The download bar is also stuck at 0% with it saying "Installing" perpetually.
Specs (note: my OS and literally every single driver is fully updated as of yesterday when I did mass updating):
Windows Vista 64-bit
Geforce 9800 GT
AMD Phenom II x2 (dual core) 3.1ghz per core
4gb DDR3 Ram
Not the greatest gaming rig but perfectly good enough for D3 according to the min/recommended specs.
As well, firewall and antiviral exceptions have been made, I'm running the launcher in admin mode, and I've tried compatibility modes, among other things.
Given the above, I assume this is a problem with the downloader and not my PC, but I haven't seen any official word on this issue so who knows. Am I wrong? Anyone have any idea?
