How to fix a Windows 7 upgrade from Vista that is stuck at 62%
by Lee Mathews Nov 2nd 2009 at 2:00PM
Once the installer hits 62% complete, it locks up. You can sit and wait as long as you want, but it's not going anywhere.
The problem occurs when the Windows IPv6 helper service (which allows automatic IPv6 connectivity over a much more common IPv4 network) stops responding . Microsoft has posted a fix to this particular problem, and it's not terribly complicated.
- Restart the computer - your system will automatically roll back to Windows Vista.
- Click Start, right-click Computer, and then click Properties.
- System Properties will open. Click the Advanced tab, and then click Environment Variables.
- Click the New button.
- Enter MIG_UPGRADE_IGNORE_PLUGINS into the Variable name field.
- Copy the following bold text: iphlpsvcmigplugin.dll and paste it into the Variable value field (or type it manually)
- Click OK three times to close the dialog boxes.
- Re-launch your Windows 7 Upgrade installer!
You may also want to run the System Readiness Tool for Vista and Windows 7 before trying the upgrade again. It can detect and correct certain issues that may cause trouble during the process.

So, just how good at time waster games are you? Think you've got the stuff? Well, The World's Hardest Game 2.0 doesn't think you do.
Yes, amazingly, it's possible to have a sequel to a game called "The World's Hardest Game". It doesn't seem logically possible, since if the first one was actually the world's hardest, how could another one come along and share the moniker? It made me doubt the name in the first place. That is, until I tried the game.
The mechanics of the game are very simple. You are a small red square, ...

The fact this even happens in the first place is pathetic.

Mistakes happen, yes, they have made mistakes before, but they do happen.
At least it doesn't "accidentally" delete all use data..

You've heard of such a thing as a bug, yes? You realize there's literally hundreds of millions of people with windows installations? Something's going to go wrong with that many people doing who knows what to their computers...

That this is even an issue in my view is absolutely unforgivable on Microsoft's part.
After all the testing that Windows 7 is supposed to have received, this now surfaces?
And what about all the media reviews done over its development cycle? How was that missed as an issue?
Mac fans are, rightly, going to have a field day with that one!

Again, it is a very specific problem, and is in no way wide spread.
Overall windows 7 is amazing, way better than the travesty that was vista, and apple "fans" will find anything wrong with a windows system.

It would have been missed because most people don't upgrade their production systems using Beta or RC software (they'd have done a separate or clean install), so that's why, and it wouldn't have been supported by MS anyway.
Mass testing of upgrades would never really have happened until after it was finished.

Also considering there are millions of different hardware combinations that Windows can run on, a few odd hiccups are nothing to scoff at.
Bare in mind that Mac runs on a much more limited choice of hardware, its far easier to test upgrades for them.

It took 3 hours for Windows 7 install on my Vista computer. It sat at 62% for a while at transfering files, photos ... then rebooted and finished installing

I have luckily been able to avoid most if not all of the problems people are having with W7. From what I hear pretty much everyone thats doing the upgrade is having some amount of difficulty, if not with problems like this, at least with significant upgrade times. Anyway, good article.

It took me nearly 7 hours to install Windows 7 on my sisters HP. At least it's aptly named. Never again will I purchase a Windows based computer.
I had to set my default browser to Safari because Internet Explorer was failing to connect to anything, as well as delete a slew of programs that wouldn't successfully transfer over to Windows 7, including iTunes. It was no where near as easy of a process as Snow Leopard was. 7 Hours versus 45 minutes. You tell me what the general audience is going to start choosing once they start seeing these horror stories?

And how come nobody from the fans of Microsoft think this is "too difficult"? Had it happened to be an article on Linux on how to solve an issue they would dismiss it as being "too complicated". This is not how grandma would solve it, isn't it?

I had very few issues going to 7, yeah it took a while, but I followed the golden rules:
1. Remove all the crap from your computer before you begin.
2. Open a nice bottle of wine.
3. Relax.

Clean installation is always better, you'll feel fresh feeling when you use it than upgrading.

So far all iv'e read about is installation problems with windows 7. Iv'e tried
twice to upgrade and can't get past the first of three steps. Now my computer is telling me the cd is not working! If this is supposed to be a free
upgrade as promised when i bought my computer, why won't the &*$%^# thing work?
