Do I have to uninstall iTunes before installing Windows 8.1?

If this is an update from Windows 8 then you should be OK although you should backup your library regularly regardless.

Uninstall your existing copy of iTunes. Delete any copies of the iTunesSetup.exe (or iTunes64Setup.exe) installer files from your downloads areas for your web browsers and download a fresh copy of the iTunes installer from the Apple website:
http://www.apple.com/itunes/download/
(The current build of the 11.1.4.62 installer was changed a few days ago, which fixed the bulk of the reports of MSVCR80.dll/R6034/APSDaemon.exe/Error-7/AMDS-could-not-start trouble ... but the build number on the installer was not changed. So we're trying to make sure you do the reinstall using a "new good" 11.1.4.62 installer instead of an "old bad".)
Does the install with the new copy of the installer go through properly? If so, does that clear up the error message?
If you still have the same error messages cropping up, then try the procedures from the following user tip:

Do i have to uninstall cs3 before installing lightroom5?

just the question

There is no need to uninstall CS3. LR5 will recognize that you already have a version of Photoshop installed. But CS3 has an older camera raw plug-in. You will simply get a warning whenever you choose Edit In CS3 from Lightroom. As long as you let Lightroom render the copy being sent to CS3, there should be no problem and it will contain all of the develop settings from LR5. Click on the Open Image button to go straight into the Photoshop CS3 editor. On the first warning about camera raw incompatibility you can choose “do not show again” Just don’t click on Open Anyway otherwise it will open in the older version of camera raw contained in CS3.

I am running CS4 and want to run the trial version of CC to see if I want to begin a contract with Adobe. Do I have to uninstall CS4 before installing CC?

I have a lot of CS4 files on my system and don't want to loose them if I upgrade to CC trail version. I am NOT a heavy user but use it consistently through out the year to do promotion for my small business. If I decide NOT to continue with CC can I get bact to CS4?

Hi J-marshall,
You can have 2 versions installed aside of each other. Bot programs have their own folders. The files from CS4 can be read by the CC version. The other way around does not work for most file types. For example InDesign. To save for an older version is documented for most programs.
After CC trial / subscription removal the CS4 will stay on the system and works without issue.

First of all, why did you say yes to Nero Back up before researching what it does with files already on the HDD? When I install Nero, the Back Up is the first thing I disable, it is a nagging pain, there are much better backup programs available. There are several file recovery programs out there to recover deleted files, that is, if that is what happened. Also, if you haven't overwritten the files, so you should be able to find them.

I have a new iTouch. I'm having trouble downloading iTunes. I keep getting the error message: "Apple Application Software was not found. Apple application support is required to run iTunesHelper. Please uninstall iTunes, then install iTunes again. Error 2." I have uninstalled and tried installing again and get the same error message. What do i need to do?
Lg

Install 7-Zip (free), or a free trial of WinRAR, and use one of them to extract the contents of the iTunesSetup.exe or iTunesSetup64.exe installer file, then try installing AppleApplicationSupport.msi as a standalone component. Even if it won't install you may get a more useful error message as to why not.

Do I have to uninstall itunes on my old PC before importing/populating my Mac Book Pro with My iPad stuff?

Good Day,
My apologies for the cumbersome subject line/question. In a nut shell, I currently, have my itunes account on my spouses PC and on my iPad(3). I love the Mac stuff so much that recently, I purchased a Mac Book Pro so I could work from two Mac products. I want to take all the apps that I purchased, music, photos etcetera that is on my ipad and put it on to my Mac Book, but it is my understanding that I can only have my music and purchased apps or itunes account on two procducts that includes a PC. So my first question is do I have to, uninstall the itunes on my spouses PC before I can synch my iPad to the Mac, keeping in mind that the itunes account is in my name.
Second, do you have any tips (best practices, pitfalls to look out for) for the best way to populate my Mac Book Pro with my iPad Apps and Music, I would like the apps and music to be on both the mac book and the iPad. I realize the most obvious answer to my second question is synching the iPad with my Mac but before I do that I would be greatful for any insight and expertise in this area.
Thanks so much for you time.
L.

No you do not have to uninstall iTunes on the PC in order to unsync with the Mac. And where you got that information about having iTunes content on two products only is beyond me. You can associate your Apple ID and iTunes content with up to 10 devices but no more than 5 devices can be computers.
If you could copy the iTunes library to your new Mac, that would be the ideal thing to do in order to transfer the iTunes library over. That would make the process pretty easy. You can also download most purchased content again as long as you use the same Apple ID and you could move content into your iTunes library that way.
You will need to authorize the new Mac for your iTunes content. Launch iTunes on the Mac and got to Store>authorize this computer.
There are many articles that will guide you through copying the iTunes library to the Mac and you can look through a bunch of them here.

If you need to download past purchase ....

And this is a very informative user tip that will tell you how to move all of your iPad contents into the Mac if you cannot copy and transfer the iTunes library.

Itunes has Stopped working - I have tried uninstalling and re-installing - I am at wits end

I keep getting the message iTunes has stopped working. I have tried uninstalling and re-installing iTunes many times. I had contacted Apple at one point and they told me that I needed to uninstall items in the following order iTunes, QuickTime, Apple Software Update, Apple Mobile Device Support, Bonjour and then Apple Application Support. I have done this numerous times. Can anyone help or offer suggestions. Using Windows Vista Home Premium SP2. Thanks.

