Hello!
It's good everything works.
Here is the procedure I used:
1) download all products New Installer
2) uninstall all FSDreamteam products
3) Empty the directories of FSDreamTeam
4) Check the registry entries:
RootKey: HKEY_LOCAL_MACHINE
Key: \ Software \ Microsoft Games \ Flight Simulator \ 10.0
Subkey: SetupPath
and
RootKey: HKEY_CURRENT_USER
Key: \ Software \ Microsoft \ Microsoft Games \ Flight Simulator \ 10.0
SubKey: AppPath
if they are present erase them.
5) check the presence of FSX files in c: \ program files; C: \ programdata, c: \ users \ Username \ appdata \ Roaming and \ local
Delete these FSX related files
6) Delete after saving the registry entry
HKEY_LOCAL_MACHINE \ Software \ FSdreamTeam
7) Reinstall the FSdreamteam products and activate them with the Addon manager in P3DV4.
Thanks to everyone involved in this thread and Happy flights!
