"Server Creation Failed" when I run a Prok.Phantom

I'm using the Prok-Phantom library for Phantom Omni haptic device: http://code.google.com/p/prok-phantom/downloads/list

Actually I run it successfully in my 32-bit computer with win xp OS, 32-bit Matlab. But for now I want to run it with my 64-bit computer, win 7 OS.

For this library, the requirement are: Windows 2000/XP/7. Matlab 6.5 or higher (32 bit, no toolboxes required) Installed Open Haptics Toolkit is required (hd.dll) (<http://code.google.com/p/prok-phantom/>) which have been met in my case and I am using the 32-bit Matlab 2012a.

But I get the error:

Error using feval Server Creation Failed:

Error in actxserver (line 87) h=feval(['COM.' convertedProgID], 'server', machinename, interface);

Error in my>my_OpeningFcn (line 71) h = actxserver('Prok.Phantom'); % Activate this component

I have no clue for this problem, anyone can give me any suggestions? Thanks!

Did you eventually find a solution for this problem? I am experiencing a similar error. Thanks!

It is not possible to call a 32 bit DLL from 64 bit MATLAB; this is an operating system restriction (a restriction most operating systems have.)

Did you find a solution to this problem? I am experiencing the exact same problem. Thank you so much!

Irena Arslanova: this is a fundamental incompatibility between 32 bit and 64 bit software. In my decades, I think I have only heard of one operating system that had a way to support calling libraries compiled for a different number of bits.

The best way around this is to get a 64 bit driver for the device.
