HTC Sync cannot detect the phone if iTunes installed
If any of you is having trouble to let HTC Sync detect the phone, try to rename the "iTunes" folder in your "My Documents\Music" folder.
When I bought the phone, I installed the HTC Sync v3.0.5517 (which was on the SD card and newer than the online version) on my Windows 7 x64 SP1 e never could see it detected by the software. Every time I launched it, the notification icon showed that the phone was detected and after 2 seconds disappeared (htcUPCTLoader.exe also disappeared from task manager).
I tryed the software in a WinXP Virtual Machine and it worked fine, so I decided to contact the HTC Support in order to know if there was some incompatibility with Win7 x64 SP1: the told me that the problem was my PC
After a few search, I found a similar problem in another forum, and tried to rename the iTunes folder, and I finally got HTC Sync starting and synching like a charm. The problem is when the software tries to detect our iTunes playlist in order to show them in the Media synchronization.
I replied back to the HTC Support telling them this issue, hoping that they will fix it.
