If…

1. You installed Oracle XE but you cannot launch APEX or start up oracle.exe process

2. Your computer joined Windows domain

3. You installed it using Domain account

Very likely, it will try to install it using domain authentication which it may not work.

Therefore, the solution is to:

1. Create a local user with admin right

2. Log in using that local user and set regional setting to en-US

3. Install Oracle XE

4. Go to c:\Oracle\app\oracle\product\10.2.0\server\NETWORK\ADMIN\sqlnet.ora and remove the line that said SQLNET.AUTHENTICATION_SERVICES = (NTS)

Many times, I installed SQL Server 2008 and failed with just the error message “Access Denied”. One of the cases I found is that my Administrator account doesn’t have SeDebugPrivilege especially when GPO policy is in effect. I still don’t understand why anyone should be admin but cannot debug things :(
