Apologies, I had to remove your screenshot as it was showing all of the serial numbers which I would not advise as you are in a public user to user forum.
If you wish to show list of products then please blacken out the serial numbers listed on top of the products and re-upload screenshot..
Looking at the file sizes shown in your screenshot I suspect at least some of them are links to one or more Download Managers, whose purpose is to download and check all the actual installation files before beginning the actual installs. In other words, they are NOT the installation files, merely a device to control the downloads and installations. As such, they may require more “time to run” than the user might expect.
So, how much time did you allow each “file” to run for before deciding that the install had failed?
Well I am half blind so I didn't notice the button that said "Download" on the right of the page, and I kept clicking the link on the left instead haha
