Successful installed, by Burn, due to registry editing has been disabled

The root cause of the issue is the registry editing has been disabled. I enable it via gpedit.msc and make some registry clean up before start a new oracle database installation.

Below is the detail for the installation:

1. Installation dir --> C:\oraclexe
2. Database version --> 10g XE
3. Create 2 user as requested : a) CAS/cas123
b) SYS/password

Command used to create user

1. create user CAS identifed by cas123;

2. grant connect, resource to CAS;

3. connect CAS/cas123

New connection created in SQL developer

connection name: testcas
username: CAS
password: cas123
hostname: localhost
port: 1521
SID: xe

Connection test status : success
