Re^2: How to escape space in registry path?
in thread How to escape space in registry path?
As far as I remember, Windows started "virtualising" filesystem and registry access with Vista / 2003 Server, depending on flags in the EXE header, WOW64, user privileges, and perhaps some other factors. I.e. things are not were you see or search them, some code by Microsoft rewrites the filesystem and registry paths. It's all documented somewhere at microsoft.com, good luck searching ... :-(
Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)
