I recently got a desktop pc and have been trying to download the blizzard launcher.
If it does not it looks like you are in the same boat as the rest of us which really sucks. If that did not work for you and the app still isn't launching for you the next step is.... Seems a lot of people are having the same issue & there is yet to be a fix for it.
The one fix i have heard/read on one of the forums is to do a complete re-install of your OS which is not really a fix.
This unofficial "patch" allows you to play Diablo II in resolutions other than 640x480 and 800x600.
It is, for the most part, completed, but there are still a few issues that have not been worked out.
I have lost hours trying to fix this and nothing so far has worked. Hey it sound like you are having the same issue as the rest of us here.https://us.battle.net/forums/en/bnet/topic/20754325294?
page=1I am going to assume this is the first time you have tried installing the app on your PC so this solution may not work & if it does its more of a work around than an actual hit the Windows Key R the search %progamdata% look for the folder & then the Agent folder, once you have done that delete the agent folder & start the app again & hopefully that will work for you.If you're stuck longer than a few minutes on this screen, follow the troubleshooting steps below: If you have tried these steps and still require assistance, visit our Technical Support Forums (World of Warcraft) (Star Craft II) (Diablo III) (Hearthstone) (Heroes of the Storm) (Overwatch) or contact us.BLZBNTAGT00000840 Information on error BLZBNTAGT00000840 Repairing Blizzard Games Corrupted and damaged game files can create a wide variety of problems and errors.Passive changes include: “When this passive successfully prevents death (Final Service), the Necromancer is immune to incoming damage for 4 seconds.”While this won’t be the final version that will be released by the development team later in 2017, it does point to some things that won’t make it out of the beta phase.The new PTR update also adds Necromancer Set Dungeons to Adventure Mode, as well as a time limit to complete them in 5 minutes.You shouldn't notice any major drawbacks for using Direct Draw over Direct3D, so for most users this probably won't be a problem. You may use any of the normal command line options available when playing Diablo II, such as "-w" for windowed or "-direct -txt" for mods.
