Seriously ?? .... Im running migration tool which allows Pepar3d to run like FSX for Compatibility. There's a old topic on this but this information is not simple.  http://forum.simflight.com/topic/71840-registration-issue-with-migration-tool/  This program makes a copy of Prepar3d.exe and renames it Fsx.exe and changes the version information...  This allows things like scenery and aircraft to install and function. Your program loads fine within both exe's However the registration information is not activated/found in Fsx.exe but it is fine in Prepar3d.exe. The Loader.dll works fine and can be found within "addons" tab.           INSTALLATION FOR FSX: 
SetupPath="C:\Program Files (x86)\Lockheed Martin\Prepar3D v2\"
Checking version of the FSX EXE:
... Version 10.0.61637.0  (Need at least 10.0.60905.0)
Checking compatibility with installed SimConnect:
    Found SimConnect build 60905 (Original)
    Found SimConnect build 61242 (SP1 May07)
    Found SimConnect build 61259 (Acc/SP2 Oct07)
Checking if there's already a version of FSUIPC4 installed in:
       C:\Program Files (x86)\Lockheed Martin\Prepar3D v2\Modules\FSUIPC4.DLL
... No previous valid version found.
FSX Modules folder created okay!
Okay -- installed FSUIPC4 into "C:\Program Files (x86)\Lockheed Martin\Prepar3D v2\Modules\FSUIPC4.DLL"
Looking for the current user's Application Data path: 
... found as "C:\Users\ZoneDT\AppData\Roaming"
Now finding \Microsoft\FSX\FSX.CFG for all users, including this one
Looking in "C:\Users\All Users\AppData\Roaming"
 ... No FSX.CFG there
Looking in "C:\Users\Default\AppData\Roaming"
 ... No FSX.CFG there
Looking in "C:\Users\Default User\AppData\Roaming"
 ... No FSX.CFG there
Looking in "C:\Users\Public\AppData\Roaming"
 ... No FSX.CFG there
Looking in "C:\Users\ZoneDT\AppData\Roaming"

Now checking DLL.XML ...
... There is a previous DLL.XML, checking for FSUIPC4 section.
... FSUIPC4 section already exists but will be replaced.
     (for FSUIPC4, without Loader)
... FSUIPC4 section of DLL.XML written okay
Now checking for a SimConnect.XML file ...
... No SimConnect.XML file found. This is okay.
"Modules\FSUIPC Documents" folder created okay!
Now installing additional files into the "Modules\FSUIPC Documents" folder:
   Installed "FSUIPC4 User Guide.pdf" okay
   Installed "FSUIPC4 for Advanced Users.pdf" okay
   Installed "FSUIPC4 History.pdf" okay
   Installed "List of FSX and P3D controls.pdf" okay
   Installed "FSUIPC Lua Library.pdf" okay
   Installed "FSUIPC Lua Plug-Ins.pdf" okay

   Installed "ASN WX Radar facilities in FSUIPC4.pdf" okay
   Installed "Offset Mapping for PMDG 737NGX.pdf" okay
   Installed "FSUIPC4 Offsets Status.pdf" okay
   Installed "Profiles in Separate Files.pdf" okay     Loads in both exe's like i said. Appears in addons.     Prepar3d.exe loads fine with Registration information.       Load the game with the edited Prepar3d.exe aka "Fsx.exe" and the registration information will not appear/load.   Let me know what i should do, thanks pete.
