I am interested in the experiences developers have had with the USB ANT stick and software running on MS Windows 7 (especially the 64-bit version). Our Windows application runs on XP and Vista (32-bit anyway). Out 32-bit software without the ANT DLLs runs on 64-bit Windows 7, but when the support for ANT and its DLLs is added it installs okay but refuses to run. Windows does issue a "ding" sound but nothing else--no error message in particular. When checking compatibility, Windows 7 says the application is incompatible (but does not say why). I will try the XP compatibility mode, but first I have to upgrade beyond the Win7 Home Premium version. Will there be 64-bit DLLs for USB ANT stick support? Needless to say, I am quite frustrated by Win7 (having other bad experiences as well).
