Issue with executable create with deploytool

I created a GUI using matlab. I created an executable with the deploytool and it works wonderfully on my machine. But I want to launch the program on other computers. After installing the MCR (version is OK) on the client machine, the executable runs well until it crashes for no obvious reason.

I looked in the .m code where the executable crashed, for now i'm guessing that

    uiwait(figure(1));

makes the .exe crash.

Has anyone ever encountered such a problem with uiwait ? Once again the problem doesn't occur on a machine where matlab is installed (tested on win32 and win64 platforms with executables compiled in 32 and 64 bits).

Any kind of answer is welcomed, thanks.
