Proteus VX, Virtual Sampler/Sample Player from E-MU.
Is this after you download the files from this site (Audiofanzine)? Or is this in the process of the download?
I'm having the same problem running install after downloading. Windows Vista OS
K ... figured it out.... re download the software at the link presented here if running a download utility turn it off !. Next b4 running setup turn off your antivirus for duration of setup. Hope this helps...
