Protect excel template being overwritten

Hi,

I am having issue with users overwriting the excel template that I have created, ie opening the template through File-Open-changing the layout-Saving it.

Is there a way that when a user opens the template from File-Open method, it always opens a new instance of that template, so if the user makes any changes and then try to save that they are forced to make a new copy. Thus the template I created can't be overwritten and remains intact.

It would be very helpful if someone can suggest me the way.

Many thanks
Niraj

Save it as a proper template - *.xlt

Try protecting the cells you do not want changed, Lock the cells you do not want changed and protect the workbook with a password this way only the cells you have unlocked can be changed by users.
