Well, you're under very bad impression. You hadn't resolve this in 1.5, nor 1.6 nor latest 1.7 version.
As UniIFF said in other topic: Adobe is unable to code programs that accept any user configuration that Windows supports... Very sad, and very true...
In my case - as you can see in attachment screenshot - "My Documents" aka "Personal" is located directly on "E:" drive (because I like this way...).
I've got the same problem, have just downloaded and installed Digitial Editions and this error has popped up, even though I can easily find the folder manually, so I know it's there.
I'm using Vista Home Premium, and it's a standalone computer, on a small home network, although no one but myself needs it.
It's a pity to see that there aren't really any soultions that I've read that fix the problem.
Also disappointing that there isn't any other software I can use to read this e-book I've just downloaded.
Let me join the club. I also am running Vista Home Premium and am getting the same error. I have gone to every my documents folder and every documents folder and created a digital editions folder. It still does not work. I've been having this problem since 4/2009.
I opened a new case a few days ago and still have not heard from Adobe. I can't beleive that they have not corrected the problem since 2007 when this thread started.
I downloaded this software a couple of days ago and am also having this issue. I've tried everything listed above to correct it, and I still continue to get the error. I checked the knowledgebase, and made sure I had write access to the folders. Nothing works. I get this message when I try to open Digital Editions, and also when trying to download books.
I am running Vista on a HP laptop, sole user, no network.
Recently I had the same problem running Vista SP1. Documents folder was redirected to the root of another disk. Digital Editions cannot make or recognize a digital editions folder in the root . So I made a new Documents folder in the root and moved all the content to that folder. "My Documents"m is now not directing to the root of a disk anymore. And DE works!
Installed DE on two machines and have the same problem on both. Both running Vista (one Home SP2, one Ultimate SP1). Documents folder not in root, not moved at all on one machine. One machine has Reader 8, other does not have any flavour of Reader at all (because I was hacked off with this sort of thing I use something that WORKS). Installed and reinstalled from web and stand-alone versions (twice). This situation is appalling. I now have a £30 file that I cannot read and I very annoyed.
Me too, same problem! Vista home premium SP2, Sony PRS505 reader, ebook library 3.0.0, digital editions 1.7.1. Every time I open it, it says it can't find the folder, yet it is there in the C: root directory the whole time, and indeed if I delete it, running digital editions promptly recreates it (empty), but still says it cacn't find it. Worked through all the suggestions here, no dice. Checked the permissions, firewall pass through, compatibility etc. No good. Tried putting a copy of the folder everywher, in My documents, in users, in users/documents, you name it. Given it full administrator permissions, nothing at all. Can't submit a web support case as suggested 'cos it wants my serial number and the instructions to get it from the splash screen on "about..." don't work. The Adobe support tech note says "Ensure that you have write permissions for the location to which you redirect the My Documents folder." but doesn't tell you how to do this!
This is ridiculous. Without a fix to this stupid problem you can't read any books you buy for the machine!
ADOBE, PLEASE HELP YOUR FRUSTRATED USERS!!!!
