I want to uinstall multiple Trend Micro officescan offline clients. and resinstall the same. Trying the same in silent mode as while uninstalling the software, process window appears due to which user will try prompt with lot of questions. I am trying this activity in silent mode so that users may not be aware about the backgroud process. I am trying with PSEXEC but i am unable to find the switch to execute NTRmv.exe in silent mode .
