Unable to Deploy Workflow

Problem: When generating the Mobile Workflow package, you get an error that the Mobile Workflow package cannot be deployed similar to this:

============================================================
Deployment to Unwired Server
============================================================
Deploying the workflow
Unable to deploy workflow: System.Web.Services.Protocols.SoapException: Could not find a 
part of the path 'C:\Sybase\UnwiredPlatform\Servers\MessagingServer\Data\Mobile Workflow\117_1'.
at Admin.ReplaceWorkflow(Byte[] baZippedPackage)

Explanation: Some software, such as Microsoft Security Essentials, locks the temp folder, or files in the temp folder when they are written by the Workflow installation routine, thus preventing the Directory.Move from succeeding.

Solution: Disable Microsoft Security Essentials.
