I would suggest running the following to confirm that the private key (which setup was failing to open or create) does not already exist. If you are unable to run .ahk files by double-clicking, you can drag-drop the file onto a copy of AutoHotkey.exe (v2).
CODE:
#Requires AutoHotkey v2
if !DllCall("Advapi32\CryptAcquireContext", "ptr*", 0, "str", "AutoHotkey"
, "ptr", 0, "uint", 1, "uint", 16) ; PROV_RSA_FULL=1, CRYPT_DELETEKEYSET=16
throw OSError()
else
