Hello Stahlin, I can confirm that it does indeed work with RCM 2.7, but I have not tried it with APRM as yet.
Many thanks for your efforts.
Are you using a digital version of SSRW Stahlin? I have installed APRM without a problem in the past using the CD-ROM media version of SSRW. As you probably already know some older mods don't work with the digital versions because of the different game directory structure.
I have downloaded AXPRM from the mainpage as standalone and it dont work. Furthermore the installer is in hungarian, which 99 % of the world dont understand.
