Running Ubuntu 7.04 (Feisty), I tried older versions of MYOB Premier. Bottle used win98 with DCOM98.
Both 5 and 7 loaded and ran their sample company - Clearwater with limited degrees of functionality. Mostly as described in known issues and Tips and Tricks. I have no printer connected so could not test printing. Save to file as .pdf worked well, however, and Alt+letter allowed tab changes within most screens.
Version 9 loaded but failed to run, even after loading IE6 into the bottle.
The program is now up to Version 11, with 12 due next month. MYOB has also dropped support for win98, etc at this time.
I consider this accounting program has too many issues to continue chasing - considering the degree of interest that it has raised in codeweavers (6 or 7 forum threads in 4 years).
An accounting program needs to be usable without too many work a rounds
I may try these again on the next Ubuntu or other disro if I get time in the future.
