Oh Yes!!! I got it fix! the solution came when I was trying to install and run MobileMaster instead. Then it prompted me something about DEP. And when I changed the settings of DEP, MyPhoneExplorer ran smoothly!
Praise God! Thankfully I tried MobileMaster and got MyPhoneExplorer working! Haha! Sadly I will not be using MobileMaster. MyPhoneExplorer is my first choice!
The solution is very simple, when installing run the install file as "run as administrator" in vista. It hangs because a normal user is trying to alter files in the system32 map, vista does not allow this.
