FNIS, Step 2.2.9.1, and Windows 10 x64 - FINS won't run

[MarkInMKUK]

Note: This may have existed in the preview stages of Windows 10, but I didn't run FNIS during the time I was testing the preview and so used my pre-existing Windows-7-Generated setup, which worked.

Problem: When I run FNIS (FINS Behaviour v5_5 and the corresponding fix 1 file, merged), I get the following error message:

"GenerateFNISForUsers.exe - This application could not be started.

This application could not be started.
Do you want to view information about this issue? Yes/No"

 

Clicking "Yes" repeats the error message exactly as a second popup, and links to https://support.microsoft.com/en-us/kb/2715633

which is entitled "Shim errors for the .NET Framework version and platform support"

Attempting to enable .NET 3.5.1 within Windows and rebooting has not changed the error message.
  Any suggestions to try next, please?

Did you install FNIS into the mod order and make sure it's checked in the left hand pane of MO?

Thanks - now I *know* I've been at this too long today. I forgot the checkbox. How do you remove a mispleading and idiotic post?

[DoubleYou]

You don't, because this is like one of the most common mistakes with FNIS in MO, and believe me, everyone does it.

How do you think a NOOB like me knew the answer
