Windows 7 Installation Hangs When Upgrading from Vista – Fix


windows 7 upgrade problems 1 Windows 7 Installation Hangs When Upgrading from Vista   Fix

When upgrading from Windows Vista to Windows 7 the upgrade setup may hang at 62% indefinitely, and restarting the setup will only get it stuck at 62% once again.

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.

Note: There can be other services that may cause this hang or this log entry.

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

The fix below is only for hangs at the 62%:

1. Reboot the computer; this will cause a rollback to Windows Vista.
2. Click Start, and right-click Computer.
3. Click Properties, and then click Advanced System Settings
4. Click Environment Variables.
5. Under System Variables, click New, and then press ENTER
6. Type in the following variable information:
Variable value: IphlpsvcMigPlugin.dll
7. Then Restart Setup.

Note This workaround only applies to the iphlpsvc service hangs
