Windows registry PermissionError

[Mike Dewhirst]

I'm trying to copy a value from HKLM to HKCU for application rollout via bulk installation by an administrator but individual Windows user setup.

Getting this ...

Traceback (most recent call last):

    curegistry.setvalue('Country', anz)

    return wr.SetValueEx(self.select(), vname, 0, 1, value)
PermissionError: [WinError 5] Access is denied





import winreg as wr


class Registry:

    def __init__(self, computer=None, hkey=None, sub_key=None):
        # computer is None means this computer
        self.computer = computer
        self.key = hkey
        self.sub_key = sub_key

    def connect(self):
        return wr.ConnectRegistry(self.computer, self.key)

    def select(self):
        # also tried OpenKeyEx()
        return wr.OpenKey(
            key=self.key,
            sub_key=self.sub_key,
            access=wr.KEY_ALL_ACCESS + wr.KEY_WRITE,
        )

    def query(self, vname):
        return wr.QueryValueEx(self.select(), vname)

    def setvalue(self, vname, value):
        return wr.SetValueEx(self.select(), vname, 0, 1, value)

if __name__ == "__main__":

    lmregistry = Registry(
        hkey=wr.HKEY_LOCAL_MACHINE,
        sub_key="SOFTWARE\WOW6432Node\XXX Technology\AppName",
    )
    print(f"\n{lmregistry.sub_key}")
    anz = lmregistry.query('Country')[0]
    print(f"\n{anz}") # works fine

    curegistry = Registry(
        hkey=wr.HKEY_CURRENT_USER,
        sub_key="SOFTWARE\XXX Technology\AppName",
    )
    curegistry.setvalue('Country', anz)  <<<<< BOOM <<<<<
    ...

Any hints appreciated.

Cheers

Mike

But I would not have been surprised if it worked here but not in the field where users are firefighters and definitely not administrators and cannot install software on their workstations.
