AEU File Complications

Troubles Opening AEU Files

Microsoft AutoRoute Not Present

You attempt to load your AEU file and get an error such as "%%os%% Can't Open The AEU File Extension". Customarily, this means that Microsoft AutoRoute is not installed on %%os%%. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.

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

Obsolete Version of Microsoft AutoRoute

Your Microsoft AutoRoute Express Europe Route Data file is incompatible with Microsoft AutoRoute because you might have the wrong version installed. Installing the latest version of Microsoft AutoRoute from Microsoft Corporation is recommended. This problem is predominately due to having a Microsoft AutoRoute Express Europe Route Data file version that was created by a newer version of Microsoft AutoRoute than what you have installed on your PC.

Tip: Sometimes you can get a clue about the version of AEU file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

Summary: In either case, the majority of problems opening AEU files are related to not having the correct software application installed on your computer.

Associated Difficulties Loading AEU Files

Assuming you have the right Microsoft AutoRoute version installed, other problems can prevent you from opening AEU files. Other AEU opening errors can be created by other system problems inside of %%os%%. Problems unrelated to software:

• Invalid AEU file references in the Windows Registry (the "phonebook" of the Windows Operating System)
• Unintentional removal of the description of the AEU file inside the Windows Registry
• Microsoft AutoRoute or another AEU application experienced a flawed installation
• AEU file corruption
• AEU file integrity has been compromised by malware
• Hardware related to AEUs has device driver corruption
• Too many applications are open on your PC to load your Microsoft AutoRoute Express Europe Route Data file successfully
