This is a public forum not Magix Support.
We need more information:
What is the full name/version of the program?
What error messages are you getting when attempting to re-install? Screenshots would help.
. . . . Dell PC . . . .
What is the specification of your computer system including Windows version and program version, see this topic for what is required and please quote processor and graphics card make/model in full, and also what monitor/screen resolution(s) you are working with if this is a laptop.
I would suggest you put this information in your profile signature so we do not have to keep asking for it.
