Unable to start "...\..\bin\siftGPU.dll", is not a valid win32 application

Hi all!
I'm quite new in CMakeFiles and other so my question might be trivial. If yes, I'm sorry.

I'm working on VS2017, windows 7 (x64)and I'm trying to build SiftGPU.
Since I use VS, I used the sln project, and resolved all linking errors. Now it compiles fine, but when I try to execute simpleSIFT.cpp, it generate 2 errors :
"Unable to start 'E:......\msvc\SiftGPU....\bin\SifTGPU.dll' ", 'E:......\msvc\SiftGPU....\bin\SifTGPU.dll' is not a valid Win32 app.

What should I do?
Do I have to build the project with Cmake in order to make it works? :/

Thanks
