[vbox-dev] Error creating Session instance! rc = 0x80040154

[Nikolay Igotti]

    Have you tried running VBox own frontend? Does it work for you?
As you probably noticed, 0x80040154 is E_CLASSNOTREG, and means class is 
not registered.
This problem may appear, if you installed 64-bit VirtualBox, and try to 
use it from 32-bit COM client, or vice versa, as 32 and 64 bit COM 
classes use different registry subtrees.
This is internal Microsoft COM limitation our team couldn't help with, 
so just use client of matching bitness (32/64 bit client/server mixing 
will work with XPCOM on other platforms,
as we have control over source code and fixed it for such usage scenario).

    Nikolay.
