Windows 7 Upgrade Install from Vista is Stuck at 62% Percent

The Vista to Windows 7 Upgrade Hangs & Stops at 62% Percent

I have had a couple people mention to me lately that they have purchased the Windows 7 upgrade from Vista and have run into some problems. Many users are reporting a case where the system will hang at 62% during the Windows 7 upgrade.

This can actually be caused by several factors. To determine what might be affecting your installation you should check in the “Setup Log”. To do this you need to reboot your PC > roll back to Windows Vista > and then check the following file:

\$WINDOWS.~BT\Sources\Panther\setupact.log

(You can open and view this file in Notepad)

This may give you a better idea of what happened that caused the system to hang at 62% during the Windows 7 upgrade / installation.

Microsoft has reported this issue can commonly be caused by a service called “lphlpsvc”. What this means to you as an end users is you should go to the Microsoft Support site and get the hotfix for this problem which can be located here:

http://support.microsoft.com/default.aspx/kb/975253

If the hotfix doesn’t correct the issue you may want to double check the Setup log for any clues as to other issues that may be causing the problem. This information can be helpful if you are familiar with PCs or are troubleshooting with tech support.

If all else fails I recommend attempting to do a clean install of Windows 7 as this is the least problematic way to upgrade to Windows 7. Just make sure you have all your data backed up beforehand as a clean install will format your hard drive.
