Most 32-bit Windows applications will run just fine under 64-bit Windows, provided that the operating system version (XP, Vista, 7, etc) is supported. Such is the case with WeFi, and the developers do not specify 32-bit/64-bit support under the system requirements. Thus, the 32-bit version should install and operate normally.
According to TechTracker my download of WeFi has an update but when I try to download the site states that the update is only available for 32 bit Vista. I am using Vista Home Premium 64 bit. Can you give me some advice? My version is 188.8.131.52 of WeFi.
