We are using GW 7, and GMS 2.01... I have had good luck installing Intellysync on many different types of pda's...we had Palm's in the past, however in the last year or so we have added quite a few phones using Windows Mobile 6.1 and 6.5. Intellysync is working fine on those systems using a Pocket PC client, and installing through Active Sync. However, I am not able to install the Intellysync client on the HTC Eris w Android OS...there is no desktop sync connection, and when I download the setup.exe for Intellysync to the phone it will not run it, says file type is not supported...any ideas on getting this to work? thanks!
