I recently ran the SharePoint 2010 installer, still in Beta, and had no issues during the installation. My system was configured as a Windows Server 2008 R2 64-bit with a separate Domain Controller. This was a “clean” server so nothing else was installed. Next I ran the SharePoint 2010 installer and decided to start by using a StandAlone install, I figured that if this worked then I could proceed to a Farm Installation.
Before I go any further let me commend Microsoft on improving the SharePoint installation process. I really appreciate the fact that they have now configured the installer to handle installing all pre-requisites instead of just halting and requiring the user to perform these steps.
After the installation completed I ran the SharePoint Configuration wizard, but when I got to the last step I suddenly got an error:
“Unrecognized attribute ‘allowInsecureTransport’. Note that attribute names are case-sensitive. (C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\WebClients\Profile\client.config line 56) —> System.Configuration.ConfigurationErrorsException: Unrecognized attribute ‘allowInsecureTransport’. Note that attribute names are case-sensitive. (C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\WebClients\Profile\client.config line 56)”
I checked the file (client.config) and sure enough the line appears as described in he error message above. Not sure if the installation was now broken or not I attempted to access Central Admin, SUCCESS. Next I looked at the SharePoint Web Applications and noticed a Team Site on port 80 had been created. I checked this site to see if it would work, SUCCESS!
Finally I decided to push my luck and see if a Visual Studio 2010 Web Part could be created and deployed to the new SharePoint 2010 environment. SUCCESS!
To date I have not seen any issues resulting from the error message, I am still testing and will update this posting if I run into any issues.
The Microsoft Team has a resolution for the issue described above.
