If there is pertinent information in your previous replies on the same subject then including links to those replies would be helpful for those of us who use e-mail to read and respond to the forums. We cannot see that you have other threads on the same subject without going to the web version of the forums. I am another Lightroom user like yourself, not someone from Adobe. Your replies to previous messages, which I did go to the forums to look for, indicate the ProDesignTools webpages either are not visible to you or do not make sense to you. There are seven steps, numbered 0 to 6, on the ProDesignTools webpage within the Very Important Instructions section also previously referred to. Aside from perhaps some brief periods of server maintenance, which I have never personally experienced, the ProDesignTools webpages are available and do work, so if you cannot even get those pages to come up, it suggests you have issues with connectivity to things on the internet, perhaps due to an iffy connection, or perhaps due to a virus or malware scanner that isn't playing nice. Why only LR is affected, is unclear. Can you confirm if you can see the ProDesignTools pages, and if so, do you see the Very Important Instructions and steps 0 to 6, which involve setting an Adobe authorization cookie, so if you are following steps 0 to 6 and get an error from the Adobe download page that ProDesignTools eventually redirects to, then you might have cookies disabled. Of course if you can't even see the ProDesignTools pages, then you're getting stopped before anything to do with cookies is occurring. Being more specific and detailed about what you're doing and what errors or unexpected conditions happen would help the rest of us not be confused as to what your situation is and not give confusing answers. However, you are correct that the ProDesignTools trial is the serial-number version, which is different than the Cloud version, or at least that is my experience. A reason to try the serial-number version would be to see if LR installs for you, in case the 42% that the Cloud installer is stopping at is really a preliminary install step rather than a download step and maybe the serial-number version is easier to see error messages from. Some times screenshots of your error situation can be helpful. Another place to get the LR serial-number version, would be the Adobe updates page: http://www.adobe.com/downloads/updateswhich would also be the most up-to-date version, LR 5.4, rather than LR 5.0 that the trial might still be. If the serial number version of LR installs from either of the above locations, then before trying the Cloud version of LR, again, you'd want to uninstall the serial-number version, and log out of or quit the CC Desktop app, then restart it, so it'll rescan what apps are installed or not.
