Windchill version upgrade cps error

[永贵_10723545]

hi，everyone

     while upradeing windchill 12.0.0.0, I try to install cps 12.0.2.17 , but there is an error in this progress.Here is the logs.

The XCONF file file:/C:/ptc/Windchill_12.0/Windchill/wex/packages/com.wincomplm/wex-kernel/wex.xconf referenced from file:/C:/ptc/Windchill_12.0/Windchill/codebase/wnc/Foundation/Windchill.xconf, line 22 cannot be found.

    I cant find the wex.xconf,it really didnot exist, anyone know how to handle this problem?thank you so much!

try to comment that line in Windchill.xconf ,save and run an "xconfmanager -p" , restart the server and retry
