1. Obtain an account with sufficient permissions. Ensure that the user account performing the installation and deployment (Windows user as well as user logged into Central Administration) is the Farm Installation account and that it is a Local Administrator on the server used for installation.
2. If your installed version is 2.4.1.0 or previous, uninstall the current version of Nintex Workflow 2010 using Uninstall or change a program on the server on which it was installed. (This action does not affect the product's functionality).
   Warning: Do not retract the Nintex Workflow 2010 solutions via SharePoint administration. Retracting the solutions is not required and retraction would disrupt users currently using the product.
   If your installed version is 2.4.2.0 or later, skip this step.
3. Run the new installer (.exe file) for Nintex Workflow 2010.
   1. On the Confirm Installation page, at the prompt "Do you want to add the solution to SharePoint now?," select Yes. The installer will attempt to upgrade the solution in SharePoint.
   2. On the page that lists the Nintex Live installation option, select Install Nintex Live. This option installs the Nintex Live Framework, which is required to enable the Nintex Workflow - Nintex Live Catalog feature.
      After installation the Solution Management page appears.
4. Refresh the Solution Management page until the installed Nintex solutions are listed as Deployed.
   
   The Nintex solutions installed by the Nintex Workflow 2010 installer are listed in the installation guide. See Installing Nintex Workflow 2010 and Nintex Forms 2010.
   
   Note: If the page lists the solution as Deploying with a timestamp, refresh the page until the solution is listed as Deployed. If the page says Service Unavailable, then IIS is restarting. Refresh the page until it displays.
   
   Note: If you receive an error when attempting to access a Nintex Workflow administration page, ensure that nintexworkflow2010core.wsp is deployed globally and that nintexworkflow2010.wsp is deployed to the Central Administration web application. To view deployment status, on the Central Administration Home page, click System Settings, then click Manage farm solutions in the Farm Management section. For instructions on deploying solutions, see Installing Nintex Workflow 2010 and Nintex Forms 2010. (Note: The deployment option “All content web applications” does not include the web application.) No IISRESET is required for deployment to the Central Administration web application.
   
   If any errors appear for installed solutions, then the solution package upgrade has failed. To resolve the error, click the solution and click Deploy Solution. In most cases, the solution is then deployed. If not, reset IIS (Start->Run->iisreset) before clicking Deploy Solution again. Resetting IIS resolves this issue as it releases all locks on the application files. After deploying manually, reset IIS on each front end server.
5. If the release notes indicate that a database update is required, then do the following.
   1. In SharePoint Central Administration, in the Quick Launch menu, click Nintex Workflow Management.
   2. Click Database Setup.
      If a database update is available, it will be indicated in green with an option to “Update now” .
   3. Click Update now.
      
      Note: If you receive an error when attempting to access a Nintex Workflow administration page, ensure that the nintexworkflow2010.wsp solution package is deployed to the Central Administration web application. To do so, go to System Settings > Manage Solutions in this farm and then click nintexworkflow2010.wsp. Click the Deploy Solution link and select the Central Administration web application from the drop-down. (The deployment option “All content web applications” does not include the web application.) No IISRESET is required for deployment to the Central Administration web application.
6. Enable Nintex Live.
   1. In SharePoint Central Administration, in the Quick Launch menu, click Nintex Workflow Management and then click Live settings.
   2. In the Enable Nintex Live for Nintex Workflow section, click Enable and then click OK.
7. Reset IIS (Start->Run->iisreset) on all SharePoint farm servers and then restart the SharePoint 2010 Timer:
   1. Open the Services Microsoft Management Console (MMC) snap-in.
      For instructions on accessing the Services Microsoft Management Console (MMC) snap-in, see the Microsoft article Services.
   2. Right-click the service and select Restart.

Note: If Nintex Workflow for Project Server 2010 is installed in the same environment, restart the "Microsoft Project Server Queue Service 2010" service and do a final IISreset on each server.

After any update, we recommend clearing temporary files stored by the browser so that cached JavaScript files are not used and no previous errors continue occurring.
