v9 webinterface iis error 500.19

Hi,

I am trying to get commitcrm webinterface to work on https://domain.com
I would like the login page to appear when said users browse to https://domain.com and not have to put in /CommitCRM/

If i go into the application that was created and content view and browse the commitcrm.dll it opens fine with the long URL, but if i go to domain.com it fails with error below.

when trying to open the webinterface from IIS i get the following error

HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.

Detailed Error Information:
Module DefaultDocumentModule
Notification ExecuteRequestHandler
Handler StaticFile
Error Code 0x800700b7
Config Error Cannot add duplicate collection entry of type 'add' with unique key attribute 'value' set to 'CommitCRM.dll'
Config File \\?\C:\CommitCRM\WebInterface\web.config
Requested URL https://localhost:443/CommitCRM
Physical Path C:\CommitCRM\WebInterface
Logon Method Anonymous
Logon User Anonymous

Config Source:
5: <files>
6: <add value="CommitCRM.dll" />
7: </files>

Also i have run the command below per the installation troubleshooting notes:
%windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/httpCompression /-[name='xpress']

The easiest way would be to create a redirect page in html or php to redirect users to the long url.

Thank you for posting this. The URL should contain the full path, for example: https://yourdomain.com/RangerMSP/RangerMSP.dll
You can use a redirect, as suggested by @nattivillin, or set RangerMSP.dll as the default page for the web site you configure in IIS.

As for the error 500.19 you may try the solution described here.

Hope this helps.
