yep, you need to run the client as 64bit build instead of the 32bit version provided by the developer.
on there github they offer a pre-compiled binary and flag it as 64bit version.

but that is not correct,  they used my compiled client because it has less false flags on av scanner.
it is not a 64bit build. 

if you wanna use Trollcoin on your Computer you have to build it on your own as 64bit version
otherwise the client will crash because of its use >4gb ram.

or wait for the developer to build and publish an pre-compiled binary for windows as 64bit version.
