I'm having a similar problem....sort of.... I have an iPAQ, which I sync using ActiveSync 4.7. I just got a 7100i and am trying to install the desktop management software. When I do, I get an error message saying that there is a newer version already installed..... and it aborts the installation. So, it sounds to me like 1.) the desktop installer is attempting to install an older version of ActiveSync? and 2.) it's not possible to run two versions of the same software from different folders for different purposes?
I just got the 7100i yesterday, but have plenty of gadgets and phones so I thought I'd be able to figure this out. WRONG!
I've searched and haven't found anything remotely like this issue on any thread so far. I apologize if I missed something tho.... Could someone possibly help me around this...or point me to somewhere this is discussed? I need to be able to download some software is the main reason for needing the desktop software. I SO appreciate ANY help!!
