Windows 7: Microsoft Fixes 62% Upgrade Hang Issue!

Microsoft Fixes 62% Upgrade Hang Issue!

According to Microsoft's Redmond Magazine:
Microsoft issued a "Fix it"-style patch on Tuesday for a Windows 7 upgrade problem that results in a system hang.
The problem, for Vista users upgrading to Windows 7, is that the installer program never completes the upgrade. Instead, some users get a system hang after 62 percent of the upgrade has been completed.
Microsoft is pointing to a Windows Vista plug-in, "IphlpsvcMigPlugin.ddd," as the culprit, according to the Fix it blog. The company had published a workaround with complex steps to follow. Now, users with the problem can use Microsoft's Fix it solution to carry out those same steps and complete their Windows 7 upgrades. Fix its are an attempt by Microsoft to simplify patching tasks spelled out in support bulletins.
The Fix it solution can be applied after the 62 percent upgrade failure happens. At that point, the PC will roll back to Windows Vista. Users can then visit this support page, scroll down and click the "Fix this problem" link. The link will run a wizard with steps to complete to apply the patch. After the patch is applied, users can try the Windows 7 upgrade process again.
Microsoft cautions that this Fix it solution should not be used for Windows 7 upgrades that halt at some other percentage than "62 percent."
Windows 7 was released to the general public last month, but some individuals have reported various problems upgrading from Vista, including an endless reboot problem still under investigation by Microsoft. The main forum for getting help on Windows 7 upgrade issues can be found here, but Microsoft also offers other help resources.
I hope this helps some of our members!

Nice, Thanks. Maybe they needed more of us beta testers to in-place Upgrade Vista? So many of us are clean installers they missed this bug.

Windows 7 Pro x64

Hi, I recently purchased a sealed OEM copy of Win7 Pro x64 from my local computer fair. I was using XP Pro x32. I ran the Windows 7 compatibility checker programme, which returned no potential problems at all. I am doing a clean install. The installation process goes very smoothly until I get to "Completing installation..." with the progress bar stuck on about 60% (there's no percentage figure, just a bar along the bottom of the screen). The HDD light is constantly on, even after I left the PC on all night!

I have read quite a few 'solutions' on various sites, but none of which has resolved the install problem for me
The install DVD is clean, no scratches etc...There has been mention of changing BIOS settings to AHCI, but I don't see this option available. Does anyone have any suggestions I can try, as I am at wits-end with this!!
