Multiple GW clients on same PC

I am trying to get 2 separate GW accounts to open on the same desktop, I used to use gwx2 but for whatever reason the new GWxINF version doesn't want to work on my computer and the old one refuses to work either. Someone told me Sandboxie would do it but I keep getting an error message that the file I am trying to open with Sandboxie is too large. Could anyone shed some light on this please?

Try GW Multi-Launch or KSMod. Links are below.
