question:  Trying to install Adobe Premiere elements 12. When it gets to "Installing required Shared Technologies" stage it gives errror "Setup has detected that Adobe Bridge CS5 (Bridge.exe) is currently in use. Please close all running exe(s). Nothing is running when trying to install this, have been through this process several times. Found undertroubleshooting to delete files PDAppFlex.swf and PDAppFlex-app.xml and have done that as well. Any help will be greatly appreciated
