I installed APCC 1.8.1.1 on a Windows 7 x64 machine and the for update section showed that "The latest version of APCC is: 1.8.1.1"
I installed the same APCC version on my Windows 7 x64 laptop and noticed that "The latest version of APCC is:" The version number is missing. Reinstalled the same package but still the same result.
