FSX:SE Blackbox Preflight Manager won't start

[theLox 0]

Hello,

I've got a problem with the blackbox preflight manager. Every time I try to start it, I get this message:

SimConnect Client v10.0.61259.0 Not Found

The Application Will Now Quit.

What can I do about this?

Thanks for your help!

Most likely one of the required simconnect versions is not installed or got corrupted for some reason.
Don't remember exactly where the installers are located.. In FSX boxed I believe they are on disk 1, on Steam, again I believe they are in the root sim folder / redist..
v61259 is the acceleration version.

Run all the *.msi installers, as administrator, and you should be good to go. 
No harm, likely better, to install all versions available to you.

Here is a nice write up regarding simconnect and it's installations.

I have a problem with the .msi installers now. Everytime during the install process this message appears:

An error occured during the installation of the assembly

"Microsoft.VC80.CRT,type="win32",version="8.0.50727.42=,publicKeyToken="1fc8b3b9a1e18e3b",processorArchitecture="x86"".

(I don't know if that was the exact translation because im austrian, but I think you know what I mean.)

Thanks for your help!
