itunes will not install on my Dell Inspiron laptop, OS Windows Home Premium 64 bit... I continue to get an error window informing me that the installer package is missing a dll...?!
iPhone 4S, Windows 7
That's a bit rarer. It's a 1723 error message. (1721 and 1722 are more common.)
Even though the following user tip is about slightly different errors (the 1721 and 1722), perhaps try it with your one too:
This is a first time installation, therefore this suggestion does not work... When I click the install, it appears to begin to unpack, then it quickly fails presenting the pop-up error indicating a missing dll...?!
No working solution posted yet on this topic. I have the same problem. WHat I've tried is running fix it from WIndows support, but this doesn't help. Still looking for a solution.
It's somewhat comforting to know I'm not the only one having this problem; hopefully a solution will come soon? I haven't stopped here, I've got technicians working on a solution as we speak! 😀
Can you please give the name of the dll library that is missing.
This will help to resolve the issue.
@tzbikowski: that would be too easy. No, unfortunately, the error message does not mention a specific dll.
it looks like it fails on iCloud control panel installation rather than iTunes.
Can you untick iCloud during initial install and see if iTunes install goes through?
My problem involves my attempt to install iTunes, Quicktime and Realplayer...
OK, on reading it again the dll may be there but cannot be run.
Did you try to right click on the installer and Run as Administrator?
Yes, that's the trick! Thanks! Feel like an idiot I didn't think of this myself.
Run as Administrator works perfectly!
I have been running into this problem for years, but it's on a secondary laptop, and I'd just given up on Apple products on the thing once I was stuck on this problem for quite awhile. I got curious again, though, and once I encountered the error again, I started methodically uninstalling all the Apple software on the machine, expecting to install them all again afterward. I was able to uninstall iTunes, Quicktime, Apple App Support (I think), and Device Support. When I tried to uninstall Apple Software Update, I ran into the error as well. After trying a lot of combinations and fishing through other related threads, I have gotten to an understandable state, though I don't know the answer.
After downloading the most current iTunesSetup and pulling it apart with WinRAR, I tried to manually install just the Apple Software Update msi, and encountered the dialog:
There is a problem with this Windows Installer package. A DLL required for the install to complete could not be run. Contact your support personnel or package vendor.
Down inside the TEMP directory, however, is a MSI log file with the above text PLUS the following:
Action UnscheduleASUChecks, entry: UnscheduleASUChecks, library: C:\Windows\Installer\MSI8F3E.tmp.
The status in the installer reads: Status: Unscheduliing Apple Software Update
So, the problem seems to involve removing the periodic software update check from the Windows scheduler. Any idea how to get past this stumbling block?
Windows installer missing dll
