The current AFGROW release (V4.12.15) was built as a 32 bit application for VISTA and XP. Under 64 bit Windows 7, it will try to install itself in the Program Files(x86) directory. However,only the AFGROW and NASGRO database directories will be copied to this location. The work-around is to copy all of the files in the AFGROW directory from a VISTA or XP machine to the AFGROW directory on the Windows 7 box. In order to save user-created input files, it is necessary to install MSXML 4.0 (see the blog entry, also under tips and tricks). To use AFGROW COM capabilities, the afgrow.tlb file must be registered manually.
AFGROW won’t show up under your list of programs to run, but you can copy a shortcut to your desktop. This should not be a problem with the upcoming AFGROW release (V5.01.16)
