Hi Adriano,
I do see 19.5 upgrades posted to the account for the machine Adriano-PC2. You will need to install the upgrades to bump up the existing 19.0 licenses to 19.5.

If you have any further issues, please email support@sidefx.com.

Just an FYI! Every Indie subscription comes with a supplementary license to install onto a secondary computer, or to work in a dual-boot setup. www.sidefx.com/faq/question/466/

Good news! That's what I was suspecting which is why I asked for the output of uname -ar.
you can grab the 32bit installer and use that for now. Enjoy!
