You can try Adobe Chat, but I do not believe it will give you any support on this matter because you are not dealing with the current version which for now is version 12/12.1. Coupled with that is the situation where this is not a serial number/program activation matter. It is a feature activation issue. Different story.
There have been several what seemed like insurmountable problems in this regard, especially with MPEG2 Activation and Premiere Elements 8.0 and versions earlier than 8.0/8.0.1. But some have solved the problem with
- uninstall the program via the usual Control Panel/Programs way
- do a free ccleaner run through (regular cleaner and registry cleaner parts) https://www.piriform.com/ccleaner/download
- reinstall the program with antivirus and firewall(s) disabled.
Please let us know if any of that works for you also.
Thank you for taking the time to reply, i shall give this link a try.
Thank you for taking the time to reply, i will try doing as you suggest. I have used the program before without any issues and have now reinstalled it onto a different machine.
Thanks for the follow up.
Did the issue present itself when you tried to use Premiere Elements 7 on a computer which had never seen it before?
Thanks ATR, it was working fine on a different PC (has since been rebuilt), but started doing this on a different/newer PC that i had. I have also tried installing it onto a different machine (we have 8 licences here) and i get the same problem. I appreciate that an older version may not have support, or may lack some functionality, but it must still be allowed to work surely. At the end of the day we did purchase the software. Seems very strange.
Thanks for the reply.
Reflecting on this....the overall program does require activation at installation. But, there is also required activation for specific processes within the program - typically on a one time basis. Typically you see the latter when you go to use one of this processes that need first time activation.
What you seem to be facing is the first time activation needed for the use of MPEG2 in the burn to DVD-VIDEO whose video files will be MPEG2.vob. Recently that Adobe statement surfaced about it not providing this MPEG2 activation for Premiere Elements 8 and earlier versions of the program. I am guessing that this one time activation is related to a program on its computer at component activation rather than a blanket MPEG2 activation for that program being used on another computer.
In view of the Adobe statement, it appeared as an Adobe write off of features for the Premiere Elements 8 or earlier users. Yet, some facing this situation, have come back to the forum to report that the uninstall, ccleaner, reinstall with antivirus and firewall(s) overcame the problem. I have no other details of how these users accomplished this success.
But, if you are saying that you also cannot use features of the program unrelated to MPEG2 activation (cannot even open version 7), then there is more going on that needs a look at. If MPEG2 activation is the only issue
a. have you tried to uninstall reinstall latest version QuickTime
b. have you tried the workaround of export to Share/Computer/AVI or Share/Computer/Windows Media and then burn that file to DVD-VIDEO on DVD disc with a DVD-VIDEO authoring program - one example Windows DVD Maker.
Did you end up purchasing Premiere Elements 12? Did you look at the version 12 tryout from Adobe first?
