I am sorry for the inconvenience caused to you.
Please follow the below suggestions and check for the issue.
If you are using a corporate or company network, please follow the below and add the URLs to the whitelist of the network firewall.
If you have connected to your home network, please follow the steps provided in the below link
Let me know if this helps.
Please review what I wrote again. I said:
Yes, I'm one of those behind a corporate firewall. I've checked with our IT on our Zscaler config. I've also connected the desktop to our guest wifi, which is more open. I also disconnected from all networks and tethered it to my iPhone. A completely open network. No difference.
I've uninstalled McAfee. I've turned off the Windows Firewall.
My corporate firewall isn't the issue.
Please put me in touch with someone who can review Adobe activation log files.
Have you created an Adobe account? You need to be connected with your Adobe Account via the internet to activate the software.
To clarify, when I said:
I try to install LR6 (perpetual license) and get the Sign-In page. It spins and never connects/prompts.
I mean that the window that has the "Sign In" button never actually prompts with a login prompt. It times out. It never actually asks me for my username and password.
Yes, I have an account.
Could you try the following.
Shut down your computer and reboot.
Go to the Adobe website and login to your account.
If this is successful open Lightroom and then proceed to enter the serial number to activate the product.
See if the following web site can provide any assistance.
Yes, I've done all that. Multiple times. With online chat support and before online chat support. The URL you've provided assumes that I can login to the "Sign In Required" screen, or that I have Lightroom already running.
Lightroom will not come up. It comes up with the Sign In Required screen. When I click on the button, it never prompts for my login. It times out and gives me the option of Retry or cancel (and quit.)
Yes, the chat agent had me try those already. Hosts file is clear. I can access the websites under (3). Clock is good. I can access https://adobe.com Firewall is off.
One thing I need to try again when I have a chance is my iPhone test. I realized that when tethered to my iPhone the iPhone may have been connected to local wifi in addition to 4G. So I need to turn off wifi on the iPhone, tether, and try activating solely over 4G. That would eliminate all corporate networking possibilities.
