ThroughFocus3 is built on Windows7 and Mac OSX 10.9. Users have encountered problems attempting to run it on older Windows systems, including WindowsXP. The following two patches have been released by Exelis, the makers of IDL, to enable ThroughFocus3 and other IDL runtime applications to run on older systems. These are only necessary in cases where ThroughFocus3 crashes within the first few seconds of launch.
This patch is provided by Exelis Vis to enable the distribution of “runtime applications.” If Windows crashes abruptly and you are running 64-bit Windows, please install this patch.
