Save the installer complete your computer somewhere. Open your
file browser. Go to the folder of the computer program. Search all Mozilla
and Firefox files. Rename them by adding .old to them. Restart
the computer again. Now, try the full installer.

Will make cela a try and report.

  • Get 'no scanners were detected. If a scanner is installed, make sure that it is turned on and connected to the computer and try again. "

    Original title: Windows Fax & Scan

    Hello, I just bought a new printer (Canon MG2450), and every time I try to scan something an error comes out.

    The error that says:

    No scanners were detected. If a scanner is installed, make sure that it is turned on and connected to the computer and try again. For more information about adding or troubleshooting scanners, see Help and Support.

    the printer is powered on and connected. I tried searching the Internet and I tried the TWAIN_32 and everything is good.

    What can I do?

    Daniel Capelle

    The scanner came with a CD to install the software?  Some more recent does not come with a CD, you must go to the Canon Website and you get the software.

    I'm trying to install Microsoft FreeLancer on Windows 7 64 bit Home Premium edition (according to WinVer: Version 6.1, build 6701, Service Pack 1).

    After inserting the DVD in the drive and run "Setup.exe", I am invited by the UAC to elevate permissions - who I am agreement - then the following error message appears: "Setup was unable to find (or could not read) the language specific setup resource dll, unable to continue."

    • I checked the DVD is in good condition, even with regard to the attempts to install from the disc to a friend and even went up to compare the MD5 of all files on two DVDs, the checksums match.
    • I tried using the compatibility mode for XP, although according to the report of another user on the statements of the Windows Compatibility Center that this should not be necessary.
    • I ran a full "chkdsk" (i.e. one scheduled for after a reboot, rebooted) and chkdsk reported no error.
    • I deleted all files "di - use ' %TEMP%, immediately after the restart and before you run setup.exe.

    Everything I try seems to have no effect on the resolution of this problem.

    I managed to work around this problem by using the following workaround solution:

    I installed Freelancer CD on a Windows XP virtual machine running in VMWare Workstation. I then moved the installation directory (C:\Program Files\FreeLancer) off the coast of the virtual machine on my Windows 7 computer in (C:\Program Files (x 86) \FreeLancer).

    The game seems to work fine as long as it is run with administrative privileges (that is, the freelancer.exe running). Without administrator rights, the games is never recorded. With them, they are registered under "C:\Program Files (x 86) \FreeLancer\EXE\Accts\SinglePlayer" successfully.

  • How can I make sure that there are no other programs running when I try to install another program?

    I keep trying to install a program, and it will not be installed.  It is said that there are other programs that run in the background.

    The best way to see what's running is press ctrl + alt + delete at the same time and open the Task Manager. Then under the applications tabs, it will show you all the programs that are running. You can click and close the program from here. If it is empty, then the problem is most likely a program process that is running. On the tabs in process, you can find the process that is running and the origin of the problem. You can click on the program here and so close. I hope this helps. If this isn't the case, you could let us know what kind of program you want to install.

    You may have to disable ZoneAlarm ForceField to be able to install Firefox.

    If you use ZoneAlarm Extreme Security then disable virtualization and reinstall Firefox.
    Other security software may have similar characteristics to prevent Firefox update files correctly.

  • During the installation of the ultimate upgrade, get "one or several components of the system could not be configured", then it restarts and pours me to premium.___How can I say what is the cause of the problem and fix it?

    I have the same problem as Laweaver.
    I have a HP pavillion Model # m9040n running the 32-bit version with service pack 1.
    My Vista Ultimate Upgrade drive is 32 bit and also has Service Pack 1 on it.
    I ran my system through the Microsoft Update and it is common.
    I ran Vista Advisor and he tells me that everything is good to go.
    I also ran my system through the center of update of HP and he is current.
    I tried the Ultimate Upgrade three times and got the same message twice.
    Of course, it waits until it reaches "end of the upgrade" before it fails.
    I turned all the extra wide including the firewall when I tried the upgrades
    My computer came with the home edition Premium already installed on it and I have the disks of backup for him if I have to do a repair on it.
    I have the same question though - how to tell what the cause of the problem and fix?
