Media Encoder CC2014.2 crash on windows when trying to export when quicktime is installed

Question

Hi,
I'm trying to export .mov files (created on random Mac computers in very hi-res) to reduce file size, and have the same output format. (possibly 1080p H.264-> .mp4)
I installed Media Encoder cc2014.2 on my pc (win7, 64bits, french).
When I first tested, Only the audio was being exported. But I soon realized I didn't had the proper codec installed on my PC.
(I wasn't able to play the original video file, only the audio was playing).
So, like a good boy I installed Apple Quicktime (7.76.80.95)
With quicktime on my PC I was able to play the original video file. (with quicktime player)
So I opened Media Encoder again, and on the preview this time I can see the video with the sound. But as soon as I start the coding (the little green arrow) Adobe Media Encoder crash.
I have tried multiple output format, it always crash right when I start exporting the file.
I uninstalled Quicktime, and media encoder is working again ... but my original files (.mov) can't be exported with video, only the sound.
I have tried a third party codec (K-Lite), I can see the video+sound on my pc, but Media Encoder is still blind, no video, only the sound.
Is there a way to add codec to Media encoder without having to install Quicktime?
Or a way to make Media Encoder work on my PC when Quicktime is installed?
btw I'm sorry if my text is a bit confusing, I'm french speaking
Thank's in advance!

The Error is back!!!
Yesterday it worked today it crashes when I export from premiere via media encoder. I tried it with all the things you told me:
1. Bars+Tone => export => crash
2. Video Project with 2 short h264-files => export => crash
3. Software only renderer => crash
These are the two logs that I found:
