Problem installing 6.5 on another pc

Hi there,i attempted to install 6.5 on another pc but faild ,problems with the e licencer(usb)but it is still working ok on the original pc .first of all do i need to install cubase 4 (i skipped 5)first, because 6 and 6.5 are only updates . do i need to install the e licencer software on this other pc first and do i need to install all the .net frameworks all the way from 2 up to 4.5. thanks

Up to 7 all updates are full versions - use the search plenty of posts about that exact matter…
You need to make sure in the end you have the latest eLC-software.
