Win7 upgrade from Vista stuck at 40%

Bottom line, while I did not go thru the logs (which are found here oddly C:\$WINDOWS.~BT\Sources\Panther\), I saw I had a RAID system with INTEL. I powered the Vista box down, which upon reboot, rolled back to Vista, then updated the RAID driver thru Device Manager, then re-ran the upgrade and it completed.

Initial glimmer of what was going on: http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_install/windows-7-upgrade-reaches-60-and-hangs-at/e40168ad-6468-49bc-8262-ed3218d9e56e

You may have the Intel Matrix Storage Manager or the Intel Turbo Memory driver installed on your system (or both may be installed). If they are installed on your computer it is recommended that you find the latest version of each of these applications and update them prior to performing the upgrade.

Once you have cancelled the install and the system has done a roll back to Vista you can check to see if they are installed on your system by checking Programs and Features in your Control Panel (via the Classic View). If one of these applications is displayed in the list of programs you should update it to the latest version prior to running the upgrade again.

I took

File name: f6flpy3289.zip	Version: 8.9.0.1023	Download
Date: 07/17/2009	Status: Previously released
Size: 0.2 MB	Language: English
Operating Systems: Windows Server 2003 , Windows 7 , Windows Vista , Windows XP

I went into device manager and found the storage controller, looked at the driver,saw it was INTEL, and expanded the file to a directory and in Device Manager, updated the driver.

I did not have to contend with this issue but capturing it here as a footnote: http://social.technet.microsoft.com/Forums/en/w7itproinstall/thread/e67ab25c-c533-42fe-b5b0-541ad8f2c168

Hello,
Just posting at the bottom of the thread.
This is for the 62% hang, this is not for the 63% hang, see the next post for 63% status

Symptom

During the upgrade from Windows Vista to Windows 7, the upgrade hangs at 62% indefinitely.

Note this issue is only for hangs at the 62%,

Cause

The iphlpsvc service may be hanging during the upgrade. This is one service that has been identified as hanging at this point during setup.

Resolution

Reboot the machine, this will cause a rollback to Windows Vista.

Go to the start menu

Right-click on Computer

Choose Properties

Choose advanced system settings

Choose the Environment Variables button

Under System Variables choose New

Then enter

Variable Name: MIG_UPGRADE_IGNORE_PLUGINS

variable value: IphlpsvcMigPlugin.dll

Then Restart Setup.

This workaround only applies to the iphlpsvc service hangs

More information

This hang can be seen in the setupact.log

With the following line repeated about every 15 minutes.

<TimeStamp> Warning [0x080b50] MIG AsyncCallback_ApplyStatus: Progress appears to be stuck. Current progress: 62

If this entry is not occurring in the log file or you are hanging at a percentage other than 62% this workaround should not be attempted.
