HM2 Troubleshooting
Frequent HM2 Opening Issues
Missing Help & Manual
Double-clicking your HM2 file prompts the message "%%os%% Can't Open HM2 File". If so, it typically means that you don't have Help & Manual installed for %%os%%. You won't be able to double-click to open your HM2 because your OS doesn't know what to do with it.
Tip: When another HM2 application is installed, you can choose to open it by selecting "Show Apps" and using that program.
Help & Manual is Out-of-Date
In some cases, you might have a newer (or older) version of a Help And Manual 2 Project file that is unsupported by your installed application version. If you do not have the proper version Help & Manual (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 issue mainly occurs when your Help And Manual 2 Project file was created by a newer version of Help & Manual than you have on your PC.
Tip: Find clues on the correct software version by right-clicking your HM2 file and clicking "Properties".
Summary: Not having the right Help & Manual version on your computer can cause problems opening HM2 files.
