Well the question is simple, but before that I made a little search on the net and I tried the one on the link
It didn't help me since "run as" doesn't appear when I right click to the program.
Thanks for helps.
Edit: The program that I use is a not a popular program, I tried "run as" and it didn't work, I open session from another user account and tried, it didn't work too. I duplicated the files of the program and that didn't work either.
