AFTER DOWNLOADING:

This hotfix requires you to "slip-stream" some updated files into your original setup files.
So if you haven't done so already, please find the original ABM 6.3.1 CD and copy its entire content to a shared/local folder somewhere. 

Here are the files you need to update on your ABM 6.3.1 Setup Folder:

#1
sas.abcm.ServerDiagnostics.dll 
goes to
"SetupServer\Program Files\SAS\Activity-Based Management Solution\Enterprise Server\Diagnostics"

#2
sas.abcm.Components.dll 
sas.abcm.Import.dll 
go to
"SetupServer\Program Files\SAS\Activity-Based Management Solution\Enterprise Server\SasSolutions\ABM\services\bin" 

#3
sas.abcm.DbSetup.exe 
goes to
"SetupServer\Program Files\SAS\Activity-Based Management Solution\Enterprise Server\bin"

#4
Model_Create.sql
goes to
"SetupServer\Program Files\SAS\Activity-Based Management Solution\Enterprise Server\Database\Oracle"

---------

Now when you install ABM Server from this setup folder, the updated hotfix files will automatically be applied to your server.
