Sorry for overlooking the information in the previous post. My intention was only to get the right answer faster as the problem is common and had occurred before. So please accept my sincere apologies.
Fortunately, we were able to discover the real reason about this error. It usually occurs if you already have a virtual directory with the project name you want. In your case: dmajkic. Let us know if this is not the case.
Also, it is odd that you get the 'Role feature is not enabled' error. The roles are not disabled for the community edition of Sitefinity. Actually, they are set to false in the web.config file, but set to true programmatically in the second step of the wizard. Perhaps a workaround would be to open the web.config with some text editor and change the property to true (when this error occurs). You should change
<roleManager enabled="false" cacheRolesInCookie="true" defaultProvider="Sitefinity">
<roleManager enabled="true" cacheRolesInCookie="true" defaultProvider="Sitefinity">
Refresh the page. Hope this would help.
