Sometimes during install of some product you may face the error “The process cannot access the file because it is being used by another process” and your installation fails. In such situation you can do following things to eliminate the error:
1. Check the log created by the product installer. Usually they are located in the temp directory. Log file may tell you which file is used by other process. Using Process Explorer(Tool from Sysinternals) you can check that the file is used by which process. Then close that process and start your installation.
2. If you are installing using shared folder from remote machine as media, then check if_ISDel.exe is running. If it’s running then kill that process using task manager. Sometimes this helps.
