Primavera P6 v7 Installing Web Services

Hi,

I am installing Primavera P6 v7 web serivces on a Ms Windows 2003 server machine but it gives error "error setting Java_Home environment variable" every time i run the oracle universal installer setup of P6 v7 web services. I have already installed Java JRE1.6.0_14 and set the JAVA_HOME variables in both system and user variables. I have also tried manually setting path of JAVA during setup but no luck so far everytime same error. I have been looking at the log file in oracle inventory folder but did not find any hint to resolve the issue.

Please help.

Regards,

Shahid
