Side by Side configuration thing, how do i fix it?

[Oliver]

So when i press play a massage comes up saying that my side by side configuration is wrong (or something like that) I dont even know what that is, please help me.

This occurs when either the Steam Client software and/or the account that ran the install of FSX did NOT have administrative permissions to the WPFS (Windows Protected File System) during the install and could not install the C++ redistributable. Or if someone deletes them from Add/Remove Programs.

Fortunately the Steam/Dovetail team anticipated this. To fix this Steam stores a copy of the C++ version FSX needs right on our hard drives when FSX is installed. Both x86 and 64bit versions.

They can be found in following path under your Steam installation which by default is:

C:\ProgramFiles(x86)\Steam\steamapps\common\Steamworks Shared\_CommonRedist\vcredist\2005

(note a SPACE between the word Steamworks and Shared= "Steamworks Shared" and note the underscore before CommonRedist in the path)

vcredist_x86.exe
vcredist_x64.exe

install both.

You must run these with an account that has "administrator" access and if you get this right the "side by side" error will go away. This all is due to the fact that WPFS (Window Protected File System) did NOT exist when FSX was developed, and it needs access to folders now deemed administrator only access.
