When i was downloading FSX for the first time my pc shut down, after that i downloaded it again, but instead of it tuening on when i clicked play, it greeted me with a pop up message that my game is wrongly configured and it says that its error 0x36B1. Can anyone help?

1. The error code 0x36B1 is not unique or specific to FSX-SE, but instead is a "steam" error. Other steam games, such as Warhammer, reports the same error.

2. It seems to be a problem with one of the "redistributable" dependencies, specifically 2005. Not all redistributables are "cumulative", meaning new updated redistributables do NOT ALWAYS incorporate the "previous" version.
(Even though you may have the latest redistributable installed, you still (also) need 2005. Hence the "side by side" message.)

3. I cannot find any "quick" solutions to the fix the problem. But I would suggest the following:
Follow the path as in the red oval. Your installation path may differ, but main thing is to get to "steamapps > common>FSX >_CommonRedist > vcredist > 2005.


4. Then, run those two exe's, so as to do a reinstall, with the hope that a "reinstall" may do the trick. (Otherwise download 2005 from MS website)
