Can’t install Nintex Workflow 2010?

Posted by Patrick on August 9, 2010

After a long week at work, I finally got a chance to spend some time on my SharePoint 2010 VM yesterday. I wanted to install Nintex Workflow 2010 to have a bit more of a play with it. During the install I encountered an error that I thought is definitely worth mentioning it

First of all, and that is apparently a quite popular question I get, you need SharePoint 2010 to use Nintex Workflow 2010. Nintex Workflow 2010 does not run on MOSS and Nintex Workflow 2007 does not run on SharePoint 2010.

However, if you are a Nintex customer and have software assurance, you can upgrade for no extra fee. Also you will be able to run all your Nintex Workflow 2007 workflows in Nintex Workflow 2010.

If you try to install Nintex Workflow, first of all make sure that the account you use for the install is part of the farm admin group and an admin on the server.

Second, and this is where I spent a lot of time searching for the underlying issue, make sure that (at least for the installation) you have turned off UAC (User Account Control) or set it to the very minimum.

Otherwise you will be getting the following error when the installation tries to deploy the solution packages:

The Zone of the assembly that failed was:  MyComputer

Don’t know how to change the UAC settings? Follow these steps:

1. Click on Start, and then Control Panel
2. In Control Panel, click User Accounts
3. In the User Accounts window, click User Accounts
4. In the User Accounts tasks window, turn the User Account Control to the very minimum
5. Restart to apply the changes
