For those of you who were experiencing the "1628" error with Quicken 2004 under Crossover Office 2.1, Crossover Office 3 appears to solve the problem. I just did an install and it went flawlessly:
start cxsetup
insert quicken 2004 deluxe cd
select quicken from the cxsetup supported apps list
tell it to use the cd in the default location
and it all just worked! 😉
Once installed, it works quite well. There are lots of cosmetic things, like text overflowing buttons and such, but so far all the functionality (including registration and online update) is there
