ITunes won't run on Windows 7: Quicktime not found. .. But Quicktime works!

Installed latest version of iTunes 10 on a Windows 7 64-bit PC. Occasionally iTunes runs, but usually it gives the error: "Quicktime was not found. Quicktime is required to run iTunes. Please uninstall iTunes, then install iTunes again".
I have done this about 3 times, making sure to uninstall everything apple (itunes, quicktime, bonjour, etc.) Once I even followed a recommendation to delete all application data and reinstall. Rebooting, etc.
Quicktime runs absolutely fine.
I even tried repairing quicktime, installing quicktime by itself after iTunes was installed. No luck. Any ideas???

I've downloaded the iTunes installation file and tried to install or repair 3 times but keep getting a message that a required component is not installed (-45075).
Just in case the component being referenced is not part of iTunes but is rather part of one of the other related programs, it might be worth trying a complete uninstall/reinstall of iTunes and related componentry, as per the following troubleshooting document:
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8

ITunes won't run - invisible window where iTunes should be, but it never launches.

I'm running Windows Vista 32 (I know, I should upgrade) and over the last few weeks, I noticed that my podcast wasn't downloading new eps. Now, iTunes won't run at all.
I've done a full scan of the PC and there are no viruses found. I'm using Kaspersky.
I've un-installed all Apple apps and rebooted before trying to reload iTunes and it never runs.
Anyone have any idea what might be preventing iTunes from running?
I have a Windows 7 PC on the other desk, connected through the same switch and Cable Modem and iTunes is running fine on it, so it's not network / internet related, as far as I can tell.
Thank you,

"The feature that you are trying to use is on a network resource that is unavailable. Click OK to try again or enter an alternate path to another folder containing the installation package iTunes.msi in the box below"
Let's just run through the standard procedures for that one again, just to be sure.
first, head into your Add/Remove programs and uninstall your QuickTime. if it goes, good. if it doesn't, we'll just attend to it when we attend to itunes.
next, download and install the Windows Installer CleanUp utility. Then use it to clear any existing itunes and/or QuickTime installation configuration information from the PC. (Launch CleanUp, find any iTunes and/or QuickTime entries in the list of programs in CleanUp, and remove those entries.)
Description of the Windows Installer CleanUp Utility
next, use the the following document as a guide for manual removal of leftover itunes and quicktime program files:
Removing iTunes and QuickTime for Windows
now try another itunes install. does it go through properly this time?
(If any step of this procedure failed to work, explain to us as best you can what the problem was.)

When I click on iTunes it says QuickTime not found

After I got a movie file from a friend (and a player), everytime I tried going on iTunes it would say "QuickTime not found. QuickTime is required to run iTunes. Please reinstall iTunes."
So I uninstalled iTunes and redownloaded the set up and installed iTunes. It's still saying the same thing. What is wrong?

It might be worth trying a complete removal of iTunes and Quicktime followed by a phased reinstall.
Download a fresh copy of iTunes and also the version of QUicktime that does not include iTunes (it is not the defualt option):

http://www.apple.com/itunes/download/
Use the following method to remove iTunes and QUicktime etc:

Vista

Restart your computer.
Install Quicktime and check to see it works.
If it does, install iTunes.

Not using Boot Camp, but you should be able to using virtualization software such as Parallels to run Windows concurrently with OS X.

With Windows 7 Home Premium, whenever I start iTunes, I get a message that colors have been reverted to Windows Basic because iTunes won't support my Windows Aero configuration. Is there a fix for the incompatibility?

With Windows 7 Home Premium, whenever I start iTunes, I get a message that colors have been reverted to Windows Basic because iTunes won't support my Windows Aero configuration. Is there a fix for the incompatibility? I don't mind the color changes, but I'm having an external speaker problem that could be related to the incompatibility (at random times--usually several hours after start-up, my external speakers--connected via my Samsung Central Station's wireless docking station and computer-installed dongle--shut off and won't play until I restart. I've investigated other options, but iTunes may be the problem.) Thanks.

