    An error occurred during installation of assembly component

    Hello Everybody,

    I've been having the same problem for a very long time. I'm trying to install iTunes for my iPod, but these messages keep on coming up and cancelling the installation:

    - The Windows Installer Service could not be accessed (somehow solved today)
    - 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 managed to solve this)
    - An error occurred during installation assembly component. <-- this is my problem. I don't know how long I'm already looking for a solution for this problem, but nothing seems to work. I have already done a full virus- and anti-malware scan.

    So I was hoping that you guys would come with the solution for my problem?

    Kind Regards,
    VistaExplorer

    P.S. I tried to copy iTunes from my brother on a USB-stick to my laptop, but that doesn't help either.

    here's one possibility- Office 2010 wont install keep Getting Error 2908 then 1935

    Note that if you have .net framework 3.5 or 4 shown as installed in Control Panel, you can choose to uninstall them. When you do, you will be given the option to Repair them. If so, run the repair.

    Again, this is just a possibility.

    Thanks for you answer. So do you think that I should uninstall .net framework 3.5 or 4, and replace it with .net framework 2?

    BTW, in my control panel it says that .net framework 3.5 SP1 is installed, and .net framework 4 Client Profile as well :S

    No. You don't want to uninstall 3.5 and 4. In addition, I believe 3.5 uses 2.

    In control panel, click on the 3.5 entry and then uninstall, you should get two options. Select the Repair option. Do the same for 4.0.

    So I selected the repair option, I had to restart my computer, and ran the iTunes-Installer again, but the same message came again

    Is there any other idea that might help?

    Just wonder- you're trying to install the itunes software. Is it written for Windows or MaC?

    It is for Windows XP, Vista and Windows 7.

    Are you using the 64 bit version of iTunes? Supposedly this is a forum for 64 bit versions. There is a 32 bit and 64 bit version.

    Have you tried "run as administrator".

    I am using the 32 bit version of the installer, but it doesn't help. Running as administrator doesn't change anything either.

    I assume you're using the 32 bit installer because you have 32 bit Vista.

    You could try disabling anti-virus and it's security features. You could also try turning off User Access Control and, possibly, Windows Defender.
