Well, at first glance, I can see at least one problem with your AdAware install. Your code for installing AdAware references an "AdAware" folder: start /wait %systemdrive%\install\Applications\AdAware\aaw6181.exe /s However, your screenshot of your directory structure indicates that the directory is actually called "adware" not "adaware". So, that would definitely cause a problem. As far as PowerToys is concerned, it appears that you merely forgot to include the "applications" directory in the path statement for your install code: start /wait %systemdrive%\install\PowerToys\TweakUI.msi /qb The above path does not include the applications directory. Since the applications directory is part of the path, your installation fails. Some advice: Anytime one of your installs fails and complains about not locating a file, etc, triple-check your path AS WELL AS your filenames! Hope this helps. - Ravashaak
