Hi Xiaogang
I had similar problems when I installed v7.1 alongside v6.3.
The installations share a folder: C:\Documents and Settings\YOUR LOGIN NAME\Local Settings\Application Data\Metrowerks.
This folder is updated each time you launch and IDE and it can get confused.
I deleted the contents of this folder and then relaunched v7.1 and the USB Tap option reappeared.
It is a pain that you have to redo your project settings but it worked for me.
Good luck
Regarding the "ROHS USB TAP Update.exe" error it's almost certainly a bug in the Update executable itself, and best ignored as clearing out the above folder will most probably solve your problem.
