I have been trying to install Starcraft 2 but the launcher keeps crashing. I contacted Blizzard Tech Support and they said:
"I took a look at your system information that you sent us and it appears that there are some core services in your operating system that are crashing. This is likely the cause of StarCraft II not being able to be installed and I would recommend taking your computer to a local tech to see what may be causing these crashes. The name of the program crashing is the svchost.exe"
I know svchost is a container that runs several services, so I have no clue how to figure out which (if any) service(s) is crashing. Also, I have tried every remedy suggested by Blizzard and random forum people, but nothing has worked. Nothing. At. All.
If you need specifics or computer logs let me know!
