Updating a macro to 64 bit

There is a macro in the wx_Tools group of macros that I really miss and that's Paste at Mouse which only seems to work for 32 bit.

I tried to do some research on how to update it, but now my head is just spinning. I tried looking at the file: Win32API_PtrSafe.TXT but I'm lost.

Is there an easy way to do this, or can I hire someone to create the macro for me?

Thank You!
