Installing Sharepoint 2010 on Windows 7 x64

The process for of installing sharepoint 2010 on windows 7 is rather simple unless you run into some issues as I did.


  1. Download or have ready sharepoint 2010.
    • On my development environment I just run sharepoint 2010 foundation server which can be download here.
  2. Then you want to follow the instructions found at the MSDN site
  3. This all went pretty smoothly for me until I run the psconfig (Sharepoint Configuration Wizard) where I hit an error

An exception of type System.Security.Cryptography.CryptographicException was thrown. Additional exception information: The data is invalid.

Turns out that I needed to give my “Network Service” account full permissions to the 14 hive found at C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14.
However this didn’t resolve the issue straight away and that’s when i found Bill Baer’s comment on the TechNet forum which says the following

Right click on the folder (‘%CommonProgramFiles%\Microsoft Shared\Web Server Extensions\14), select the Security tab, click Edit, click Add, as the user type “Network Service”, then click OK and apply. Grant the user Full Control. This will work on its own if you do it before running PSConfig.
If you’ve already hit the error, you may have to run psconfig –cmd configdb disconnect then delete the old configuration database from your SQL instance, then add the ACL and re run PSConfigUI.

After I had disconnected the database and manually deleted the config databases through Management Studio I was able to re-run the psconfig successfully.
