Error 1721.There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor.
I have tried for two days every single solution that has been given on the internet but nothing works. I have a Acer Aspire 7735Z with Windows home premium. 32 bit. Service pack 2 is installed. The error keeps coming back when I try to install iTunes. It did work previously but for some reason it stopped. The error effects the reconizing of the iPod in iTunes. iTunes is installed but now when I try to open it hte following message appears:
the software required for communicating with ipods and mobile phones was not installed correctly. Do you want iTunes to repair this for you. Click yes, then the next message appers:
the software required for communicating with ipods and mobile phones could not be repaired. I have reinstalled iTunes, Quick time player. Did all the steps that Microsoft or Itunes asked me to do. Even went in to the Commant Prompt. Went for Check disc ect. Installed a earlier edition of iTunes. But it all keeps coming back to the same problem: error 1721. Any ideas??
I have installed the same iTunes on another pc and connected the iPod and that worked ok. So it is not the iPod or the software for iTunes..

Hi M.kobessen,
1. Does this issue occur while installing all the programs or only with iTunes?
First you may try the steps provided in the below link.
Method 1:
Start the Windows Installer service
a. Click Start, type Services.msc and press
b. Double-click Windows Installer
c. Set the Startup type of Windows Installer to Manual
d. Click Start to start the service. Note down the error message if any.
e. Click OK.
Method 2: Unregister and re-register the Windows Installer to do that follow the steps provided below.
a. Click Start, click Run, type MSIEXEC /UNREGISTER, and then click OK. Even if you do this correctly, it may look like nothing occurs.
b. Click Start, click Run, type MSIEXEC /REGSERVER, and then click OK. Even if you do this correctly, it may look like nothing occurs, or you may briefly see an hourglass. After you run this command, the operation is complete.
c. Try your Windows Installer-based application again.
Method 3:
Try performing SFC scan on the computer.
SFC /scannow is a super-useful command you can use in any Windows version. When the SFC (System File Checker) command is used with the /scannow switch, the tool will scan all of the important Windows files on your computer and replace them as necessary.
Missing and corrupt operating system files (like many DLL files) are arguably the biggest cause of major Windows issues. Considering that, plus the fact that SFC /scannow is completely automatic and very easy to use, the tool should usually be one of your first troubleshooting steps.
Refer:
How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7
http://support.microsoft.com/kb/929833
Once SFC scan is done, try and install iTunes in administrator mode.
To install in administrator mode,
1. Locate the program icon, right-click click Run as administrator.
Thanks and Regards:
