您可能会在为Windows版Plesk 11运行AutoInstaller时遇到此错误：

Unable to install the "plesk-11.0.9.noarch"; package. The following could cause the installation failure: 1) plesk-11.0.9.noarch: No suitable solutions were found for the "IIS"; dependency. 2) The dependency for "IIS"; required by the "plesk-11.0.9.noarch"; package could not be resolved.

这意味着您尚未在服务器上安装IIS角色。
要安装依赖项，请按照下列步骤操作：

Open the Server Manager (Start > Administrative Tools > Server Manager) ;
 Click on Roles and then Add Roles ;
 Check the boxes for "Application Server"; and "Web Server (IIS)"; .

然后运行Windows Update，重新启动服务器，然后再次通过Plesk AutoInstaller重新启动。
