Oracle WRAP not working: empty output file SOLUTION !

SOLUTION 1:

check the ORACLE_HOME is correctly set
(eg: set ORACLE_HOME=D:\oraclexe\app\oracle\product\11.2.0\server)

SOLUTION 2: 

try to run the wrap utility as administrator 
(executing CMD.EXE as administrator)

Note: this procedure should only be nedded for the 1st time, because of the missing dirs as reported @solution3.

SOLUTION 3: 

go to your ORACLE_HOME directory, and verify you have those directories "log\diag\clients" 
if not create them!

(eg: D:\oraclexe\app\oracle\product\11.2.0\server\log\diag\clients)

SOLUTION 4: 
checkout the (almost hidden) log file under:

C:\Users\<user>\Oracle\ORADIAG_<user>\DIAG\CLIENTS\USER_<user>\host_??????????_??\ALERT\LOG.XML

(obviously remeber to replace <USER> and host_??????????_?? with your own values)
