Hello,
if i start ZBrush 4 from HDD D: it works fine, without admin rights.
if i start ZBrush 4 from SSD C: it only start as administrator.
Without admin rights, i get a error and zbrush dont start
Is there any way to start ZBrush 4 from SSD C: without admin rights.
ZBrush should be installed and activated by an administrator, after which it should be able to be used by anyone logged into the computer.
When you launch ZBrush to activate it (on Win 7 or Vista) you must enable the option to run as administrator. After activation you can normally disable that. See here: https://support.pixologic.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=52
Many thanks, it works. 
I had only copied the ZBrush 4 folders.
