I picked this one: http://www.microsoft.com/download/en/details.aspx?id=3387
you need 64 bits version 
http://www.microsoft.com/download/en/details.aspx?id=21254
Uninstalled both 32 and 64 bit packages, reinstalled the 64 bit package, and: no effect!
OK, i make a special "old package" for you in 2 mn
here we go :
http://perso.numericable.fr/popolon/hoot/hoot20101231.7z
just run it
EDIT : if this don't work, i think you also need the MSXML package from microsoft in order to use .XML dependencies.
Ok, this version runs! I've no idea what the difference would be compared to the other options, but alas. Tnx!
Hoot2011 version need VC2005++
Hoot2010 doesn't need it 

Sure it is 
by the way, if you need some rips of specific MSX games, let me know
Bye
Thanks for popolon, I've finally the sound with the PC88 files !!! 
So, I confirm wolf_ conclusion : an old version can be better ! 
I've encountered also this kind of problem with a WordPress plugin : new versions are buggy, some old versions are perfectly working !!!
Btw, PC88 music is excellent, MSX should have the YM2203 chip !!! 
All is a question of configuration and to find the correct runtime libraries of windows, i think.
I'm using the latest Hoot version (20111231) and it's working like a charm, the sound driver emulation is even better than with the older ones 
Oh, and if you like OPN(YM2203) soundtracks, try some OPNA (YM2608 from PC88VA/PC98), it's even better with much voices.
