msbuild calling powershell script under windows 7 gets signing error

We have a powershell build script that calls out to other scripts that is giving me trouble under Windows 7 64 bit. It works fine under XP. I've run set-executionpolicy to RemoteSigned (and also tried it with Bypass and Unrestricted). I can pull the command line from the error message and run it myself and it all runs fine.

Build errors look terrible here; but I'm including them anyway for completeness.

Just guessing: You did run Set-ExecutionPolicy in your x64 PowerShell and the build runs the x86 PowerShell?

Maybe try Get-ExcutionPolicy in both shells.

Edit: oops, I see you already enabled scripts. It's possibly something to do with the context under which MSBuild is running. Are you running MSBuild as a local service account of some kind?

Edit2: It's clear the error message is deceptive. There's something else going on and the execution policy error is being thrown but not for the expected reason. Perhaps as a way to isolate, try creating another MSBuild task that runs the same line but with shorter, hardcoded paths instead of the /../../../ bonanza above?
