Sources of LGN Problems


Issues Opening LGN Files

Microsoft Windows Removed

Double-clicking your LGN file prompts the message "%%os%% Can't Open LGN File". If this is the case, it's usually due to the fact that you do not have Microsoft Windows for %%os%% installed on your computer. The typical path of opening your LGN with a double-click won't work because %%os%% cannot make the program connection.


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


Wrong Version of Microsoft Windows is Installed

Sometimes your installed version of Microsoft Windows won't support your Microsoft Windows Application Log File file. You will need to download a newer version of Microsoft Windows if you don't have the right version. This problem is predominately due to having a Microsoft Windows Application Log File file version that was created by a newer version of Microsoft Windows than what you have installed on your PC.


Tip: You can sometimes get hints about the right program version by right-clicking on the LGN file, selecting "Properties", and looking at the version information.


Primarily, problems experienced when opening LGN files are due to having the incorrect version of Microsoft Windows installed on your computer.
