Firefox 50.0.2 not installing

[Phenomic]

Setup says, "Firefox can't be installed. This version of Firefox requires a processor with SSE2 support...". The app compatibility launcher doesn't help. My W2k is a virtual machine, and current Firefox is 48.0.2

Does your actual processor support SSE2 support?

[Phenomic]

Yeah, it's a Skylake i7-6700

...and of course I have Windows2000-UURollup-v11-d20131122-x86-ENU

That's good news! Then the problem is the virtual processor your hypervisor is showing to FF does not support SSE2.
In this case all you need to do is to find out how to configure your hypervisor to show a newer virtual processor (one that supports SSE2). Now, as to how exactly do you do that, it depends on which hypervisor are you using, and then, they certainly have a support forum that can offer you more detailed specific support and help.

VirtualBox runs FF 50.0.2 in Windows 10 just fine. Could it be Firefox has dropped Win2k even with UU rollup?

This has been discussed in the W2k SP5 thread and the KernelEx thread; it’s possible that you need BWC KernelEx 2.8h or newer, but do check out the info for yourself, as it’s not something I’ve had the opportunity to deal with myself just yet.

Thank you, that worked, link is:

A dialog box popped before install with "Kernel Options", I left everything at default.

Amazing, how does BWC compile the kernel without source code?

He is amazing, that’s for sure, and it’s good you were able to install his new kernel on top of your UUR, as sometimes that can be problematic.  And maybe, just maybe, a new UUR is in the offing…another something to look forward to in the season of hope.

I see there is a newer version

http://w2k.flxsrv.org/cgi-bin/dl.cgi?file=Windows2000-KB935839-v28i-x86-ENU.exe

and

http://w2k.flxsrv.org/cgi-bin/dl.cgi?file=Windows2000-KB935839-v28iG-x86-ENU.exe

Which one should I use? Should I uninstall the 28hG first?

I downloaded this file but it complains about needing KB2722913. That is a 3.0GB file containing all security updates in 2012. I guess the UURollup from 2014 does not include this, since I am running that version (Windows2000-UURollup-v11-d20141130-x86-ENU.7z).

Is there a way to access just the IE6.0SP1-KB2722913-WINDOWS2000-X86-ENU.EXE by itself?

Yes there are a couple of IE6 updates that are necessary, you download & install them separately from MS or tomasz86 archive.
