Relatude is a relatively standard ASP.NET application, so installation is fairly straight forward. Below you can see information on how to configure both IIS.
General IIS configuration
Relatude CMS & E-commerce needs full access to the file system within the website root folder. This means giving the ASP.Net user and the App_Pool Process identity user (normally NetworkService) full access in the NTFS file system. On some systems the “Network Service” system user must be given full access to the .Net temp folder as well:
By default IIS has turned on App recycling after a period of inactivity. When Relatude is shut down, the cache is cleared. When a request is sent to the website after it has been recycled, the application must start up. This is a fairly heavy process, so the response will be much slower than a normal page request. We therefor recommend that you turn off App Pool recycling as much as possible to give your visitors a good experience:

With SQL Express with IIS7 you might encounter the following error: "Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed." This error can often be fixed by disabling Asp.Net Impersonation under the Authentication section in IIS manager for your site. Please make sure disabling impersonation is a valid option for your scenario.
