    I sell sophisticated Excel templates to professionals. Want to know if there is a way to "lock" an excel template to a computer. That is, if I sell to one professional, can I keep him from selling it many others or sharing with it all his friends? Certainly, want to sell these same templates to his friends and others. Thank you.

    You could add some code to the vba project and place a value in a hidden sheet (using vba to hide will need the vba code to unhide it) and a copy of this code in a normal hidden sheet, when you sell it and also store this code in the vba project.
    Lock and protect the VBAproject code so it's not visible and if he passes it on it won't work.
    When this person passes it on to another one, maybe he will change that code so that his name is shwon but the it won't work anymore.
    I use a generated serialnumber and code, people like to change this but since it's also hardcoded with every version it blocks or you se a time limit and if they like it, let them contact you for a registration code.

    BTW, welcome to the forum
