Hi Lisa
1)When my app run these command lines following, my app gets a message error “olistener is not an object”:

SET REPORTBEHAVIOR 90
olistener=NULL 
DO reportoutput.app WITH 5,olistener
olistener.listenertype=1 && error message, “olistener is not an object” happended at this line

2) What does your CONFIG.FPW look like?

STATUS BAR = ON
CLOCK = STATUS 
ALTER = ON
NEAR = ON
BELL = ON
ESCAPE = ON
CATMAN=OFF
SAFE=OFF
COMMAND = RESTORE MACROS FROM DEFAULT.FKY
COMMAND = release wind command
_REPORTPREVIEW="reportpreview.app"
_REPORTOUTPUT="reportoutput.app"

3) How did you install the runtime files for 9.0 on these computers? How did you do the upgrade of GDIPlus ?
I use the *.msm that include with VFP9beta setup file, they install with my app by Installshield ( similar VFP8). Eventhought I copy overwite every file “GDIPlus.dll” exiting on my computer with new GDIPlus.dll (1700352 byte)

However, if I install the "prerequisite setup" of VFP , it will OK with WinXP (Win98 still error).
Now, I find the way to solve the problem for WINXP
