We recently moved from a really old version of Sage to Sage 50.
Initially we couldn't get Sage to run at all, then found that disabling Avast for a few minutes allowed it to do so. Further investigation led to me adding all things Sage to the Avast exclusions section, still no luck. I'm guessing(hoping) that someone out there has had the same issue and there's a simple fix! Any advice gratefully received.
Cheers
John
