AIM v UAC: It Works!
Instead of updating an old blog post, I decided to write a new post regarding the steps outlined in resolving an issue with the error "Server Execution Failed" in Vista. Before I start, I think it would be best to mention that when I was having this issue, I had trouble accessing Google Desktop's Options page. As many would know, the Options page pointed to the localhost. It would take about 3-5 minutes before the page loads and another 3-5 minutes to save the changes. I tried reinstalling Google Desktop thinking it was just a bad installation. That was before I found the article suspecting of UAC being turned off when installing AIM that caused this issue. I would've followed the steps to the letter, but I thought this might happen again if I did this in normal mode. I decided to boot first in Safe Mode, and do all I need to do from there. Better safe than sorry.
Upon booting in Safe Mode, I then proceeded to uninstall AIM by going to the Control Panel. Successfully uninstalling it, I re-activated User Account Control and then rebooted Windows normally. When it's all up and running, I noticed that suddenly, the red "X" from the network icon was gone and that there were no more network errors. I didn't try accessing Google Desktop's Options page yet and chose to reinstall AIM with UAC turned on. Agreeing to the prompts, the install went without hitting any snags. I checked the network icon and it is still the nice and functioning one, no Xs. I then tried accessing Google Desktop's Options page and it loaded up (almost) instantaneously. Everything seemed to be working normally.
Another one of the symptoms I noticed when I got this issue was that there was no audio present when using Windows Media Player and Quicktime. It's not conclusive if the cause was UAC or AIM because up until that time, I haven't used Windows Media Player. I tried reinstalling the Sound drivers but it it still not working. Although I can hear the Windows beeps and dings whenever a notification message pops-up, which leads me to think that Windows Media Player needs to be reinstalled. VLC media player was working fine, though, so I decided to use it as the default media player.
For now, BlueBox is working, but if I don't get Windows Media Player working fine, as it should, I'm going to reinstall everything again. Soon as I have the free time, that is.
UPDATE:
Upon downloading and installing the Vista Codec package, the issue with Windows Media Player is fixed, so it's most likely a codec problem. However, Quicktime still can not play DivX encoded videos. I think it would only be a waste of time to pursue a resolution for this issue as Quicktime wouldn't be my choice in playing videos other than MOV files. So yeah, this issue is fixed.
