When installing the software, are there any permissions issues that I should be aware of?

Yes.  It is likely that you will need Windows Administrator privileges in order to install the software.  If you don't have these privileges, you should contact a system administrator at your site.

Once Kadoe Client is installed on a machine, you should determine whether any non-Administrator users will be using it.  If they will, then you need to ensure that folder permissions are correctly set.
