Hi Guys
I want to protect a woorkbook that I have used more than 300 hours to develop.
I want to protect it against copying of the program. E.g. by restricting user access to specified user list and by somehow a key or digital signature
Still the users must be able to enter data, make calculations, change in diagrams (e.g. x-y scale) and make print outs
I'm looking at XL Safe Pro from www.datasafexl.com whichs seems to be able doing the job.
This cost however 299$/year and pehaps teher are additional costs(?)..... is there any free programs doing the work?
Has anyone experiences with this Ad-In (XL Safe Pro)? Pros and cons?
Thanks
Best regards
Henrik
