ITunes 10.5 will not install correctly

Question

So iTunes decides not to install correctly now that 10.5 comes out.  I'm unable to update my iPhone 4 to iOS5 and it's seriously ******* me off.  I've tried nearly everything and nothing has come close.  Right now the errors that I am getting are "Apple Application Support was not found.  Apple Application Support is required to run iTunes.  Please uninstall iTunes, then install iTunes again.  Error 2 (Windows error 2)".  I've uninstalled and reinstalled iTunes about 50 times and that's not a joke, and I've also restarted my computer about the same amount of times.  I've been searching the internet since the update came out and have tried every possibility and suggestion that people have said from people who have had the same trouble in the past.  I don't know what to do.

My apologies everyone for the spelling errors in my previous post as I have a horrible habit of not doing spell check . So heres a better and hopefully less spelling mistaken riddled version hahaha...Hello All, Well I too was having a **** of a time upgrading my Itunes to 10.5 version on my Dell XPS Windows 7 64 bit laptop so that I could update my Iphone 3 GS. Ihave tried so many things (except for the kitchen sink) in the past 8 days my head is still spinning hahaha since IOS 5 was released to no avail...that is until today. So all you Windows 7 64 bit laptop users, sit up and listen carefully ( as my desktop had no issues updating to Itunes 10.5 forsome reason?, I willl try to figure that one out later) So what I did today was I downloaded the new Itunes 10.5 Windows 64 bit version (68MB I believe) and saved it to my HD. I then proceeded to CNET and downloaded a nifty and very excellent little program called Revo Uninstaller 1.93 (free version). So here's the steps to follow as to what I did and it worked flawlessly without even doing a restart of my system, As follows now OK: 1:) Download Revo Unistaller 1.93, 2:) Run the Revo exe file and then open it. It will then open a window and populate it with all the programs installed on your Windows 7 device. 3:) Look for the program icon called Apple Software Update and click on it, it will then highlight. 4:) Then at the top of the window of the Revo Unstaller program you will see an icon called uninstall with an X on it, click on that it will do a deep registry uninstall of ALL the Apple Update Software program with a 4 step instruction, follow those instructions. 5:) Then after the program runs another window will show a bunch of programs with some registry trees which are bolded. Check mark those bolded ones and select the delete button in the Revo Uninstaller window (lower right hand corner). After you are finished close the Revo Uninstaller program. 6:) Now go find your Itunes 10.5 exe file that you saved on your HD and run it, then presto...you should have Itunes10.5 loaded onto your Windows 7 device. Now plug in your Iphone (3 GS or later only) and or Ipad and it will automatically sync say that there is an update for your device. Follow the usual steps from there. It worked for me so let me know if this works for all you other WIndows 7 64 bit laptop users that were having these same issue as Dirky3301 and I were. As for me, I am now happier than a pigin s**t. Thanks everyone for reading this as I hope this wasn't to boring or to indepth? Off to play some RAGE now on my laptop hahahaha.
