Trying to install an older version of ADE will not work, as I'm told I have to use the newest edition.
Where were you told you needed the newest edition?
Have you tried using an older one?
Have you got an eReader device plugged in while you try this?
I found that with the Sony PRS-350 plugged in, it stopped quite a few features of ADE2.0 working correctly, especially with library books.
That was even without trying to copy anything to the Sony; just trying to read the book on the PC.
If I unplugged the Sony and I could read the books fine on the PC.
Sounds crazy I know, but true. Others have seen similar with other eReaders.
In my case, installing the older v1.7.2 solved all the issues.
When I try and download a library eBook, I'm told to upgrade to the latest version if I'm not running it. I've tried using v1.7.2 (as that's what I used before the upgrade), but it's when I'm attempting to download the eBook that I get that error message.
It doesn't matter if I have an eReader (Kobo Glo) plugged in or not, the same situation applies both ways. ADE will recognize my Kobo, but will not transfer anything to it. In any case, I can't even get books to download TO ADE in the first place, even without an eReader.
Anyone have any info? It's near impossible to get a hold of Adobe support. I was on hold for over 2 hours the other day and still couldn't get through!
I can't think of anything else I am afraid, so I'm going to try a couple of slightly silly/hopeful suggestions ....
Is the error message about needing to upgrade really an error message, or just a warning that an upgrade is available?
Sometimes you can carry on by ignoring such messages; either dismissing them or just pushing them to one side.
What machine/OS are you on?
Is it definitely v1.7.2 you are using as the earlier version, not just some other earlier version?
I seem to remember someone else with similar issues that turned out to be because they were using an even earlier version.
That person was on a Mac; I don't know if that was a releavant part of it.
It is an error message, and not something I can bypass, unfortunately.
I'm on a PC, using Windows 7.
It is definitely v1.7.2 that I'm trying to use as the earlier version, I'm getting the link directly from Adobe's site.
Thanks for all your help. I'll keep trying with Adobe technical support...
