Pop up windows warnings FS2004

[jfg123]

Sim. People,

What do I do with the pop up warings of FSSim.dll, FSuipc.dill and Soarec.dill, this pop up at the begining of loading FS9?
Do I say Ok to load software even though FS9 warns me they may be incompatible or do I say No?

Can these files be put into FS9 program so they will not pop up?

Thanks for any helps you can give JFG 123

 You might want to check and make sure you are loading the correct version for FS2004. The only other way to avoid this is to put a statement in fs9.cfg as follows
          Old files
fsuipc.dll=1
fssound.dll=1
and so on for each old dll you are using.
  BEWARE that to make sure this is the right version otherwise it might cause unwanted results.

what this does is tell fs9 that you are using dll files from an earlier version of MSFS .
the 1 means true 0 = false
I think I got the format right the word OLD FILES might need parenthise around it.
 At work so I can not check

Thanks Garymuska,
Your technical answer may help some but it is too dificult for me to do. I could never even find, after many reads of this sim. forum, the FS9 cfg. And so can't begin to add any lines in its program. Now I just want to know to say yes or now to the pop up widows of those files that say they may be harmful to the game?
Thanks for Your helps again JFG123

The fs9.cfg file is hidden, that is why you cant find it. You need to go to the control panel and set it to show all hidden files and folders....

The correct entry in the FS9.cfg is this:

[OldModules]
fsuipc.dll=1                
fssound.dll=1

You might also try adding the other ones you get an error message on to see if it eliminates your warnings on those. It would be like this:

[OldModules]
fsuipc.dll=1
fssound.dll=1
fssim.dll=1
soarec.dll=1

fssim and soarec I haven't heard of. You must have gotten them with a progam or acft. you downloaded for use with FS9.

Should work though as long as you add them correctly.
