I think you have a 64Bit installation of J.River Media Center. I've made small changes to access the registry on 64Bit. Please test the attached version.

I'm not using JRiver at the moment but I shared a download link on their forums. Thanks.

[jachin99]

Any way you can upload that attachment? It was lost in the forum outrage. Thanks.

[kgschlosser]

I re uploaded it to the first post.

Sorry, I should have been more specific. I have the 64 bit version of JRMC 25 installed. Thanks.

I tried looking through this post and doing it on my own but I still get a JRiver not installed message. Here is what I have for enumerating the registry

Code: Select all

def _get_reg_value(path, key):
    d = _read_reg_values(path)
    if key in d:
        return d[key]

    return ''


def _read_reg_keys(key):
    if isinstance(key, tuple):
        root = key[0]
        key = key[1]
    else:
        root = _winreg.HKEY_LOCAL_MACHINE
        key = 'SOFTWARE\\Wow6432Node' + key

    try:
        handle = _winreg.OpenKeyEx(root, key)
    except _winreg.error:
        return []
    res = []

    for i in range(_winreg.QueryInfoKey(handle)[0]):
        res += [_winreg.EnumKey(handle, i)]

    return res


def _read_reg_values(key):
    if isinstance(key, tuple):
        root = key[0]
        key = key[1]
    else:

        key = 'SOFTWARE\\Wow6432Node' + key

    try:
        handle = _winreg.OpenKeyEx(root, key)
    except _winreg.error:
        return {}
    res = {}
    for i in range(_winreg.QueryInfoKey(handle)[1]):
        name, value, _ = _winreg.EnumValue(handle, i)
        res[_convert_mbcs(name)] = _convert_mbcs(value)

    return res


def _convert_mbcs(s):
    dec = getattr(s, "decode", None)
    if dec is not None:
        try:
            s = dec("mbcs")
        except UnicodeError:

Removed

[kgschlosser]

I updated the plugin on the first post. It should work now.

[jachin99]

That did the trick!!! Thanks
