Shibb IDP upgrade from V3 to V4 at Diff Path

[Rod Widdowson]

This sounds like a bug.  If you put a case into JIRA I'll get to it.  In the report make sure that you include the value of 

	HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Shibboleth\IdP\InstallDir

I have to say that I'm super suspicious of the paths since the windows installer has 32 bit components so having it in "Program
Files" is a bit weird.

Meanwhile you might get some mileage by setting INSTALLDIR on the command line 

	msiexec /lvm log.log Installer.msi INSTALLDIR= D:\Program Files\Shibboleth\

But to be honest if you are managing your own container you are probably best to just ignore all the msi nonsense and do a manual
install from an unpacked  distribution[1]
