    Cannot install itunes for windows - error: Apple Application Support is required to run Itunes Helper. Uninstall and reinstall (as I did twice)

    For general advice, see troubleshooting problems with iTunes for Windows updates.

    The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach.

  • Cannot install updates for Windows 7 SP1

    Hello

    I tried for awhile now to switch to Windows 10 without luck ( http://answers.microsoft.com/en-us/windows/forum/windows_10-win_upgrade/windows-7-key-not-recognized/9a66ab9a-819a-4285-9461-64e7528db222?tm=1450545430339&auth=1 ). In the end, I decided to reinstall Windows 7 RTM, install all updates and then upgrade to Windows 10.

    Unfortunately, I seem to be impossible to install updates for Windows 7 now. Everything was going fine until Windows Update Agent 7.6.7600.320 installed. After a few mistakes, WU start looking for updates for hours. I've tried everything as suggested here without a bit of luck. In the end, I decided to leave it to search through the night and finally it does find and download updates about 300.

    Installation of these updates takes about 4 hours and Windows restarted and tried to configure the new updates, restarted saying once again he could not configure the updates of Windows and it will undo the changes. And it's been like that for over an hour.

    So as soon as now I can not even update Windows 7, not to mention the upgrade of Windows 10.  Any ideas? I'm sick of the Windows updates, causing problems.

    Installation sometimes loads of updates at a time can cause problems. When you access the list of the 300 updates Windows updates to odd day again, deselect all of them and then choose the oldest (for example) 50 and see if they install on their own.

    Sometimes do fall off a long list of updates and try to install more small pieces may help them to install.

    Is not sure, but its worth a try as a first shot.

    (I know what you mean though issues of update.) It makes you wonder what's going on sometimes :-()

    If this does not help, is there required failure account error codes?

    I think that the decision of the antivirus program is a personal opinion

    I put t like McAfee and Norton because they need a lot of system resources and do a slower computer.
    I prefer AntiVir and Kaspersky Security suite. The two programs have good scan engine and don t need a lot of system resources. They are easy to use to use it.
    AntiVir is free but it s just an antivirus. Kaspersky Security suite also contains a firewall, antispam filter and more.

    It s your choice what program you are using. ;)

  • Cannot install Games for Windows Live

    I need to install Games for Windows Live to play several games on this laptop.

    When I run gfwlivesetup, all downloads very well and gets to the point where it installs GFWL and I get the following error every time:

    "An error occurred during the installation of assembly ' Microsoft.VC90.CRT, version ="9.0.21022.8", publicKeyToken ="1fc8b3b9a1e18e3b"processorArchitecture ="x 86", type ="win32 "'. See Help and Support for more information. »

    Looking through several log files, I discovered the error to be (0x8007078f) code that relates to, "connection failed: the machine you log on is protected by an authentication firewall." The specified account is not allowed to authenticate on the machine. »

    So two things come to mind. The account is authenticated and firewall. Well, my account is an administrator account and right click on gfwlivesetup and choose "run as Administrator" does not change a thing. Well, screw the router, I just take the right out of my router modem jack and plug rather the ethernet of my laptop, without going through all the ports that can be blocked. The only firewall that is up and running (the only one installed) is the MS OS firewall, so let's just turn this baby off and still the same error.

    So if we ignore all the error code (0x8007078f) completely, then we can treat the error originally presented... I see basically: processorArchitecture = "x 86", type = "win32".

    Well, I'm running a Windows 7 64 - Bit, and my processor is a Core i7-740... I am out of the resources here. I have seen many people having the same problem or similar (Google reveals a lot). So if someone is willing to stick with me throughout this, I intend to see resolved (at least for me). I only pray that as I did not reinstall Win 7 or make repairs. They do not understand all of these DVDs with the laptop.

    Thanks in advance,

  • Cannot install addon off-site because "Firefox prevented this site asking you to install the software on your computer.

    I try to install GMail Watcher by Sonthakit. It is hosted off site here: https://sites.google.com/site/sonthakit/gmailwatcher

    Whenever I try to install the addon by clicking on 'Install the free', Firefox tells me "Firefox prevented this site asking you to install the software on your computer" and does not give me an option to ignore the warning and install it anyway. I clicked on the padlock icon in the address bar and activated all the appropriate permissions, but it will not yet let me install the addon even after restarting Firefox. I have just reset Firefox and use the latest version.

    How can I say grass and let me install the Firefox addon?

  • Portege Z830: Cannot install Win7, complains about driver CD/DVD

    Hello!

    I have a brand new Portege Z830 and as usual wanted to start by installing a new installation of Windows 7 x 64 (that I don't want the software provided and cannot be trusted, that it is safe in any case). I have saved all of the disk, prepared a flashdisk USB bootable with Windows Setup and it. The flashdisk OK boots, Windows wonder about my language and keyboard, and then shows a screen where I can choose between installation, repair and something else (the Recovery Console, I think).

    I click on install, Windows starts the installation program aand once a first dialog box appears, it displays an error message that basically says (this is a translation of the message from my localized Windows): "a required CD/DVD drive driver is missing. If you use a driver from the floppy disk, CD, DVD, or the flashdisk, insert now. "And I can't get over this error message. The strange thing is, there is no reason for that Windows requires no additional driver, because he can read the installation flashdisk (apparently) and he can see the ultrabook SSD, too (can be verified as well in the recovery console and clicking the browse of this dialog box). So far I have tried:

    (1) four different Windows 7 images (two of them to MSDN AA, two physical, that have been used successfully to install the OS before).

