Understanding MSHXML Issues

Common MSHXML Opening Problems

Missing Microsoft Windows PowerShell

You encounter an error message such as "%%os%% Can't Open MSHXML Files" when trying to open your MSHXML. If so, it typically means that you don't have Microsoft Windows PowerShell installed for %%os%%. The typical path of opening your MSHXML with a double-click won't work because %%os%% cannot make the program connection.

Tip: When another MSHXML application is installed, you can choose to open it by selecting "Show Apps" and using that program.

Incorrect Microsoft Windows PowerShell Version

Sometimes your installed version of Microsoft Windows PowerShell won't support your Windows PowerShell Script File file. If you do not have the proper version Microsoft Windows PowerShell (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. 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: If you right-click on your MSHXML file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Regardless, most of the MSHXML file opening problems relate to not having the right version of Microsoft Windows PowerShell installed.
