I just installed Win 7 Enterprise 64bit on my computer at home. I had Win 7 RC before that. Last night, I could not get my phone to charge/sync at all. I'd plug it in; it'd pop up saying "installing drivers; it would say drivers failed to install. So I uninstalled through Device Manager and tried a couple times-- nothing. I started looking online and found Moto drivers (4.2.0 and 4.2.2) where a few people had similar issues. Those didn't help at all either. It worked fine on the RC OS (which was 64bit) and it works fine at work (same OS as home, just 32bit). Any suggestions? I wonder if I could find the drivers at work and carry them home?
