Oracle Fusion Middleware 11.1.1 Forms & Reports Next Errors

After I solved yesterday the first error during the linking process of the Oracle Fusion Middleware 11g Forms & Reports the next error comes up :-) Now at the configuration steps, the first configurations like creating Managed Servers for Forms & Reports, Deploying of the Enterprise Manager aso. was successfull, but at the configuration step "Creating ASInstance" a failure comes up :-(

The Installation Logfiles just say:

An internal operation has failed: The oracle instance is not empty. Select a different location or remove the instance at this location.
. . .
Caused by: oracle.as.config.exception.LocationAlreadyUsedException: The oracle instance is not empty. Select a different location or remove the instance at this location.

???? That's a fresh new Installation, how the Instance can not be empty?????

So, now I'm trying with Oracle Metalink to solve this problem, let's hope ....
This blog entry will be continued, depending on the performance of Metalink :-)
