Oracle 10g XE to 11g XE upgrade: gen_inst.sql does nothing.

Question

I am trying to upgrade from 10gXE to 11gXE;
I logon to SQL Plus "conn sys as sysdba", and execute the gen_inst.sql procedure.
Quote: Connect to 10.2 XE database as SYS user and run gen_inst.sql. This will generate install.sql, gen_apps.sql and other .sql files. The files will be generated in the folder containing gen_inst.sql. End Quote.
However the procedure completes immediately, and does not generate any of the files described.
If I execute @(folder path)\fred.sql (where fred.sql does not exist, I get a message that the sql proc is not found, so I know that it finds the procedure when I try and execute it.
The following is a copy of the command window.
SQL*Plus: Release 10.2.0.1.0 - Production on Sat Jan 14 11:24:06 2012

Enter user-name: sys as sysdba

Connected to:
Oracle Database 10g Express Edition Release 10.2.0.1.0 - Production
SQL> @c:\temp\gen_inst.sql
SQL> @c:\temp\fred.sql
SP2-0310: unable to open file "c:\temp\fred.sql"
SQL>None of the defined files , "install.sql, gen_apps.sql and other .sql files" are created.
If it try and run gen_inst.sql from within SQLDeveloper (2.1.1.64), after haveing connected as sys/sysdba, the procedure runs for several minutes, and creates some of the listed output files, before it finally crashes with :
Error report:
ORA-20000: ORU-10027: buffer overflow, limit of 1000000 bytes
ORA-06512: at "SYS.DBMS_OUTPUT", line 32
ORA-06512: at "SYS.DBMS_OUTPUT", line 97
ORA-06512: at "SYS.DBMS_OUTPUT", line 112
ORA-06512: at line 5
20000. 00000 - "%s"
*Cause:    The stored procedure 'raise_application_error'
was called which causes this error to be generated.
*Action:   Correct the problem as described in the error message or contact
the application administrator or DBA for more information.How do I get the script to run correctly in SQL Plus?

I might just be a problem with spooling result files to the wrong location or calling them with the wrong path, because the script anticipates to have everything in the same local path...Interesting point, and definitely worth a try.
The quote part in op, from relevant doc section, seem to say differently. Looking through the script it would seem that files are actually spooled in working path (e.g. current dir when sqlplus is started) instead of folder where script exists.
"The files will be generated in the folder containing gen_inst.sql."
http://docs.oracle.com/cd/E17781_01/install.112/e18802/toc.htm#CIHCDCDH
I think file permissions should be considered still, if on Win 7 (or other OS with some level of least privilege policy implementation).
Edit:
A small test on windows platform showed that files are output in cwd from where sqlplus is started and also that saving files in c:\temp worked fine.
