Troubleshooting Installation Issues - Windows 7

Troubleshooting Installation Issues

You might encounter a number of problems before or after installing/upgrading Windows 7. Some of the common problems along with the respective solutions have been discussed below:
Problem 1: Windows Vista upgrade to Windows 7 hangs at 62%
Solution: Follow the below mentioned steps to solve this issue:

1. Reboot, and your PC should roll back to Windows Vista. You can then open the setup log file \$WINDOWS.~BT\Sources\Panther\setupact.log to view what happened. 

1. The Iphlpsvc service might have stopped responding. So adding an environment variable to ignore will fix the problem.

1. Browse the setup log for other clues. And you might also try to boot and install from the Windows 7 disc, if possible, as that reduces the chance of any conflict with your existing Vista (or XP) setup.

If the above steps do not help, use more advanced steps:

1. Restart the computer. Then, your computer will roll back to Windows Vista.
2. Click Start, right-click Computer, and then click Properties.
3. On the Advanced tab, click Environment Variables.
4. Under System variables, click New.
5. Type MIG_UPGRADE_IGNORE_PLUGINS in the Variable name field.
6. Type IphlpsvcMigPlugin.dll in the Variable value field.
7. Click OK three times to close the dialog boxes.
8. Start the upgrade installation again.

Problem 2: Windows 7 setup fails when copying files
Solution: Perform these steps in order to resolve this issue:

1. Disable any security software before attempting to upgrade or do a clean install.
2. Make sure your computer is updated (devices and applications)
3. Disconnect any external devices before installing
4. Check your hard disk for any errors:
   1. Click Start and Type: CMD, from the results, right click CMD
   2. Click 'Run as Administrator'
   3. At the Command Prompt, type: chkdsk /r /f
   4. When you restart your system, your computer will be scanned for errors and attempts will be made to correct them.

1. Click Start, type msconfig in the Start Search box, and then press ENTER.

User Account Control permission: If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.

1. On the General tab, click Selective Startup.
2. Under Selective Startup, click to clear the Load Startup Items check box.
3. Click the Services tab, click to select the Hide All Microsoft Services check box, and then click Disable All.
4. Click OK.
5. When you are prompted, click Restart.
6. Attempt the upgrade again

Also, run the Windows 7 Upgrade Advisor, it will scan your system and provide a report telling you if your PC can run Windows 7 and if there are any known compatibility issues with your programs or hardware.
Problem 3: Installer gives error code: 0×80070570
Solution: This error occurs because of missing or corrupt files.
This problem during Windows 7 installation has been attributed to a bad DVD created from the .ISO file used for the installation of Windows 7. A corrupt .ISO image or an incomplete download too could be the root cause of the issue.
To address this Windows 7 installation problem, you could try and download the .ISO file from a valid source and burn the DVD again using software such as ImgBurn, gBurner or MagicISO at low speeds of about 4x.
Problem 4: DVD drive not found when installing/upgrading to Windows 7
Solution:The standard solution here is to run REGEDIT, browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\, then delete both UpperFilters and LowerFilters in the right-hand pane (UpperFilters.bak and LowerFilters.bak entries can be ignored).
Resetting the drive letter has worked for some. Click Start, type Disk Management and choose the "Create and format hard disk partitions" link. If your optical drive is visible here then right-click it, select Change Drive Letter and Paths, click Change and choose a new letter. If the drive is now visible in Explorer, then repeat the process to change the drive letter back; if it's still not visible, reboot and it should appear.
Problem 5: Activation Error 0xC004F061
Solution: If you receive error "0xC004F061" when trying to activate Windows 7, it means you're using a product key for an upgrade version of Windows 7 and a previous version of Windows wasn't on your computer when Windows 7 was installed. To install an upgrade version of Windows 7, Windows Vista or Windows XP must be installed on your computer. If you formatted the drive before starting the installation process, you won't be able to use the upgrade product key to activate Windows 7. To activate Windows 7, you'll need to install your previous version of Windows, and then reinstall Windows 7.
Problem 6: When upgrading your current operating system to Windows 7 on a computer that is running Windows Live OneCare, you may encounter following message:
“These programs might not work properly after the upgrade. We recommend uninstalling these programs before upgrading. Cancel the upgrade, open Control Panel and search for uninstall a program.”
Solution: This problem occurs because Windows Live OneCare is not compatible with Windows 7.To resolve the issue uninstall Windows Live OneCare from Add/Remove programs. If you cannot uninstall OneCare, you must download and run the OneCare cleanup utility. To do this, follow these steps:

1. Click the following link to download the OneCare Cleanup utility to your computer. Then click Save to save the download to your desktop. 
2. When the download completes right-click the OneCareCleanUp.exe file on your desktop, and then click Run as administrator.
3. Click Run on the Internet Explorer Security dialog box. If you are prompted for an administrator password or for confirmation, type your password, or click Continue, and then, click OK
4. When you receive the message “This program will clean Windows Live OneCare from your computer...” click Continue.
5. Click Accept on the End-User Licensing Agreement, and then click Continue.
6. Click Clean to begin cleaning Windows Live OneCare from your computer.
7. When the cleaning process has completed you will be prompted to restart your computer. Close all running applications, and then click Restart Now.

Problem 7: When you try to upgrade from Windows Vista to Windows 7, the upgrade fails and your computer rolls back to Windows Vista.

1. Click Start and then click Computer.
2. Right-click the system drive, and then click Properties.
