content: I can understand what you guys are saying there @glassuser and you, I did removed the program from control panel.  Cleaned the registry for all entries regarding the specific program in CLASSES_ROOT, CURRENT_USER and LOCAL_MACHINE.  We transfer from the network drive the local installation files for the program.  Double checked control panel and the program was not showing on the programs list.  Then I rebooted the computer.  When the computer rebooted, the program was back on the programs list and the local installation files had dissappeared.  The deep freeze install was not present on the computer, the IT of the institution I was dealing with, also thought about it but confirmed it wasn't the case.  Didn't check the filter.  But when the computer rebooted the program showed installed again.
