"HTTP 500 Internal Server Error" after installing Sharepoint 2010 on Win 7

After completing the configuration wizard, you get a HTTP 500 error instead of the Sharepoint site welcome page.

Check the required features in the IIS section of the Windows Features dialog box (which you can access through the Programs section in Control Panel)and make sure that ASP .Net is checked.

I hope this helps.

"IIS is not installed" error is displayed when trying to install Sharepoint 2010 on Win 7 64bit

I was able to get through the initial installation of Sharepoint 2010 Beta (14.0.4536.1000) on my Win 7 64 bit system. The next step was to run the configuration wizard which I did. It warned me that some services need to be started which includes IIS (7.x). I eventually got an error stating that IIS was not installed on my system.

I was able to resolved this error by running the following statements in the command prompt then running the Sharepoint 2010 setup.exe again after. This installs all IIS component using the command line prompt.

start /w pkgmgr /iu:IIS-WebServerRole;IIS-WebServer;IIS-CommonHttpFeatures;
start /w pkgmgr /iu:IIS-StaticContent;IIS-DefaultDocument;IIS-DirectoryBrowsing;IIS-HttpErrors;
start /w pkgmgr /iu:IIS-ApplicationDevelopment;IIS-ASPNET;IIS-NetFxExtensibility;

start /w pkgmgr /iu:IIS-Security;IIS-BasicAuthentication;IIS-WindowsAuthentication;IIS-DigestAuthentication;
start /w pkgmgr /iu:IIS-RequestFiltering;IIS-Performance;IIS-HttpCompressionStatic;IIS-HttpCompressionDynamic;

start /w pkgmgr /iu:WAS-NetFxEnvironment;WAS-ConfigurationAPI;WCF-HTTP-Activation;
start /w pkgmgr /iu:WCF-NonHTTP-Activation

I hope this helps.
