Thanks for the input.... but it didn't work.
I created an archive folder on my desktop, and within it there is a directory tree locating the directories and files related to Crossover. So I've got
/Users/john/Desktop/Crossover/Applications/CrossOver.app
/Users/john/Desktop/Crossover/Users/john/Applications/Crossover/Quicken 2012/Quicken 2012.app
/Users/john/Desktop/Crossover/Users/john/Library/Preferences/com.codeweavers.CrossOver.plist
and so on. Complete backup including caches and Wine Files folder tree
Then followed the manual uninstall instructions exactly as written, deleted all of the originals I'd saved (above).
Download/install 11.0.3; then installed Quicken 2012 using the recommended settings (new xp bottle, etc).
Quicken runs. One Step Update is crazy. Quotes download (19 quotes) and Historical prices (16 of 25 symbols) and shows the current date/time. But every Financial Institution fails. Quicken is unable to establish an internet connection. Really it makes no sense since my 401(k) quotes downloaded.
So I tested some other features, like the More Info button next to the error messages. The built-in browser works fine and gets to the web. Same thing when I click the Quicken.com button.
And none of this happens running Crossover 10.2.
What else can I try?
