The problem is that I don't have any clue on how to solve this. I've
googled around and there seems to be similar cases, but no explanation
solution, maybe there are some restrictions when loading a dll?. Just to
have a bit more infomration, which Win32 OS are you using, XP, Vista, 7?

And we can't even put a decent timeout since according to

the alternative is to have a timeout of *2 minutes*. I really don't know
why thi is happening, but I don't think this has an easy fix. BTW this
function was necessary to obtain a bootup time that does not change with
hibernation or clock adjusments, previous bootup timestamp function was
a huge source of problems for Interprocess users.
