Dear Sharmeen,
I have HYSYS 3.2, when I came to open one hysys file it shows one message that " the build 6728 is not opened by 5029" It means I have hysys belongs to build 5029 & I try to open is of advanced version belongs to build 6728. So will you please help to open the newer version file with my old build.
Thanks & Regards,
Abdu
