I don't think that was the situation in my case which appeared on a 1462 to 1463 upgrade as I have set my preferences to run MM as Admin (gets over any issues with script installs).
Also like you I had installed all the extensions for all users (as far as I was aware :-? )
But it does seem to be linked with the disappearing extensions problem.
I have now changed to portable install and that issue seems to have gone away.

Ludek, I don't understand either. ;)

My guess is:

- during first install of MM4 I'm sure I installed as Admin
- when installing skins or whatever add-on, again, I'm sure I always installed for all users
- [b]BUT[/b] during upgrades to some 4.0.x version it's very possible that, instead of dowloading the file and installing as admin, at least once I just clicked on the DL link and run the program, so no admin privileges.

Now, what happens in this situation? MM remember my first install as admin, or "get confused" and don't know exactly if it's an installation for all or for one user only?

I don't understand one thing:
If you always install addons for all users how can you see addons listed twice (for 'All users' and 'Current user')?

So I am asking again, are there any steps to repro? i.e. Can I download an addon and get to the state you have observed?

In case there are no steps to repro then I guess it is something that remained from the earlier versions. The addons handling have been changed in MM4 so that users could install addons also without admin rights, so I guess that If you uninstall one of the duplicate addons (current user / all users ) that it uninstall only the corresponding instance, isn't it?

Ludek,

I don't know if it helps, but I just checked Tools/Extensions and i have ALL my add-on listed twice. For the record, I always install add-on for all users.
Just a guess: maybe there's a relation with the famous "install as Admin" issue?

I would love to fix it, but I have never reproduced the issue and also haven't found a reason for it.

If would be very helpful if you could find exact steps how to reproduce the issue.
Something like:
1. Download this addon ....
2. Install it as current user....
3. ......

I still have this problem of extensions displayed twice in 4.0.3.1466.
One for "All users" and one for "Current user".

I think the listed twice problem is linked with the disappearing add ins.
http://www.mediamonkey.com/forum/viewtopic.php?f=6&t=63605
It effected all add-ins including add-in that were installed and working ok - just not being listed.
If I re-installed the add in it got listed twice.
The same with new add ins.
It appeared for me on a 1462 to 1463 debug non-portable upgrade.
I cannot reproduce now because I am now on a 1464 portable install
Running MM on 32 bit Vista as administrator.

I have to correct myself again, the Chinese was twice there because there are two versions of Chinese translation (simplified and traditional).
So I still cannot reproduce the issue.

I have to correct myself, just downloaded Chinese translation, unchecked
'[ ] Install for current user only' checkbox and the Chinese is twice in the list.

I cannot reproduce, are there any steps to reproduce?
Is it specific to a kind of addon, e.g. languages only?
MediaMonkey shouldn't allow you to install same addon twice.

I use standard (non-portable) version.

Can you please move it together?

Already reported here: http://www.mediamonkey.com/forum/viewtopic.php?f=6&t=63676&hilit=extensions, but not yet reproducible.

Under Tools -> Extensions all the extensions appears twice (identical, not different versions).

If I delete one entry (ie 'German Translation') and open Tools -> Extensions again, BOTH entries are deleted.

Yes, they do indeed appear twice in the Extensions list, but one is current user and the other is all users.
Either way, it will get messy with it like that.
