I am a new user of version 6.10. My host computer runs Windows 10 and my client computer is running Windows 7. I want to use the portable viewer on a USB stick. I installed the host. I downloaded the portable viewer to my USB stick. I looked in the Documentation about installing and found easy to follow instructions for installing the host and the viewer on a computer. But I did not find anything about installing on a portable drive. I shall appreciate any help.