StackHash error has something to do with VISTA's DEP (Data Execution Prevention)
I managed to get something online from Tech expert and hope this will resolve your issue. Good Luck!!
The StackHash error happens any time DEP is found that there is an issue with the program run. The error is related to Data Execution Prevention. Here’s how 99 percent of Vista and Win7 users can fix a StackHash failure:
Click the run button and open the Control Panel
Browse to the section of System Maintenance then to the System
At the left side, select Advanced System Settings link
In the System Properties Window the top section is named as Performance with the Settings button. Click this button.
Choose the Data Execution Prevention tab.
Select the option which reads Turn on DEP for all programs and services except those I select.
Use the Browse button to locate the executable file for the application you were trying to start when you received the StackHash error, and click Open to add it to your exceptions list.
Click Apply or OK to commit your changes.
Note: Nobody can guarantied you that described instruction will solve the 100% of the StackHash error issues but you can try it to resolve the problem.

Downloaded Itunes to Windows 8. When opening Itunes error message 'Apple Application Support is required to run ITunes. Please uninstall Itunes, then install ITunes again.' I have uninstalled and reinstalled still same error received.

I downloaded ITunes onto my computer with Windows 8. Each time I try to open it I get the same error of "Apple Application Support was not found. Apple Application Support is reuired to run iTues. Please uninstall ITunes, then install ITunes again. Error 2 (Windows error 2)". I have tried uninstalling it and reinstalling it multiple times and continue to get the same error. I am unsure of how to fix this.

Let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you? If so, does iTunes launch properly now?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)

HT2292 I cannot access the iTunes store on my desktop. (brand new) I can access iTunes store on my laptop, so account is fine. When I go to sign in iTunes just says "Accessing iTunes Store" indefinitely. Have totally uninstalled and re-installed twice.

Close your iTunes,
Go to command Prompt -
(Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
(Win XP SP2 n above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
In the "Command Prompt" screen, type in
netsh winsock reset
Hit "ENTER" key
Restart your computer.
If you do get a prompt after restart windows to remap LSP, just click NO.
Now launch your iTunes and see if it is working now.
If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:

I have tried uninstalling and re-installing iTunes and my pc still will not connect with the iTunes Store. I have tried just about every suggestion on the web to no avail, please help.

When I click on the store it just never opens, I do not receive any message. I try to "refresh the page" and nothing. While having the store selected I go to "help" and check for updates and i get a message; "The iTunes updatte server could not be contacted" and it prompts me to check my internet connection which is fine. None of the items under the "Store" respond with anything.
I ran a iTunes Diagnostics/ Under "Which Tests do you want to run" I check only "Network Connections" and the results that I receive is...
Network connectivity:
     Network interfaces, verified
iTunes Store connectivity:
     Internet connection, verified
     Secure link to iTunes Store, FAILED

Apple Application Support was not found. Apple Application Support is required to run iTunes. Please uninstall iTunes, then install iTunes again.

I need help! I got my new iPod and I need to install iTunes on my laptop because I didn't have it before. I install it and I go to open it and it says "Apple Application Support was not found. Apple Application Support is required to run iTunes. Please uninstall iTunes, then install iTunes again." I've done that three times and it does the same thing... WHAT DO I DO???

Let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.

I have been using itunes on my windows based pc for years but since installing the latest itunes update I have been getting the error message A required itunes component is not installed. Please reinstall itunes. (-42404)

I have been using itunes on my windows 64 bit laptop for years but since downloading the latest itunes 10.7 update whenever I opened itunes the error message 'A required itunes component is not installed. Please reinstall itunes (-42404)'
Itunes would still load and play music in my library and I could still sync my ipod but when loading a CD itunes would not recognise the album/tracks and I would need to type them manualing after uploading.
I have just bought the new iphone5 and went to sync the phone with itunes. itunes recognises the iphone when plugged in via the usb port or when wi fi is turned on but itunes will not allow the phone to sync.
I spent over an hour the other morning speaking to apple customer support and have ensured I have administer right and that UAC is turned off.
I was taken through msconfigure and adjusted the startup tab but still no joy.
In the end I was e-mailed instructions on how to uninstall and then reinstall itunes and component parts.
Now that I've uninstalled itunes when I try reinstalling I get the following messages during the download.
The 1st message is;
'The installer has insufficient privileges to modify this file C:\Program Files (x86)\Common Files\Apple\Apple Application Support\Web kit.resources\inspector\Images\Spinner Inactive Selected.gif.'
When I click ok the next message that appears sometime later during the install is;
Service 'Apple Mobile Device' (Apple Mobile Device) Failed to start Verify that you have sufficient privileges to start system services.
The options I have are to abort, retry or ignore. If I retry the same message comes back and if I abort or ignore the download continues and I then get the following message:
'Apple Application Support was not found. Apple Application Support is required to run itunes Helper. Please uninstall itunes, then reinstall itunes again. Error 2'
After attempting to reinstall itunes only some components were installed however itunes would not open.
It would appear many people have experienced problems with this latest download!

'The installer has insufficient privileges to modify this file C:\Program Files (x86)\Common Files\Apple\Apple Application Support\Web kit.resources\inspector\Images\Spinner Inactive Selected.gif.'
That one's consistent with disk/file damage. The first thing I'd try with that is running a disk check (chkdsk) over your C drive.
XP instructions in the following document: How to perform disk error checking in Windows XP
Vista instructions in the following document: Check your hard disk for errors
Windows 7 instructions in the following document: How to use CHKDSK (Check Disk)
Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors, or use chkdsk /r (depending on which way you decide to go about doing this). You'll almost certainly have to schedule the chkdsk to run on startup. The scan should take quite a while ... if it quits after a few minutes or seconds, something's interfering with the scan.
Does the chkdsk find/repair any damage? If so, can you get an install to go through properly afterwards?
