DRM Web Client 500.19 issue on windows 2008(x64)  ERROR

Hi,

I installed DRM version 11.1.2 on windows server 2008(x64), according to the documents, I pre-installed .Net 3.5.1 and modified the applicationHost.conf file.

I found this in epm_install_troubleshooting

Web Client Access Failure
Issue: After installing Data Relationship Management on Windows 2008 64-bit platform, you
get this error message when attempting to access the Web client:
HTTP Error 500.19 - Internal Server Error The requested page cannot be
accessed because the related configuration data for the page is invalid.

Solution: In the IIS configuration file (C:/Windows/System32/inetsrv/config/
applicationHost.config), replace the two occurrences of Deny in the following section with
Allow:
<configuration>
<configSections>
<sectionGroup name="system.webServer">
<section name="handlers" overrideModeDefault="Deny" />
<name="modules" allowDefinition="MachineToApplication"
overrideModeDefault="Deny" />

However when I access the web client I got the 500.19 error, can't find C:\inetpub\wwwroot\drm-web-client\web.config, the web.config file do not exist.

Config File \\?\C:\inetpub\wwwroot\drm-web-client\web.config
