Hi A.T. Romano,
Sorry for the inconvinience.
Actually with Elements12 Serial number validation happens online.Due to some firewall or network issues, sometimes serial number(SN) validation fails for win Elements12.
The simple solution to this is to restart your machine and try to install with SN.
As you could see in your case same SN worked on your Win8 machine without any issues.
Also the other issue mentioned in th forum http://forums.adobe.com/message/5711110#5711110 was Mac only and it was due to server issues.
Hope it resolves your concern..
Thanks for the reply.
In my case, I had the network firewalls and anti-virus disabled when I did the installs of Photoshop Elements 12 and Premiere Elements 12 on Windows 7 64 bit as well as Windows 8 64 bit.
I was fortunate in that a 5th try of the serial number entry for the Photoshop Elements 12 install on Windows 7 64 bit was successful, so I did not have to do the computer restart and retry of the install with the purchased serial number. But, good to keep in mind, just in case.
It is ironic...last time around I got caught up in the Shared Technologies issues with Photoshop Elements 11 and Premiere Elements 11 on Windows 8 64 bit, not Windows 7 64 bit. But, in that case, I did find my way eventually to a successful install on Windows 8 64 bit. This time around it was Windows 7 64 bit where the glitch occurred, but, for me, only for Photoshop Elements 12.
But, could you clarify...are you generalizing that Photoshop Elements 12 Mac Invalid Serial Number is due to server issues and Invalid Serial Number encountered by Photoshop Elements 12 Windows is "online - due to some firewall or network issues"?
Just getting prepared for if and when more questions on Invalid Serial Number might pop up in this forum.
I would not say that this is a general scenario but yes,it would be the first check/workaround for Win atleast.
For Mac, hopefully there should not be any more issues since the fix has already been taken at our end.
Many thanks for your replies on this matter.
Your information will be very helpful moving forward.
I purchased the box version of premiere elements 12 for Windows and my serial number was invalid I have tried it over 30x but it still keeps saying invalid, this is extremely frustrating especially when I played for a product that won't let me get in, can anyone help me???
Have you tried the install with the antivirus and firewalls turned off? If not, please try that, then....
