Setting up the server used for running installers involves temporarily disabling User Account Control (UAC), ensuring that the application pools are started, and ensuring that Windows PowerShell scripts can be run by the installers.
Note: The Nintex Forms installer must be run on a front end server.
Note: The installers need to be run on a single server in the farm only. If you plan to use Nintex Live, choose a server that hosts SharePoint Central Administration. Doing so allows you to avoid extra steps when connecting and enabling Nintex Live.
To temporarily disable User Account Control (UAC)
On the server that you plan to use for running the installers, from Control Panel, select Change User Account Control settings.
Note the original settings for User Account Control (UAC).
You'll need the original settings to revert after installation.
Disable User Account Control (UAC).
For instructions on disabling UAC, see the following URL: http://windows.microsoft.com/en-us/windows/turn-user-account-control-on-off#1TC=windows-7
To ensure that the application pools are started
On a server that can access the application pools, open IIS Manager.
For instructions, see http://msdn.microsoft.com/en-us/library/vstudio/bb763170(v=vs.100).aspx.
Expand the server and then click Application Pools.
Status is indicated for each application server, such as SharePoint - 80 and SharePoint Central Administration v4.
To ensure that Windows PowerShell scripts can be run by the installers
On the server that you plan to use for running the installers, determine if Windows PowerShell script execution is set by group policy:
Open the Local Group Policy Editor (gpedit.msc); for instructions, see http://technet.microsoft.com/en-us/library/cc731745.aspx.
Navigate to Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Windows PowerShell.
Click Turn on Script Execution.
In the Turn on Script Execution dialog box, determine if the Enabled setting is grayed out (unavailable).
Unavailability of this setting indicates that group policy is used.
Navigate to Local Computer Policy > User Configuration > Administrative Templates > Windows Components > Windows PowerShell.
Click Turn on Script Execution.
In the Turn on Script Execution dialog box, determine if the Enabled setting is grayed out (unavailable).
Unavailability of this setting indicates that group policy is used.
If group policy is used for script execution, ask your network administrator to do one of the following:
Allow script execution policy to be set individually (turn off group policy for that server).
Set the policy to Unrestricted for the user and server to be used for installation.
When the ability to execute Windows PowerShell scripts is available, you can continue on to the next step in setting up the topology for installation.
