Understanding MOP Issues


Typical MOP Opening Challenges

MOPAC Disappeared

When you double-click your MOP file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Customarily, this means that MOPAC is not installed on %%os%%. Your operating system cannot associate your MOP with MOPAC, so double-clicking the file won't work.


Tip: If you don't have MOPAC installed, and you know of another program to open your MOP file, you can try opening it by selecting from the programs listed under "Show Apps".


Wrong Version of MOPAC is Installed

Sometimes your installed version of MOPAC won't support your MOPAC Input Format file. If you've got the wrong version of MOPAC installed, you'll need to install the correct version. Most of the time your MOPAC Input Format file was created by a newer MOPAC than what you have installed.


Tip: Find clues on the correct software version by right-clicking your MOP file and clicking "Properties".


Summary: Not having the right MOPAC version on your computer can cause problems opening MOP files.


Other MOP File Opening Causes

Even with the correct version of MOPAC installed, you can still experience difficulties opening MOPs. If you are still having problems opening MOP files, there may be other issues that are preventing you from opening these files. Issues that aren't software-related:

  • Corrupt Windows Registry file path references for MOP
  • Mistaken removal of the Windows registry MOP description
  • MOPAC or another MOP application experienced a flawed installation
  • File corruption affecting your MOP file
  • MOP file integrity has been compromised by malware
  • Device drivers of the hardware associated with your MOP file are corrupt or out-of-date
  • Your computer does not have the adequate system resources to open the MOPAC Input Format format
