Oh, even the installer clean up utility gives you that message? Let me go ask my installer expert. Because there's a manual way to remove the iTunes uninstaller from the registry, but I forget the secret GUID to look for.
I get distracted, so bump this thread if I don't get back to you.
To update Roy got back to me and said it wouldn't instal because one of the keys in the regedit program was pointing to drive F, instead of pointing to my documents. Trouble is i've changed that now and it's not made one iota of difference 😟
First off, I'm probably one of the least tech-savvy people in this forum. This issue has been plaguing me for the past week with no end in sight. I hunted around the net trying to find a straight answer and finally I came across something that worked.
NOTE: I'm running Windows XP so I can only speak for my success in that regard.
1) Click the Windows Start button.
2) Select "Run". (A drop down entry box will appear.)
3) Type "regedit" (DISCLAIMER: Proceed at your own risk. Editing the registry can be dangerous and cause even more problems to your operating system if you don't know what your doing, like me. That being said this solution still seemed fairly low risk to me, I took a chance and it worked beautifully.
4) You will now see the "Registry Editor" window pop open with a directory of folders. In the menu along the top click: Edit\Find...
5) In the "Find What" box enter the name of the drive that was giving you the error message. In my case it was "F:\" but it could be different on yours. (Example: "G:\" or "L:\", whatever the letter is of your "Invalid Drive" message.
6) Click the "Find Next" button.
7) Results will appear in the window to the right if there are any hits.
8) Read each result carefully and decide if it seems like it should be there. If it's obviously obsolete or does not belong then select it and delete it.
a) In my case I found about a half dozen items. Two of them were outdated folder directories that no longer existed (I had changed the path name a long time ago), while the remaining hits were all "WDSynch" items (Western Digital external hard drive application. "Passport" or some nonsense.)
NOTE: I am very suspicious of external hard drives as one of the culprits of the iTunes installation problem (Invalid Drive *:\, particularly Western Digital's "WDSynch" application. Almost every post I've read the person mentioned something about their external hard drive so I'd consider that possibility first.
I had tried using this bloated, non-user friendly "WDSynch" and "Passport" application when I first bought my WD external hard drive and discovered that I hated it. Don't get me wrong, the drive itself is great but just avoid the synch app nonsense unless you want deal with constant stress and headaches (Yes, it's a very jaded and biased view so take it or leave it).
After discarding the unfriendly-ware I wound up reformatting the drive anyway from FAT32 to NTFS and I now just use a simple drag-and-drop system for file transfers and copying. (You can leave it at FAT32 if you want, I just didn't like the partition restrictions.)
9) Do multiple searches to make sure you find every last little bugger (F3 will find the next one) so on and so forth until all evidence of that drive letter is gone.
10 Exit the Registry Edit.
11) Reboot your machine.
12) Try running the iTunes install again and it should work!
Disclaimer: This is my own experience with this problem so don't blame me if you mess up your computer. I was at my wits end and had nothing to lose so I took a chance and it paid off.
You solved the problem by sending me to the registry. I found an F drive file that needed to be deleted. After that, iTunes (7.5) installed without any problem.
This may help too, although my error message read Invalid Drive E.
Here is one possible solution to the infamous “Invalid Drive: E:/” error that has plagued me while trying to upgrade to the latest version of Itunes.
Although I’ve found a couple of suggestions on other message boards on how to fix this problem (going to Control Panel, Administrative Tools and Disk Management), they never worked for me.
Let me first say that I use Windows XP Professional Version 2002 with Service Pack 2 and I also have an external hard drive that I connect to my computer with a USB cord. I use the external hard drive to store my Itunes library on.
My advice to anyone who has received the Invalid Drive E error message, start plugging in any devices that you may have connected to your computer at one time or another. It could be your camera, a flash drive, Ipod or an external hard drive. As soon as you plug it in, your computer will let you know which drive it is called. Keep it plugged in, turned on, download Itunes, and change the location where you want the Itunes file stored.
When downloading the file, another window will pop up, I believe it was the Installer window, asking where you want to save the Itunes file. And there at the bottom of the box it will show, download to Drive E:/Ipod (that's what mine read) or change location. I changed the location to my C drive Program Files which is where I normally keep my files. I was finally able to download the latest version.
Here's what you do:
1. Go to Start> Control Panel> Administrative Tools
2. Next double click Computer Management icon
3. Click on the Disk Management on the left
4.Right click a disk other than your system drive (i.e. a CD drive) and select Change Drive Letter and Paths
5.Click change drive letter
6.Select a new letter (whichever one iTunes is griping about)
Try reinstalling again
