Running Xandros 2.5 with CXO 4.0
Q2005 Premier from the distribution CD installed without problem for me if I selected the "install unsupported" software option from CXO's install screen and then browsed the "other .exe file" dialog to
/(cdrom)/DISK1/INSTALL.EXE
Using either CXO's "Quicken" install menu entry or pointing "other .exe" to SETUP.EXE on the root of the CDROM resulted in failed installs.
The report features and screen redraws work somewhat better than did Quicken 2004 under CXO 3.01. The only real issue I notice is that occasionally the reminder for the automatic backup "feature" enters a continuous loop condition which eventually results in an out of memory error. Data files do not appear to be damaged but I work around this by setting the reminder to backup to "0."
