    I need to run an application that was designed for windows xp (should run with windows 10). I was hoping I could do so with Parallels and Windows 11 Arm version on my M1 Mac.
    Unfortunately I'm getting a system error that irprops.cpl file is not found. I googled and it appears to be a windows file typically stored:
    c:\\windows\system32\irprops.cpl

    Anyone know if there is a way to get this file loaded so I can use this old app? Or is this a limitation of Arm version of windows or parallels?

    thanks

    I found the solution.
    Check the SysWOW64 Folder (For 64-bit Systems)
    If you are running a 64-bit version of Windows, a 32-bit version of this file is named btprops.cpl.
    1. Navigate to: C:\Windows\SysWOW64
    2. Search for btprops.cpl.
    3. Copy this file and rename is as irprops.cpl
    4. Move this file to the folder of the application you need to run
