% installed. The OS won't know what to do with your XSN file, so double-clicking to load the file doesn't work.

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

Microsoft InfoPath is Out-of-Date

In other instances, your InfoPath Form Template File file version may not be supported by your version of Microsoft InfoPath. Installing the latest version of Microsoft InfoPath from Microsoft Corporation is recommended. Your InfoPath Form Template File file was probably created by a newer release of Microsoft InfoPath than what's currently installed your computer.

Tip: Sometimes you can get a clue about the version of XSN file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

Summary: In either case, the majority of problems opening XSN files are related to not having the correct software application installed on your computer.
