A while back, I refused to even touch viewer 2 after trying it out once or twice, so I began using the Phoenix viewer only. Then they came out with Firestorm, and I started getting used to the interface, and thought I would give the official viewer 2 a try again. And since mesh is now available on a few sims, I wanted to see how that looked as well. So I went to use the beta viewer, and when I double clicked on the icon on my desktop, it would not open. I then tried another official viewer, and got the same result. So, the other day, I completely removed ALL second life viewers from my computer completely. I then installed ONLY the official viewers, and got the same result. After sitting in live chat with a Linden for about 45min, she basically told me that i am SOL cause the downloads are 32bit, and my comp is 64bit, and she showed me a JIRA link where someone was requesting a 64bit version. Frankly, i think its sucky, cause i can usually run 32bit programs on my computer with no issues. And I used to be able to run the official viewers on this computer, and have not had any major changes made to the system, other than microsoft updates or whatever, so I have no idea why I cant run them anymore. I also just downloaded Kirstens viewer, and am having the same exact result. I click the icon, the mouse shows the "working" symbol, then nothing. I tried running the compatability troubleshooter, but it did nothing. Tried running it as compatable with windows vista and XP (my machine is win7), and still nothing. I can run the phoenix/Firestorm viewers with NO issue, so what the hell is up with this??? Someone please HALP ME! :smileysad:
