Second that. And using workarounds to restart explorer.exe isn't acceptable from a user experience perspective. All applications are installed in such a way that if explorer.exe needs to shutdown but if it can't then we can inform the user that they need to do a reboot to complete the installation.
The way it is now with the current Creative Packager, I can't package/deploy Adobe Photoshop CC. I did however notice that a much earlier build of Creative Cloud Packager, it didn't terminate explorer.exe but unfortunately I can't use that build and have to rebuild it using the current packager.
Does Adobe have any plans on addressing this? Or at least give us an option via the MSI installer that it doesn't kill the explorer process during install and uninstall.
