Halion 6 download

Hi, I just bought Halion 6 and I am currently downloading the Steinberg Download Assistant (100MB) but, notwisthanding my 130MB connection its speed is around 81kB/sec (!) and using an external download manager (JDownloader) did not help me.
Now my question is:
Is it possible to use Steinberg Download Assistant to download H6 on a different PC (with a faster internet connection), saving it on external HDD, and later to install it on the PC with the e-lincenser which does have an internet connection but far slower then the other pc?
Please let me know,

Yes, the downloader is just downloading a regular installer.
