Hi,

The game isn't available via Microsoft's site anymore, but a fellow named Lucas C has managed to patch the installer for modern systems.

MS Plus full installer with Labyrinth Plus! included:

....and that's it, if you want to play the base game on Win10 / Win11.

Bonus Addon pack (adds My Labyrinth mode with 20 extra levels)

In case you're having trouble getting Labyrinth Bonus Addon Pack to work (like I had), here's a Youtube guide showing step by step how to install it:

If you can't watch this for whatever reason (it might be gone in a couple of years), here's the guide:

1. Download the addon pack from Microsoft's website:

http://download.microsoft.com/download/plus/LABBONUS/1/WXP/EN-US/PlusLabyrinthBonus.exe

2. Try to run it

3. If it shows an error - "Error creating process (...) cannot find the file specified", then don't close this window

4. Keeping the error window open, go to:

c:\Users\YOURUSERNAME\AppData\Local\Temp\IXP000.TMP\

Note: if the last folder - IXP000.TMP doesn't exist, go ahead and create it, then close the error message and open the installer again

5. Double click the Patch003.msp file, which should be located in c:\Users\YOURUSERNAME\AppData\Local\Temp\IXP000.TMP\

Note: If that method doesn't work, you can open the installer with 7-Zip, unpack the file to any location and run it from there.

Cheers!
