mental ray help
 

i know this is gonna sound really cliche or a common posted problem but ive done numerous searches and still get the same problem:

evertime i try rendering with mental ray I get
// Error: (mental ray) : cannot load D:/<some location>/mayahair.dll, The specified module could not be found. //
then i get the same note for mi_openexr.dll,paint.dll,subsurface.dll,contour.dl l,mayabase.dll,physics.dll,base.dll.
but the thing is that all of those files are present in that location. and I tried turning on mayatomr.mll in the plugins but it still doesnt work. is this the same issue with you guys at all because this seems to happen to me everytime i install maya and on different computers too.
