    Hi Can someone please HELP?
    I have a Windows 7 Acer Aspire 5750G Laptop. I installed a new Font that I inadvertently installed a toolbar with it. I can't remember the name of the programe, but when I tried to uninstall it, it wasnÂ’t there, so I tried to restore my laptop to an earlier date, now nothing works. All I get is The backup and restore application could not start due to an internal error: Class not registered (0X80040154). can someone help please.

    I use Google Chrome as my browser and Hotmail as my email.

    I have Avast, CCCleaner, and Spybot S-D.

    Since using my laptop to a previous restore point everything has gone wrong, I can't get into uninstall, I can't use my restore point, I can't use anything in My Control Panel. Network sharing will not open either.

    I have now bought an external Hard Drive. However, when I plugged it in I got the message outlined below.

    One or more features failed to install Details: Error: 1601. The Windows installer could not be accessed. contact your support personnel to verify that the Windows Installer service is properly registered.

    I then tried Factory Restore: However, Microsoft.NET Framework. Unhandled exception has occurred in your application. If you click continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately. class not registered (Exception from HRESULT.

    I carried on and this came up: I only got Failed to Initialize Volume Shadow Copy service. Maybe some files cannot be backed up. Please close the smaller software and Windows system snapshot and then try again.

    I don't know what else to try. :(
