Yesterday, I was upgrading from Windows Vista to Windows 7 on my Sony Vaio Laptop. The installation of Windows 7 suddenly stopped. I first thought that, it will start. But, after sometime i was sure that Windows 7 Installation Hanged. Windows 7 Installation stopped and Hanged at 62%.
I then restarted the Laptop. But, again Windows 7 Installation failed and hanged at 62%. It was strange.
I then tried to find the solution on the Internet via Google God. I was happy to find a solution. I would like to share the solution with my readers on this blog.
If you look into setupact.log, you should be seeing the following error message which is repeated every 15 minutes is logged:
It turns out that the cause of the problem is because of iphlpsvc service. iphlpsvc service hangs during the upgrade.
