PowerBuilder 11.2 COM saveAs PDF issue (Windows 7 64bit)

Hi,

I have a COM component build by PowerBuilder 11.2. When I tried to save as PDF, its returning -1 and create 0 byte PDF. But the same code working fine on the classic application and generates PDF successfully. I have the "Sybase DataWindow PS" installed in my machine. Any one have any idea why it is not working when it is tried to SaveAs PDF from COM component? all folders have appropriate read/write permission as well.

System details below

PowerBuilder 11.2

Windows 7

GhostScript 8.71 64bit

Any help???

Thanks,
Senthil
