LGS File Complications

Issues Opening LGS Files

Microsoft Windows Disappeared

When you double-click your LGS file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". If so, it typically means that you don't have Microsoft Windows installed for %%os%%. Your operating system cannot associate your LGS with Microsoft Windows, so double-clicking the file won't work.

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

Incorrect Microsoft Windows Version

Your Microsoft Windows Application Log File file is incompatible with Microsoft Windows because you might have the wrong version installed. You will need to download a newer version of Microsoft Windows if you don't have the right version. 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: Sometimes you can get a clue about the version of LGS file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

Summary: Not having the right Microsoft Windows version on your computer can cause problems opening LGS files.

Other Causes of LGS File Opening Problems

You can still experience errors opening LGS files even with the latest version of Microsoft Windows installed on your PC. There can be external issues inside of %%os%% that are causing these errors when opening LGSs. Other contributing causes:

• Windows Registry LGS file paths that are incorrect
• Mistaken removal of the Windows registry LGS description
• Corrupt install of Microsoft Windows or other LGS-related program
• Something has caused file corruption of your LGS
• Your LGS is infected with malware
• Drivers associated with LGS software need to be updated
• Windows cannot load your Microsoft Windows Application Log File file due to insufficient resources (eg. RAM)
