Austin, Thanks for your prompt response. I tried to run MyApp.exe(64 bit one) using wine-1.1.16 and got the following error: ............................................................................................ Trying to load PE image for unsupported architecture (AMD-64) wine: could not load L"Z:\\MyApp.exe": Bad EXE format for MyApp.exe:PE32+ executable for MS Windpws (console). ............................................................................................ Is there any specific param related to 64 bit to be passed while configuring the wine or can it be configured as usual? Thanks, Yug
