Thank you to Bill03948 for this fix:

.NET Framework and Random Map:Scenario Loader Caused An Unhandled Exception Error(s) Fix

Workaround (fix) tested with the following Operating Systems: Windows Home, Windows Media 64 bit, Vista Home Premium

Repro'd: Yes

Basic Information: The game requires additional 3rd party software to run. If the software is not loaded correctly, does not have the proper updates and/or patches or is "to new" of a version it will cause conflicts in the game. The Random Map Error is actually a continuation of the .NET Framework Error and requires additional updates. The game engine does not recognize .NET Framework 4.0 (or higher). If you have 4.0 (or higher) installed you'll have to remove it and go back to 2.0 and update to 3.5.

.NET Framework Error(s)

As explained above, The game engine requires .NET Framework to operate. The version it requires is 3.5. For some reason it will not recognize version 4.0. If you have 4.0 (or higher) on your system it will not detect .NET Framework at all. If you follow these steps it will fix your issue unless you have a specific issue:

NOTE: If at any time your computer asks to Restart follow the Install/Uninstall directions given by the program(s).

1. Go into ADD/REMOVE PROGRAMS and remove all .NET related files.

2. Go to Windows Update from your Start Menu.

3. Update .NET Framework. It will be either version 2.0 or 3.5

4. Follow ALL instructions to install.

5. Once installed, Run Windows Update again for updates and patches. Continue to do so until there's no more updates.

6. Launch AoE Online. The update window should load.

7. If the launch of AoE Online fails, run Windows Update again to see if the program requires additional updates.

8. Once you have the AoE Online Window running click on OPTIONS then FULL SCAN.

9. Once your game is up to date click PLAY.

10. You should now be able to enter the game. If not, check for additional updates/patches in Windows Update.

If you still can't enter the game, Please file a BUG REPORT.

Once in the game you may get a "Black Screen" Error or a black screen with an error message saying "Random Map: scenario Loader Caused An Unhandled Exception". This error message is related to the .NET Framework error message and is a continuation of non updated files and patches.

Random Map Error Fix:

1. Exit the game.

2. Run Windows Update and update ALL .NET Framework files

3. Follow the instructions and Restart if requested.

4. Run the game and try again. If you get the Random Map Error again, follow Steps 1 through 4 again.

NOTE: Average times you have to update again is 2-3 times but can vary.

If all updates are complete and you still get the Error Message, Please File a BUG REPORT
