User comments on Android Central claim that Kies does not support Windows 64-bit. People with devices like Galaxy Note or Galaxy S3 can not update their devices via Kies because they are using Windows 64-bit computers. This also prevents them from handling basic functions like Outlook sync with Galaxy devices.
It doesn’t have to be so difficult. While I’m confident Kies will eventually catch up to the world of 64-bit operating systems, you do have some options today.
CompanionLink supports Windows 32-bit and 64-bit. While CompanionLink does not manage operating system updates to Samsung devices or music or videos like Kies, CompanionLink will keep Outlook on a 64-bit Windows computer in sync with any Samsung Galaxy series device. The CompanionLink package intelligently detects the bitness of your Windows operating system and adjusts accordingly. No user interaction or separate software to install.
