I have a BB 7520. I have read the other postings and had no luck with their suggestions. I am running desktop software 4.2 sp1 on a vista business machine. I had to install palm desktop and afterwards the blackberry could not be detested. I have uninstalled the device, no luck. I have uninstalled the Desktop Software, no luck. I have also uninstalled the the driver from the device manager. I tried deleting the folders from common files but it says i do not have permission even though i am a full administrator on the computer. I do not know what else to do. Are there hidden files in the registry that need to be deleted? I have Desktop Manager 4.2.1.8 with Handheld v4.1.0.273 on a Vista Business machine. Any ideas would be great. Thanks.
