Update: I have another post that shows the count of ms office version with architecture type 32 or 64 for specific collection on http://eskonr.com/2017/11/configmgr-report-for-count-of-ms-office-versions-with-architecture-type-32bit-and-64bit/
I wrote a blog post year ago on how to get count of MS Office Editions with versions installed across my environment using SCCM Configmgr. This report consists of 2 reports .1st report is ,to get count of Microsoft Editions for ex: how many are office 2003, 2007 ,2010 and 2013 and 2nd report is actually drilled report linked to 1st report to give list of all MS Office editions (what are the editions of office 2003 ,2007,2010 and 2013) with its client count .
Many of my blog viewers have requested through comments and some of them are via social networking sites ,that they want drill down the 2nd report to see the list of clients with each office edition and version.
Having drilled report to see the list of clients will certainly help to investigate and upgrade them to latest version of Microsoft office.
You can always create collection for office editions but having a report like this would help to export them to excel and other SSRS supported formats.
This request is pending from very long ,it was lying in my to-do list and finally going out through this blog post.
So what all you need to get this report (Count of MS office editions ) implemented in your SCCM site ?
Download the 3 reports from the TechNet Gallery ,upload the reports into your SSRS folder (make sure they all in same folder),change the data source for each report and you are good to run.
Note: This report will list only Microsoft Office 2003,2007,2010 and 2013 but not office 365. If you need office 365, you may have to wait for next update ,otherwise you can edit the RDL file and customize it.
How does the report look like ?
1. Count of MS Office editions
2. List MS Office editions for selected version (ex: 2003)
3. List of Clients by specific MS Office edition and version
Hope it helps.
