In order to make the webpart work, please perform the following steps:

1. Add access rights for the users IIS_IUSRS and NETWORKSERVICE to some DCOM-Components, which are:

-WIA Device Manager
-WIA Extension Host for 64 bit extensions

If you are not able to set any access permissions for this DCOM-Components - you have to take ownership to them via the registry, if you don't know how to do this, watch

2. Install from Package "WithoutSetup"

2.1 Install the Farm Solution

Open your "SharePoint 2010 Management Shell" and type the following command into the shell:

Add-SPSolution FULLPATHTOWSP\DeploymentProject.wsp

Please replace FULLPATHTOWSP always with the full-path to the DeploymentProject.wsp file

Then we need to deploy the solution to the farm:

Install-SPSolution -Identity DeploymentProject.wsp -GACDeployment


3. Install the User-Solution from "SharePoint 2010 Management Shell"

First we need to upload the user-solution to the local sharepoint-site:

Add-SPUserSolution -LiteralPath FULLPATHTOWSP\embDocumentInhalator.wsp -Site http://URLTOYOURSITE

Please replace the FULLPATHTOWSP with the full path to your embDocumentInhalator.wsp file and URLTOYOURSITE with
the url to your SharePoint site in wich you want the user-solution to install.

Second step is to deploy the user-solution to the site:

Install-SPUserSolution -Identity embDocumentInhalator.wsp -Site http://URLTOYOURSITE

that's it!


4. Install from Package "WithSetup"

Please ensure that you have administrative rights for the SharePoint-Farm, the SharePoint-Site and the Sharepoint-Content-Database
on SQL-Server.

Extract the archive and double-click EmbDocumentInhalatorSetup.exe

Follow the instructions on the screen.
