Installing Toolkit on PC without Internet access

I'm installing Toolkit on a server without Internet access.

I have .net 4.6.2 installed but TK insists it can't install without first downloading and installing 4.5.2, which of-course it can't without Internet access. I have downloaded the offline installer and run that but it simply reports that 4.5.2 or a later version is already installed.

How do I work around this?

What is the installer checking to detect the .net version?

(This is a pretty urgent problem as I need to have this server communicating with C-Bus in the next few days!)

 

Additional information: I am installing on Server 2012.

Following the same steps on my Windows 10 Desktop I don't get prompted to install .net Framework, so the OS version may be important here.

 

Yes, we tried that and just about everything else!

4.6.2 was installed.

Manually installing 4.5.2 fails (because 4.6.2 is installed).

On Server 2012R2, 4.6.2, it turns out, is a pre-requisite for the entire desktop server GUI; forcing it to uninstall leaves you at a "DOS" command box after reboot. I did try to get .net and TK installed from there but failed miserably (and I had no confidence I'd ever get back to a working desktop).

We have managed to get around it by persuading site to open up a connection to the Internet from the servers for the duration of the install (they weren't happy about this though!).

I suspect that the easiest "solution" is a commandline switch on the installer to skip the .net framework check?

Looking through the documentation of the library you linked to, it looks like it supports bundling the installer, so it might also be possible to insert the .net installer into wherever the TK installer extracts to ready for install so that the .net installer is present when it reaches that step, but after a bit of playing I've been unable to work out where that would be.
