OK...I worked around the issue. It turns out that Win7 with IE 11 will not properly download the file from the Cakewalk site. IE 11 on my PC doesn't know how to handle the naming convention used by Cake. It sees the file name as "NYCShowroomIRsSetup_1.0.0.0[1]." I'm guessing the brackets caused an issue...at least on my PC configuration. I simply switched to Firefox and had no more issues. Firefox sees the file as "NYCShowroomIRsSetup_1.0.0.0.exe."
Again, thanks for the help.
