Not sure if you have the correct serial number for the copy of Sketchup that you have downloaded? Here's how to tell if you have the correct serial number...
It is possible to determine the whether a licence is commercial or educational and also the version and platform type, from the serial number.
The first letter of a serial number depicts what version the licence is:
U = 2019
T = 2018
S = 2017
R = 2016
Q = 2015
P = 2014
N = 2013
M = version 8
L = version 7
K = version 6
J = version 5
When the second letter is:
"H" (as in RH) - the serial number is educational
"A" (as in RA) - the serial number is commercial
"C" (as in RC) - the serial number is an NFR (Not For Resale)
"F" (as in RF) – the serial number is an educator (teacher) licence
For pre-2015 licences:
Upper case serials are Windows, and also the last letter of the SN is ‘W’
Lower case serials are Mac, and the last letter of the SN is ‘m’
All new licences will end in an ‘R’
Note that each version has a distinct authorisation code so just changing the first letter of your licence will not make it work in another version. Upgrades and downgrades are free of charge for valid licences so please e-mail us at firstname.lastname@example.org if you need to change versions.
