Troubleshoot MPT Files
Common Problems Opening MPT Files
Microsoft Project 2016 is Not Installed
You attempt to load your MPT file and get an error such as "%%os%% Can't Open The MPT File Extension". If so, it typically means that you don't have Microsoft Project 2016 installed for %%os%%. You won't be able to double-click to open your MPT because your OS doesn't know what to do with it.
Tip: Another MPT-related program can be selected to open the file by clicking "Show Apps" and finding the application.
Obsolete Version of Microsoft Project 2016
Occasionally, you might have an outdated version of Microsoft Project 2016 installed that's incompatible with your Microsoft Project Template type. If you've got the wrong version of Microsoft Project 2016 installed, you'll need to install the correct version. Most of the time your Microsoft Project Template file was created by a newer Microsoft Project 2016 than what you have installed.
Tip: Find clues on the correct software version by right-clicking your MPT file and clicking "Properties".
Summary: In either case, the majority of problems opening MPT files are related to not having the correct software application installed on your computer.
Additional MPT Opening Issues
Errors opening Microsoft Project Template files can still occur even with the latest Microsoft Project 2016 software installed on your computer. If you are still having problems opening MPT files, there may be other issues that are preventing you from opening these files. Problems unrelated to software:
- MPT file references in the Windows Registry are broken
- Accidental deletion of the description of the MPT file in the Windows registry
- Corrupt install of Microsoft Project 2016 or other MPT-related program
- File corruption affecting your MPT file
- Your MPT is infected with malware
- MPT-related hardware has device drivers that obsolete
- Too many applications are open on your PC to load your Microsoft Project Template file successfully
