Running into a "Low Memory" error?

The most likely cause is a header option called, "LargeAddressAware". By default, Ultima Online's LargeAddressAware option is set to only be able to access the first 2GB of memory on your machine. This means, even if your computer has 64GB of memory, if the first 2GB are spoken for by other programs/services then UO wont be able to access enough memory to run and it will give you an error.

An .exe has been developed by a third party to make this process extremely easy/painless and you can request this .exe by sending me a PM through Discord. We have had great success with the .exe method, but you should be warned that downloading a 3rd party .exe from a stranger online is never advised!

The following image describes in further detail what LargeAddressAware is, and how to enable it by hand (without the .exe) so that UO can access more memory!
