CCS5.3 update issue

hi,

       The OS for install is win7-64bit . When installing I disable my norton and the firewall. The InstallJammer log is attached:

 2047.InstallJammer Registry.rar

       I got a update issue after installed the CCS5.3. When I click the "check for update", CCS will report  "The operation cannot be completed.  See the details." and the detail is like below:

Cannot complete the install because one or more required items could not be found.
  Software being installed: Blackhawk CCSv5.3 Emulation Update 5.3.0.340 (com.bh.ccstudio.emulation.win32.feature.group 5.3.0.340)
  Missing requirement: Blackhawk CCSv5.3 Emulation Update 5.3.0.340 (com.bh.ccstudio.emulation.win32.feature.group 5.3.0.340) requires 'com.ti.ccstudio.installer.win32.feature.group [5.1.0,5.3.0]' but it could not be found

 I remember I can do it before with a same ccs copy in windows XP.

Another issue:

if I directly use the ccs version without any update. It can connect with my USB560v2 emulator(USB), but after connected and click the "stop" button or directly close the debug windows by click "x", the computer will reboot !!! (if not be connected with the emulator, this issue will not happen)

Any idea about it? Thank u!

Maybe I can use ccs5.4 for fixing this issue? but I'm not sure if the licence is common for 5.4 and 5.3?
