get Poser's install directory from the windows registry While this is actually mostly redundant
thanks to Poser's AppLocation() it does show how to access the registry to read keys / data.

import winreg as reg


class _REGISTRY:
    def _find_poser_win(self, version):
        poser = r"SOFTWARE\\Poser Software\\Poser\\Poser %d" % version
        with reg.OpenKey(reg.HKEY_LOCAL_MACHINE, poser) as key:
            if poser.endswith(str(version)) and key:
                return(reg.QueryValueEx(key, "InstallDir")[0])

# example code


installdirs = []
for version in (10, 11, 12):
    print(f"testing Poser {version}")
    try:
        installdir = _REGISTRY()._find_poser_win(version)
    except:
        installdir = "Not Installed"
    if not installdir in installdirs:
        installdirs.append(installdir)
    print(installdir)
