Sources of XSF Problems

Troubles Opening XSF Files

Microsoft InfoPath Removed

You encounter an error message such as "%%os%% Can't Open XSF Files" when trying to open your XSF. Customarily, this means that Microsoft InfoPath is not installed on %%os%%. The OS won't know what to do with your XSF file, so double-clicking to load the file doesn't work.

Tip: Another XSF-related program can be selected to open the file by clicking "Show Apps" and finding the application.

Microsoft InfoPath Requires Update

In other instances, your InfoPath Form Definition File file version may not be supported by your version of Microsoft InfoPath. You will need to download a newer version of Microsoft InfoPath if you don't have the right version. The primary cause of this problem is that your InfoPath Form Definition File file was created by a different (newer) version of Microsoft InfoPath than what's installed.

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

Conclusion: The majority of XSF file opening issues are due to not having the correct Microsoft InfoPath version installed.

Associated Difficulties Loading XSF Files

Even with the correct version of Microsoft InfoPath installed, you can still experience difficulties opening XSFs. There can be other issues - unrelated to software - preventing you from opening XSF files. Other contributing causes:

• File references in the Windows Registry for XSF are wrong
• Deletion of the XSF file description from the Registry by mistake
• Microsoft InfoPath or another XSF application experienced a flawed installation
• File corruption affecting your XSF file
• Your XSF is infected with malware
• Hardware associated with XSF has outdated drivers
• Insufficient system resources to successfully open InfoPath Form Definition File files
