For the ease, I want to use your Installation Assist that downloads Windows 10 for me and installs it, but it does not allow me to select the location to install to, good job. It's unusable for me, unless there is a way ... Is there any way besides downloading the image by myself?
Hi you can download Windows 10 .iso file from the Microsoft website or check this KB article for more info about Windows installation. Please let us know if it's not that case.
Now you want to set directory path for your install, so that your app get installed in the desired location. In order to do this feedback, you need to follow steps as: Right Click on your Setup project -> View -> File System. Then Click Application Folder, open property tab.
