I just had this issue today (August 9th, 2018).
After removing KB3102467, .NET version was 4.6.00081.
After also uninstalling KB3045563, .NET version was 4.5.51641.
I was then able to install SPF 2013 on 2012 R2.
Unfortunately, .NET Framework 4.7 is the current version but it does not appear in the list of updates or installed programs.
Hi Sam,
Thanks for the reply,
If your current version is .NET Framework 4.7, so you can find the following KB’s bellow in installed programs:
Microsoft.Net Framework 4.7 for Windows 8.1 and Windows Server 2012 R2 for x64 (KB31186539)
Microsoft.Net Framework 4.7.1 for Windows 8.1 and Windows Server 2012 R2 for x64 (KB4033369)
Microsoft.Net Framework 4.7.2 forWindows Server 2012 R2 for x64 (KB4054566)
You need to uninstall all the mentions KB and try.
I was then able to install SPF 2013 on 2012 R2.
After removing KB3102467, .NET version was 4.6.00081. uninstalling this KB3045563, .NET version was 4.5.51641.
Here’s the latest fix that works as of 11-3-2019:
https://docs.microsoft.com/en-us/sharepoint/support/installation-and-setup/setup-error-if-.net-framework-4.6-is-installed
Had the same issue. Rather than muck about uninstalling the .Net framework I just took ownership of the registry key
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Client]
Changed the version from
“Version”=”4.6.01586”
To
“Version”=”4.5.51650”
Ran the install everything worked a treat then just changed the value back again
