Running Steinberg Download Assistant and other updaters from a batch file

I’m trying to load the Steinberg Download Assistant and other updaters from a batch file since there are so many these days. I’m most of the way there but only Aquarius and the UAD Monitor actually open, although the iZotope product portal shows up in the tray, but the program window does not show up. The Steinberg Download Assistant along with the others does not open. I do get CMD windows for each of the programs showing the CD command has occurred. Here’s the batch file:

Any help would be appreciated!
Thanks

Anyone?

I don’t know if this will help in any way, but I seem to be using a much simpler batch file format (less stuff between the command lines):

“C:\Program Files (x86)\Arturia\Arturia Software Center\Arturia Software Center.exe”

“C:\Program Files (x86)\ToonTracks\Toontrack Product Manager.exe”

“C:\Program Files\Native Instruments\Native Access\Native Access.exe”

“C:\Program Files\Waves Central\Waves Central.exe”

Hi. Thanks for the reply. I tried that, and it does work, but they only open sequentially after the first one runs and is closed, then the next one runs, etc.
I was trying to get them all to open at once and get it over with. But this is a good start.
Thanks.
