I have DOSBox 0.74 and it runs just fine on my 64 bit Windows 7. DOSBox itself is a 32bit application so it should be able to run. Try running it as an administrator and see if it will start, it's possible that there is a permissions issue that is blocking the program from running.
i am using windows 7, 64 bit
dosbox 0.74 is not running in it.
can any body help me to search for suitable version of Dosbox for it?
Supernova is correct. Also if all else fails open disk management console and create a 32 bit virtual drive then install dosbox on that.
It works for me when i get the craving for the old wing commander series, and privateer. Works like a charm
