Welcome!

Question and Error Comment: Question - Can this use piety with either the prayer option selected or the absorption pot method? Error - The overload settings only allow for the options of 0, 9, or 27 overloads (none of which is desirable).

I hope so :-)

Update: I fixed the problem! I downloaded the client under Programs Files (x86) and the Old School RS client under Users -> "computer name here" (default download locations). I resolved this problem by placing the OSRS files in the Program Files (x86). Don't ask me why the OSRS client...

"Unable to bind to the game client because of an IOException" also "Unable to attach to 64-bit process"

Update: I ran both as an admin and am now getting an IOException error message instead

I am having this problem as well and none of the aforementioned ideas had any impact in fixing the problem
