k-lite-mega-codec-3-pack and videowalpaper (PUSH Entertainment) plant Windows 7

Good morning.
I wanted to install the "k-lite-mega-codec-3-pack_10 0_fr_35535".
I wanted to start videowalpaper and he struggled to get started. he even managed to crash "explorer.exe" (Windows. ..). in fact, when the PAK is installed and when you start videowalpaper the "LAV" program PAK, starts at the same time and plant "explorer.exe."
I think in videowalpaper, a routine must call the LAV program when the program is launched.
I will also try to transmit this bug report, also designers of "k-lite-mega-codec-3-pack_10 0_fr_35535".
I can not use these two programs simultaneously.
thank you.

this is a copy of the message I sent to PUSH Entertainment.
I am French and I use google translate. I never learned English at school.
as I work . if you have an answer or a question , use philumax@wanadoo.fr .
thank you and more. 

Do you also get a crash if you play the same video with MPC-HC player?

Good morning.
videowallpaper is a "dreamscene". I do not really have a choice.

Solution 1:
LAV Video decoder > Formats > disable VC1

Solution 2:
Codec Tweak Tool > Preferred Splitters > Select LAV for WMV

If you have 64-bit version of Windows, then you need to make changes for 64-bit version of LAV.

Good morning.
is what I should uninstall the software before or is it that I can make these changes directly.
as was LAV that was the problem, I replaced wherever I found it, by FFDDSHOW.
yet, no conflict.
thank you.

You can make the changes directly. Configuration can be accessed through shortcuts in the Windows Start menu.

thank you very much.
I glue it as soon as possible.

Did you get any response from Push Entertainment? The crash seems to happen because of a bug in their software.

no!
it is a software unpretentious. but I do not despair of an answer.
