Chance Small

I just now did something similar, I wasn't able to find a way to "extract" the files from the setup executable, even when running the installer, it didn't put driver files in the AppData/Local/Temp long enough for me to copy it somewhere. I installed the software/drivers, noticed there were driver files in the Program Files of the software. I copied the whole folder to somewhere safe, uninstalled it, then manually installed the drivers via Device Manager by pointing it to the folder I copied. I am happy, once again. Thanks everyone for your contributions!

I finally found the issue! I decided I'd start from scratch once more, and reinstall my OS... This time I made sure the VERY first thing I installed was QuickTime/Second Life. Much to my suprise, it worked! Next, I thought I'll install the software/drivers for my Biigfoot Networks Killer 2100 Gaming Network Card. When the install finished, it asked to reboot but I decided I'd try to run Second Life again before I did... FAILED. media_plugin_webkit error. I immediately uninstalled the software/drivers (didn't bother to reboot), ran Second Life again, and it worked like a charm! Unfortunately, in order to install the drivers for the Killer 2100 NIC, I have to install the software that's bundled with it, and if I uninstall the software, the drivers get uninstalled along with it; so I am unable to determine what specifically is creating the issue (software or drivers?). Eitherway, I'm sticking with my motherboard's ethernet in the mean time.

Okay, a bit of a status update on the topic of it being hardware specific... I went ahead and installed Windows 7 x64 on a Virtual Machine utilizing the same exact DVD I used to install on my computer. Once the OS was installed, all I did was download/install QuickTime and Second Life, and everything seems perfect in the Virtual Machine. With that being said, any suggestions as to what specifically could be causing it hardware wise? Maybe a BIOS setting of some sort?

Yea, I think I've seen that link posted in a few spots, and I've done those as well. I actually just now finished reinstalling the OS, and it's still happening. I've installed SL many of times, and this is the first time I've ran into this. I wonder if it's something hardware specific.

I've downloaded and installed Second Life 2.7.2 on my brand new Windows 7 x64 machine. Whenever I start up SL, I get an error saying the media_plugin_webkit failed. Searching google and several forums, I've done everything I've seen suggested which includes... Updating Windows Update Completely Un/Reinstalling SL Un/Reinstalling QuickTime Un/Reinstalling Safari Un/Reinstalling Flash (IE/All Browsers) Disabling Windows Firewall Disabling Windows Defender Disabling AVG Antivirus Manually Installing VC2005 Redistributables Manually Installing VC2008 Redistributables If anyone has ANY other suggestions, I'm all ears.
