Troubles using a STG 4004 with Matlab R2009a: cannot run .dll files in DOS mode

hello,

i want to use matlab2009a (32bit) on a window7 (64bit) pc to command a STG 4004 stimulator.
it is very surprising because the setup has been used successfully for years and doesn't work now.

matlab cannot open the mcsusb.dll using the loadlibrary function saying errors signifying it cannot run .dll on DOS mode.

the stimulator STG 4004 is not recognized by matlab which then cannot initiate any stimulations…

does anyone know what could be wrong and fixed?

many thanks in advance!

best

martin vogel

Can you please post the complete command and error message?
