You can create this report by using the built-in report "Software: All Microsoft software", removing the criteria from SoftwarePublisher and adding the following criteria on SoftwareName: Like 'Microsoft .NET Framework%'
I added the report below for your convenience.
Select Top 1000000 tblSoftwareUni.softwareName As Software,
tblSoftware.softwareVersion As Version,
Count(tblSoftware.SoftwareID) As Total
From tblSoftware
Inner Join tblAssets On tblSoftware.AssetID = tblAssets.AssetID
Inner Join tblSoftwareUni On tblSoftware.softID = tblSoftwareUni.SoftID
Inner Join tblAssetCustom On tblAssets.AssetID = tblAssetCustom.AssetID
Where tblAssetCustom.State = 1
Group By tblSoftwareUni.softwareName,
tblSoftware.softwareVersion
Having tblSoftwareUni.softwareName Like 'Microsoft .NET Framework%'
Order By Total Desc,
Software