    (2) switch SATA mode to AHCI Compatible.

    (3) two different flashdisks.

    (4) any combination of the boot order.

    Nothing has worked. I even tried e-mailing of Toshiba, but all messages to return with 'user unknown' (understandable, I had to guess addresses since Toshiba doesn't seem to provide some official way to communicate with them - or is hiding if well I have found it). Does anyone have an idea what I can try next? I rather like the Z830 and I'd love to use it, but the ability to install my own installation of the operating system is essential for me.

    Thanks, Pepak

    > I tried e-mailing of Toshiba...
    Maybe stupid question now, but have you tried to contact Microsoft too? If the BIOS is OK, and if all the USB ports work correctly, I don t think it is Toshiba related issue. Toshiba offers notebook with the original recovery image (WIN7 64-BIT HOME PREMIUM) and ability to create bootable USB stick with the recovery image that can be used when you want.

    What you do now is your own installation of the OS. Toshiba has to do is to offer to all the important factors, download tools and utilities on the drivers page.

    What else could you try? Try to get external USB ODD and trying to install WIN7 using Microsoft installation disc. I'm sure it will work.

  • Cannot install drivers for Deskjet 3650 in Windows 7 XP

    I have a HP Deskjet 3650 which is connected through the USB port on my primary computer running Windows 7.  I can print without problem, I have problems sharing this printer with 2 other computers running Windows XP.  I downloaded the drivers for XP and excerpts on the Windows 7 computer.

    On the properties of the printer HP Deskjet 3600 series, I clicked on the sharing tab.

    Share this printer and rendering of printing on client computers are both checked.

    When I click on additional drivers, only X 64 is checked and said yes less installed.

    The two other options (Itanium and x 86) are both unchecked and say no less installed.

    I tried x 86 control and clicking on OK.  Then I am asked to install print drivers and browse to where are printer drivers.  I navigate to the 3600, enu, pilots, win2k_xp folder and see hpf3600k.inf when I click Open, then select OK, I get a selected printer driver not found error that indicates the specified location does not contain the driver for hp deskjet 3600 series (BOBO) on the architecture of processor required.

    On one of the XP machines, I installed the printer software and am not able to print if I physically plug the printer on it.

    On another XP machine, I have installed the printer software, but I download and extract the drivers.  When I click on the Add Printer Wizard and select the printer on the network, it tells me that I'm about to connect to a printer on the computer Windows 7 and says that it will automatically install a print on my machine driver.  I click Yes to allow him to continue and he told me that the server for the hp deskjet 3600 printer doesn't have the installed printer driver and I can click OK to search for the correct driver.  I click OK and navigate to the folder I extracted the drivers to and see that hpf3600k.inf is located in the folder and click OK and I get a window of driver error install that says that Windows cannot locate a suitable printer driver.  To help locate and install a suitable driver, contact your administrator.

    So, it seems to me that the driver that I downloaded on the site of hp for Windows XP is not the correct driver, am I wrong here?

    How can I get this printer to print on all 3 computers work without having to move from one to the other.  The printer must be physically connected to the Windows 7 computer, as the other 2 are in children's rooms.

    Try the following: on the machine XP go to the printers and Faxes folder, add a local printer, printer, create a Port, Local Port, \\Computername\Printername (use the name of the actual share of the shared computer and printer), OK, and then click disk and point to the directory where you unzipped the driver XP.

    On the XP machine, you have already installed the driver do the following: go to the printers and Faxes folder, right click on the Deskjet 3650, select Properties, Ports, the port, Local port Add, new Port, \\Computername\Printername (use the name of the shared computer and printer), OK.

    What should I do?... I checked the installation on other computers, and it works, it's just my computer I guess.

    Thanks in advance ():

    Click on the link below to view the titles of Need for Speed that show to be compatible with Windows 7. It may not be a list complete, so you need to check on the manufacturer's website.

    http://www.Microsoft.com/Windows/compatibility/Windows-7/en-us/search.aspx?l=en-us&type=software&s=need%20For%20Speed%3A%20Shift%202&page=1

    If it is not compatible, you can try and do a right click on the seutp.exe or .msi and select 'run as administrator '.

    If the program is not compatible, then you try to install and run the program in compatibility mode.
    Use the following steps:
    (1) right click on the program
    2) click Properties
    3) click on the Compatibility tab
    (4) select run this program in compatibility mode and select Windows Vista or other operating system, the program has been run successfully.

    Check out the link here: make sure to run older programs in this version of Windows
    http://Windows.Microsoft.com/en-us/Windows7/make-older-programs-run-in-this-version-of-Windows

    If you are running Windows 7 Professional or Ultimate version, install Windows Virtual PC and Windows XP mode (http://www.microsoft.com/windows/virtual-pc/default.aspx) and run your software in Windows XP.

    If you run Windows 7 Home Premium, you cannot run Windows XP mode, but you can try VirtualBox (www.virtualbox.org) or VMware Player (www.vmware.com), or any other 3rd party software virtualization and install a separate copy of Windows XP (family or professional edition) for this purpose. You can find the virtualization software free that will run on Windows 7 Home Premium.
