A wonderful gift from Roy Chaffin at RCS panels!...HE SAYS
"I am delighted to announce and release, a new version of the RCS B-25J.
Over the years we have made quite a number of changes, improvements, and added liveries to the basic B-25J package, so it is now becoming very complicated to ensure you have the latest of everything. Therefore, rather that release yet another add-on to give you more liveries and stuff, I have decided to release a complete new package that includes the basic aircraft and everything in one 'EXE' file. This is version 2.75.
This wonderful new version contains more magnificent liveries by our 'Master of textures' Steve Wayne.
You do not need to 'Uninstall' the previous version, just install the new 'EXE' over the top of the old one.
So far I have put together the 32-bit and 64-bit FSX versions. There is no difference in the content, it just installs in the correct location.
