Click to expand.Yes. The update is only ~5.2MB. After putting the installer on your flash drive and inserting the flash drive into your home computer, run the installer and it should update your game to the latest version, 1.12a. Since your game is installed and you just want to update, re-downloading the client (which is much bigger in size than a cumulative patch) isn't necessary. However, when you get a chance, it's definitely advisable to register your game with a Battle.net 2.0 account for future reference. Re: manually installing patches crap, I haven't noticed there is a second page to the thread and now my reply doesn't quite make sense MAKE SURE!!!! That you have the LOD PATCH not the CLASSIC patch (assuming you are trying to upgrade LoD.
If it's CLassic you wonna upgrade, get one for classic). One will not work with the opposit version of the game even if ten thousand hells of Lord Chaos broke lose! I tried changing the patch of my d2 and I've downloaded at least 7 Classic patches before I realised I need one for LOD sooo, yeah, make sure you got the right version of the game. Re: manually installing patches Installer wants to go online for installing. You need to download the correct PATCH. - For this use Firvagor's links. Then run the LODPatch_112a.exe on your home computer.
It doesn't matter from where you run it, but you can't have D2 running on background. It will update your installation for current (1.12a) version. If it doesn't check the obvious - if the files in your install directory aren't marked as read-only, if you don't run your Diablo from different directory etc.
If you have MAC instead of PC. Afterall tried, reinstall the original diablo and LOD and then apply the patch again.
