Software Deployment

Setup for this is pretty easy.  I have done it for my Org.

1. Extract Viso from the ISO onto your hard drive.  Lets say you did it right to C:\visio
2. Setup a Visio .msp file.  To do this, run the setup.exe with the /admin switch.  Example: c:\visio\setup.exe /admin
3. Set your Org name
4. Set you Licensing information - KMS or MAK
5. Accept the license agreement
6. Set your Display settings for a progress bar or not - None, Basic or Full.  None = silent
7. Change anything else you want to change.  The above should do everything fine if you want it basic.
8. Save the .msp file to the "Updates" folder where your Viso is extracted to.  In our example c:\visio\updates
9. Zip all the folders\files in the c:\visio folder.  IMPORTANT: do not zip the visio folder, zip the contents INSIDE the folder.
10. Go to your K1000 > Distribution > Choose Action > Add New.  Select the software you want to associate the zip installer with.  If you havent created it before, select "Also Show Software without and Associated File" then filter for Visio.
11. Upload & Associate New File - Browse for your Zip of Visio
12. Run Parameters = setup.exe
13. Set Managed action of when to install
14. Select the computers you want to distribute to and other settings you want.

First read this post, it explains the two ways you can do it. I prefer the XML method as its easier.

XML Method
Have a look at this post, to see another example.

In the Visio directory you should have a config.xml (I think, I cant remember), make a copy of that file, open it up and make the require changes. The <Configuration Product="xxx.xx.xx">    will already be populated so you just need to fill in the other bits. See below.

  <Display Level="none" CompletionNotice="no" SuppressModal="yes" AcceptEula="yes" />  <Logging Type="verbose" Path="%systemroot%\temp" Template="Microsoft_Visio2007Install.log" />

And this bit for the product key

 <PIDKEY Value="AAAAAABBBBBBBBNNNNZZZZZZZ" />

And any other bits in the XML you feel you need to populate.

Install using this

 setup.exe /config .\<name of config>.xml 

Remove using

 setup.exe /uninstall <name of OfficeProduct ie VisPro> /config .\<name of config>.xml

I dont use KACE, so someone else will have to help you there, and make sure you have enterprise media/serial or else it wont work.
