Symptoms

You are running an x64-based version of Windows Vista or of Windows Server 2008 on a computer that has multiple Intel x64 processors or has an Intel x64 multi-core processor. When you try to install Windows Vista Service Pack 2 or Windows Server 2008 Service Pack 2 on the computer, you receive the following Stop error message:
Stop 0x0000003E (parameter1, parameter2, parameter3, parameter4)
MultiProcessor_Configuration_Not_Supported
Note When this problem occurs, parameter1 and parameter2 in this Stop error message can make the following equation valid:
((parameter1 ^ parameter2) & (0x00100000))!= 0

Cause

This issue occurs because some processors on the computer report support for some unsupported feature sets. Therefore, when the system uses these feature sets, a Stop error occurs. This situation can occur if incorrect processor packages are used or if the BIOS incorrectly enables a processor erratum.
