TWS (most of it) is downloaded to your computer every time you run it, unless you use the "installed" version.Quote from Koppanyi:
It's possible, but I cannot connect to TWS because I didn't installed it. I ran it directly from the site.
Quote from Wayne Gibbous:
So it still runs on your machine and needs a good java install.
There has been nothing wrong with the IB websites all day, that I have seen.
Try clearing your java cache.
