Error 1603 is a general Windows error while installing programms on windows.
I searched our issue database: Often the reasen is the installation of CodeMeter Runtime. You could try this:
Uninstall CodeMeter Runtime manually from Windows Apps/Features
Reboot PC
Restart AS installation
That should hopefully fix it.
If this does not fix the issue, please contat your local B&R Support.
I’ve seen this error before. During the installation of AS6, an older version of CodeMeter was uninstalled. Reinstalling the current version of CodeMeter didn’t fix the issue in my case, but maybe in your case it could help already.
You could also try installing the current Technology Guarding version as well, if you haven’t already:
Once you’ve installed the current TG version and CodeMeter and restarted your PC, you can try installing AS6 again.
Additionally:
When you extract the zip file for AS6, please check the “Properties” of the zip file first. There’s a “Security” setting there. You can check the box for “Allow” in case there might be an access issue on your end.
