We need a wee bit more info from ya...
Like, first, what planet are you currently posting from... (With a preposition at the end of, of course!) ?
Are you running anything from a motherboard to a video card made by MicroStarInternational ???
(They make really ACE video cards, at the least !)
((And, of course, .msi could also refer to Microshaftidiot... Not you, THEM !!!))
Tell us all the details and some nut here will be able to help you, OK ?
Also... In the meantime, do a GOOGLE search for
rnenu.msi
You will find that you are not alone !
But, you must try to tell us just exactly what it is you are trying to do and what is being 'prevented' from running...
If it is possibly a ripped-off game, than you are deep-doo-doo out of luck here !!!
