I have the old original Briefing Time B-25J Mitchell CD for FS2002.

 

I have downloaded and installed the update for FS2004 and the bird flies beautifully in FS2004.

 

I have also downloaded the 2004 to FSX update, and installed it. The aircraft and panel display just fine in FSX, but every time I click on a toggle/simicon shortcut or try to bring up a secondary panel from the views>Instrument Panel options, FSX closes down. I thought I had this going at one time, but after I upgraded to Windows 7, I never tried reinstalling the B25J into FSX until now. Any ideas as to what I am doing wrong, or Is this old  version not compatible, even by installing the updates? I had no problem with the R4D-6 flying in FSX (It is from the old original early version CD with updates as well).

 

Respectfully::

Edit: Told a fib but did not know it. In FSX I just selected one of the RFD-6 / DC3 birds and had the same problem. It has been a while since I selected and flew these, but they were installed and flew fine some time ago in FSX.

You may have to bite the bullet and spring for the latest versions of both planes to get them working properly in FSX/Win7.  Too many things have changed since FS2002 for me to even hazard a guess at what the issue may be.
