hagar,
Thanks for your proposal.
Here the file (complete file with model , sounds, etc) :
http://library.avsim.net/esearch.php?Ca ... ID=&Page=9or you can use download id = 120026 on avsim.
On my WIN XP config (XP+FSX+SP1+SP2) I have no problem at all : plane shows up in de FSX menu and id flyable. Although the panel and sounds cfg are pointed to default directories.
On my WIN VISTA config (VISTA+FSX+SP1+SP2) I used exactly the same 'install procedure' (cfr unzipping in folder on desktop, copying folder to the correct simobject/airplaine folder), but the plane does not show up. I made sure thumbnail.jpg is there ..
As workaround I replaced the sound and panel folders with sound and panel folder I used from another B737-300 and with that change everything looks fine in FSX too.
I DON'T UNDERSTAND WHY I HAVE TO ADAPT SOUND and/or PANEL FOLDERS in VISTA TO MAKE IT WORK as in WINXP all IS FINE FROM THE FIRST TIME.
Interesting consideration ...FSX under XP and VISTA is working differently in my opinion ...
Thanks again to let me know your test results. have a nice time.
