All .boo files are present, but like you guessed, no boo script cache.dll file. The "compiling scripts" did appear, and no message error appeared. After running it once with Admin privileges, the file is created, and the scripts appear fine in all subsequent runs.
Thanks for the help!
And, while I'm writing a post, I figure I'll ask something else. My music collection is in a folder structure like this:
C:\Music\<First Letter of Artist Name>\<Artist Name>\<Year> - <Album>\
For example:
C:\Music\A\A Perfect Circle\2000 - Mer Des Noms\
I know that the Artist and Album are available as parameters to pass to the program, but is there any chance to get the Year and First letter as well?
Great, I'm glad it's working now. Knowing that this was an Vista admin privileges issue I can try and put a workaround in for the next version.
For a path like the one you are using, I don't think Album Art Downloader will be able to save images to the right path automatically. For one thing, it won't have any information about the Year of the album! I suppose with titleformatting style scripting getting the first letter of the artist would be possible, but I have no intention to implement anything like that. In your case, you would be best off getting foo_run to just pass in the entire path to save the image to (/path $replace(%path%,%filename_ext%,)folder.%%extension%% for example). If you then search for another album from within Album Art Downloader rather than starting from a track in foobar, you will have to right click on the result, choose Save As, and find the folder to save it to manually.
If you are using the file browser, use a relative path for the image, like the default of just "folder.jpg", for example. The browser will then look for that relative to the folder the audio file was in, and automatically populate that as the Save To location if you launch a search for it from there.
