Windows – Error code 0x80070643 when installing IIS7 role services

asp.netiis-7windowswindows-server-2008-r2

I am attempting to install IIS7 "Application DevelopmentASP" role via the Server Manager's
"Add Role Services" wizard. Some of the roles include ASP.Net, .Net Extensibility, ASP, ISAPI Extensions, etc. I have now successfully installed other roles under the Application Development heading. ASP is the only issue When attempting to install these I receive the following error for each service that I attempt to install: 

Attempt to install <the service name> failed with error code 0x80070643.  Fatal error during installation.

I am able to successfully add Role Services that do not belong "Application Development". For example, I was able to install Health and Diagnostics -> Tracing, Custom Logging, and ODBC Logging without an issue.

I have tried the following:

-The 2 Methods here: http://support.microsoft.com/kb/976982  
    -Microsoft Fix It 50123 *EDIT Added this*
    -Repair .Net Framework 4.0
-Removed WAS (Windows Process Activation Service) from Features, Restarted server, and then attempted to install the role services.

I the following System:

Windows Server 2008 R2 Standard SP1 64 bit

Edit 3/7/13

I have now successfully been able to add roles under "Application Development", but was not able to do these all at once because I still experience the issue with the "ASP" role. The issue with this single role was stopping me from installing any of the others at the same time. I have now individually installed those, but still want to install ASP.

I would try:

  • C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -ua
  • restart.
  • add roles/features.
  • restart.
  • aspnet_regiis.exe -i

If you need other/multiple versions of ASP.NET, you would need to run the appropriate aspnet_regiis.exe -i for that version/platform (x86/x64).