Perhaps let's first try updating your Apple Software Update.
Launch Apple Software Update ("Start > All Programs > Apple Software Update"). Does it launch and offer you a newer version of Apple Software Update? If so, choose to install just that update to Apple Software Update. (Deselect any other software offered at the same time.)
If the ASU update goes through okay, try another iTunes install. Does it go through without the errors this time?

Hi, I have adobe acrobat 6.0 but it won't run on windows 7, is there an update availabe?

I agree with Doc, but there may be a work around. Actually, your best solution is to just buy AA XI. The work around depends on what you mean by does not work. Do Acrobat and Distiller both install and appear to function? Is the problem one of not being able to print? If both of these answers are yes, then you can install an independent PS printer (maybe one from Adobe or one of the HP color PS printers), change the name to Adobe PDF for your use (not required), and change the port to FILE. Then to create a PDF you would print to that printer and open the file created in Distiller to create a PDF file. May or may not work. However, AA6 is so old, it is likely to cause other problems, even if this process works. If nothing else, it will not open some of the newer PDFs that are being created today (at least I would guess that will be the case). So buying XI is really in order.
Other issues that may crop up will be activation (will likely fail) and updates that have to be obtained from the FTP site and not the web.

HP Utility won't run in Windows 7

The HP Utility application for an HP Designjet Z3200 won't run in Windows 7. I browse to the application and nothing happens when I try to open it. I've rebotted several times as well as uninstalled and reinstalled the latest version of the app downloaded from HP.
Anyone have any clues as to why this is happening?

Itunes won't run after download

itunes won't run after download. simply asks to acknowledge agreement which I did. help

You appear to be able to backup your contacts without iTunes. Google "backup iphone contacts without itunes".
The way to avoid having to get a tech person in is to get past the idea that your problem (which you still haven't defined) is "beyond my ability to fix". ;-)

TS1717 iTunes won't open on Windows 7

iTunes won't open on Windows 7.
Error message says MSVCR80.dll is missing.
Re-installing iTunes over the top didn't work, it couldn't get passsed a mobile devices error. Any thoughts anyone?

Howdy rtih,
It sounds like you are unable to open iTunes after a recent update. I suggest the troubleshooting steps from the article named:
iTunes 11.1.4 for Windows: Unable to install or open
http://support.apple.com/kb/TS5376
Check for .dll files
Go to C:\Program Files (x86)\iTunes and C:\Program Files\iTunes and look for .dll files.
If you find QTMovie.DLL, or any other .dll files, move them to the desktop.
Reboot your computer.
Note: Depending on your operating system, you may only have one of the listed paths.
Uninstall and reinstall iTunes
Uninstall iTunes and all of its related components.
Reboot your computer. If you can't uninstall a piece of Apple software, try using the Microsoft Program Install and Uninstall Utility.
Re-download and reinstall iTunes 11.1.4.
Thank you for using Apple Support Communities.
All the best,
Sterling

ITunes 11.2.2 for Windows x64 will not successfully install. Removed prior iTunes, and still will not install. 10.7 installs just fine, but constantly asks to upgrade to 11.2.2. Any Thoughts?

iTunes 11.2.2 for Windows x64 will not successfully install. Removed prior iTunes, and still will not install. 10.7 installs just fine, but constantly asks to upgrade to 11.2.2. Any Thoughts?

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
The section Install missing components has advice on breaking down the iTunes installer into the individual .msi files which might prove useful if one component won't install normally.
If needs be, the Microsoft Program Install and Uninstall Utility (MS Installer "Fixit") may be able to help force through the installation.

Quicktime not found message when starting Itunes

I've been using Itunes for a few years now, and recently I noticed a problem. Now every time I try to open Itunes it tells me quicktime was not found, and to reinstall Itunes. I have reinstalled both Itunes and Quicktime several times, and with each attempt I reccieve the same quicktime not found message. If anyone has any idea how to correct this problem, please post your responses. Thank you. Oh, and if it makes any influence whatsoever, I have windows xp
thank you!
