A while back I ran into a Premiere Elements 12 Sign In issue where the message was that there was no Internet connect and/or the computer clock was the problem. Neither was the case.
The fix was updating the Adobe Application Manager - How To described in following blog post.
Sandeep Singh who replied to your question with a generalized CS5.5 and later Adobe document in post number 1 was the one who suggested this fix that worked for me.
Since this was a Premiere Elements 12 fix for a Premiere Elements 12 problem, please review and consider the blog post content for solution
for your Premiere Elements 12 issue.
We are looking forward to your results.
I read the articles but none of them gave me a solution
I guess as I work in a big company, which means that almost all internet pages are blocked, including changing computer settings, I'll have to ask for a IT partner to help me with this. I think that the system is restricting me to sign in
Anyway, thank you both for your help and concern !
Thanks for the follow up with the news that the prior troubleshooting suggestions did not lead to a solution to your Premiere Elements issue.
We will be watching for the outcome of your consultation with your IT people regarding permissions.
Just some of the considerations....
1. If you have not already, please retry the above with antivirus and firewall(s) disabled.
The program needs to be run from a User Account with Administrative Privileges.
The company's system security needs to be evaluated disabled and enabled when the problem exists.
If you are in a company environment, your IT associates may be the only ones to help.
