You can download Mechwarrior: Living Legends here.
If you don't already have Crysis Wars, the easiest way is to download the unofficial combined installer for both Crysis Wars and MWLL.
If you already have Crysis Wars, you should use the unofficial MWLL 0.7.1 installer. Your copy of Crysis Wars needs to be patched to version 1.5.
Download Official MWLL installer and just do what it says. You need Crysis Wars patched to version 1.5 before running the Official installer.
MWLL for purists.
First, you need Crysis Wars patched up to version 1.5
Download MWLL-CrysisWars-OpenBeta-Full-0.6.0.exe, MWLL-OpenBeta-Full-0.6.0.zip, MWLL-OpenBeta-Patch-0.6.1.zip. Run MWLL-CrysisWars-OpenBeta-Full-0.6.0.exe. Once you get to the MWLL updater, set its Updates directory to the directory where you downloaded the .zip files. You should also check 'Preserve downloaded files' just in case anything goes wrong.
If you get an error, install the game manually, per the following guide, originally posted by Bruno_007.
If it still doesn't run, install the vcredist packages from bin32 or bin64, depending on your architecture, located in the mwll folder.
If that fails as well, ask on the forums.
