Unable to install Maximo 7.5.0.7 Fix Pack after install Maximo 7.5 DEMO - x86-64

Question

I successfully installed Maximo 7.5 on Windows Server 2008 R2 64-bit with the defaults (WebSphere 7, DB2, Tivoli Directory). I'm trying to install the 7.5.0.7 fix pack but get this error after I ran install_win64.bat (Run as Administrator). This error occurs a few steps after "Database is ready for upgrade" checkbox.
CTGIN2076E: Exception Running WASThingClient method for task runConfigurationStep.
The CCMD_install.log said:

Answer 1

Make sure MXServer on the application server is stopped first.
Extract the fix pack to c:\temp\ to run the installer.
From a command prompt, run:
C:\temp>set skipwasvalidation=yes (this will create a set variable
to skip websphere application server validation)
On the same command prompt window run the install.exe (or
install_win64.exe for x86-64).
When you run install.exe, the Run
Configuration Step panel will offer the some options:
Check on Copy files now, but perform the installation configuration step later
Deploy application files manually later
Defer the Update of the Maximo Database
This will complete the install, deferring all automated actions.
At a command prompt, change to the c:\ibm\smp\scripts folder and run:
taskrunner.bat CONTINUE STOPONERROR
Run updatedb.bat from c:\ibm\smp\maximo\tools\maximo
Build and deploy the maximo.ear (c:\ibm\smp\maximo\deployments\buildmaximoear.cmd)
