Uninstall of workstation setup removed accpac.exe from server!!!!

We are re-purposing a PC which would no longer be used to access Sage 300 ERP so uninstalled Workstation Setup, Intelligence reporting, andUpdate Advisor.  That process also removed accpac.exe from \Sage 300 ERP\Runtime on the server.  We can no longer access Sage 300 ERP from any workstation.  I am looking into restoring from last system backup but am wondering what else might have been deleted.  Most important is that I need to know how to prevent this in the future when other machines get re-purposed.
