ASP.NET 5 Failed to initialize runtime on IIS - iis

Question

I got below log error when I publish my ASP.NET 5 RC1 project to the IIS server.
Failed to initialize runtime 0x
IIS 7.5, installed 64 bit HTTP Platform Handler and followed below instructions
docs.asp.net/en/latest/publishing/iis.html
I have the project working well locally with VS2015 and IIS Express.
Any idea about this error?
Updated approot folder structure:
Runtimes folder:
Web.config in wwwroot(auto-generated):
<configuration>
<system.webServer>
<handlers>
<add name="httpplatformhandler" path="*" verb="*"
modules="httpPlatformHandler" resourceType="Unspecified" />
</handlers>
<httpPlatform processPath="..\approot\web.cmd"
arguments=""
stdoutLogEnabled="false"
stdoutLogFile="..\logs\stdout.log"
startupTimeLimit="3600"
forwardWindowsAuthToken="true"></httpPlatform>
</system.webServer>
</configuration>
web.cmd in approot(auto-generated):
#echo off
SET DNX_FOLDER=dnx-clr-win-x64.1.0.0-rc1-update1
SET "LOCAL_DNX=%~dp0runtimes\%DNX_FOLDER%\bin\dnx.exe"
IF EXIST %LOCAL_DNX% (
SET "DNX_PATH=%LOCAL_DNX%"
)
for %%a in (%DNX_HOME%) do (
IF EXIST %%a\runtimes\%DNX_FOLDER%\bin\dnx.exe (
SET "HOME_DNX=%%a\runtimes\%DNX_FOLDER%\bin\dnx.exe"
goto :continue
)
)
:continue
IF "%HOME_DNX%" NEQ "" (
SET "DNX_PATH=%HOME_DNX%"
)
IF "%DNX_PATH%" == "" (
SET "DNX_PATH=dnx.exe"
)
#"%DNX_PATH%" --project "%~dp0src\Pms.Client.Web" --configuration Debug web %*
Tried to use WinDbg the dnx.exe on server and got below error code. Hope someone is able to interpret for me. Thanks!

Figured out this issue. The answer is simple enough, but the story is long.
I just installed .NET Framework 4.5.1 on server and the error has gone.
Then I got another well-known issue about
"
you must add reference assembly to System.Runtime
"
Tried every way I found in this site and gave up eventually. The magic came out when I checked option to build binaries when publishing:

Just post this workaround for peoples that may encounter similar situation. Still I am not very clear about underlying things.
