Looking for 64 bit version of Declare Function GetUserName

I am using getusername function to use Windows login for security. However, when I tried to use the mdb on a 64 bit setup I get the following error msg.

The code in this project must be updated to 64bit systems. Please review and updatet declare statetments and then mark them with the PtrSafe atribute.

What do I need to do this?

Declare PtrSafe Function GetUserName Lib "advapi32.dll" Alias "GetUserNameA" _
(ByVal lpBuffer As String, nSize As LongPtr) As Long
