Thank you very much, but this doesn't work for me.
I had the "take ownership" already, and I added your .reg file.
It added a "take ownership" to my .exe file, but when I use this it opens the file instead of giving the ownership.
I used this on Magnify.exe, and it opens the magnifier instead of giving the ownership.
I want to delete magnify.exe and replace it by a clean version. Because this one has a problem and closes itself everytime, as for the clean one it works great.
