AFTER DOWNLOADING:

#1
Copy "iOros.exe.config" to ABM Client Workstation folder:
C:\Program Files\SAS\Activity-Based Management Solution\Client\Bin\

#2
Copy "probody.js" to ABM Client Workstation folder:
C:\Program Files\Common Files\SAS\Activity-Based Management\resources\en\html\scripts\

If the above path does not exist, use Windows Search (Start >> Search) to look up "probody.js". 
Once you've found it, go to the folder and update the "probody.js" file with the version from the hotfix.


NOTE:
If you didn't install ABM on the default path, modify the path accordingly.
