Solved! Go to Solution.
I have tried to get a Creo Express Viewer - the website says I should get an email with download instructions after submitting info - but this email never arrived (not in junk email either)
try it once again using different email address.
Try the following link: https://www.ptc.com/en/products/creo/creo-view/extension-express/free-download
Thanks - this worked excellently!
