IntelVisualFortran Compiler 11.1, 64bit-systems, NONMEM7

dear NONMEM-users, It is one month that I try installing NONMEM on a 64-bit WIN7 system. First I understood that IntelVisualFortran Compiler 11.1 was necessary because good-old CompaqVisualFotran is not compatible with 64-bit systems. By installing IntelVisualFortran 11.1, it became clear that Microsoft software-development-kits (SDK) have also to be installed. After (seemingly) successful installation of SDK and IntelVisualFotran 11.1, the software indicates installation-command to be "ifort". However, when trying to install NONMEM7 via MS-DOS and typing: D: SETUP7 D: C:\nm7 ifort y link reg norec i unzip.exe nonmem7e.zip nonmem7r.zip ...compiler check fails, and "ifort" is not recognized, respectively. Since I am not getting further help from ICON, I wonder if other users have encountered similar problems. Generally, installation with new IntelVisualFortran Compiler seems rather complex, especially for setting the environmental properties. thanks for any idea about how to proceed best regards Markus -- Markus Joerger MD PhD Department of Medical Oncology Rorschacherstr. 95 9007 St. Gallen markus.joerger markus.joerger phone: +41-765591070 fax: +41-714946368
