Guys Thank You Very Much.
It's awesome that you share your experties on this website, it wouldn't be so helpful and useful without you, thanks for your dedication 😉
I've just created a satandalone app according to Roberts comment, and it works perfectly on Win 64 and 32.
It couldn't be any better.
Many Regards,
%% Previously Posted Problem Hello Everyone.
I have a TTi 12104 Waveform generator comes with drivers and dll file + a console C app that allows sendin simple commands to the device and make sure it's connected and responds.
Device has a single driver for both 64bit and 32bit version of windows(tested on win 7 64bit and XP 32bit), device is perfectly installed on win 7 64bit (with the same driver used for win xp 32 bit) and console app, which uses the the same 32 bi dll file, also works flawless on 7 64 bit.
So the DLL file works on both 32 and 64 bit of windows, this is I'm sure about as I tested myself.
Although when tried to load the same dll into MATLAB 64bit there was this error:
   ...\AWGUSB.DLL is not a valid win32 application.
How come it works in C (on 64bit win 7) but not MATLAB 64bit on the same machine and same windows?! I previously used the same device in matlab 32 bit but I can not use it in 7 64 in MATLAB, outside matlab it's fine with 64bit windows.
I attached the header file maybe that gives a clue. Thanks for your help.

You can deploy a 32 bit version which will run on a 32 bit or a 64 bit computer.
You can't compile a 64 bit from a 32 bit.
Your DLL needs to be compatible with your version of Matlab.
Its perfectly fine to run a 32 bit Matlab on 64 bit windows. In such a scenario your deployed app will run on both 32 and 64 bit machines. It will be 32 bit
