SharePoint 2010 – Word Web App cannot open this document error

We recently had an error in one of our SharePoint 2010 farms when a user opened a Word document from a SharePoint library they would see this pop up error


 The ULS logs showed:  ….. Failed to create the sandboxed process   …..

 Running the following PowerShell command on one of the SharePoint servers and performing an iisreset on all the SP servers appears to have fixed the issue.

$e = Get-SPServiceApplication | where {$_.TypeName.Equals(“Word Viewing Service Application”)}

$e.WordServerIsSandboxed = $false
