It's more than just SSE4, there's also pclmul and AES. Also washed down iteration, such as SSE4.a won't cut it.
Thanks for the explanation. Do you have a recommended list of proccessors? (so I can buy one that will work well next time)
Perhaps "not installed" would be a more appropriate phrasing. Basically, running Armory by doing:
python ArmoryQt.py
Btw, noasm works great!
This means you need to delete .lmdb mirror wallets in your Armory datadir.
I am not seeing this error any more. This tip will be helpful if it comes up again.
Thank you so much for clearing this up.
