you may either update kernel32.dll with that API available(i.e. WindowsXP-KB936235-v2): http://kmeleonbrowser.org/forum/read.php?19,143253,page=10

Both, very old (end of 2017), links to WindowsXP-KB936235-v2 (EN) and/or WindowsXP-KB944340 (EN) return 404 currently  ...

I'm using SP2... maybe that's the issue?

yes it is always an issue because GetLogicalProcessorInformation is missing in XP SP2.

you may either update kernel32.dll with that API available(i.e. WindowsXP-KB936235-v2): http://kmeleonbrowser.org/forum/read.php?19,143253,page=10

or patching your target application with kernelxp and patchk32. https://github.com/roytam1/rtoss/tree/master/kernelxp

a patched SP52 running on just-installed XP SP2 VM:

To make all new versions of Roytam browsers work under XP SP2, here is the simplest solution...

download:CFF-Explorer.exe
https://ntcore.com/files/CFF_Explorer.zip

Launch CFF Explorer.exe and open the file in the Roytam browser
Open concrt140.dll, click on Import Directory, and then click on kernel32.dll
then click on the line
00037E0A - 00037E0A - 0256
 and Change the function name from "GetLogicalProcessorInformation" to "FindNextFileA",
and then Click on Save.

do this for all roytam browsers and it now works for xp sp2.

my UXP IA32 builds works on any processor that has CMOVcc, which Pentium II and Cyrix 6x86MX/MII and later will work.

and in the past I did tried to make firefox compiling on VC2013 as far as possible: https://github.com/roytam1/fx-vc2013

and NM27 also has many changes in fx48 and even later versions (thanks arctic-fox forks for the job).

but too many efforts put in and no much outcome achieved so I focused on UXP again.

Yep,the fork of 48.0.2 might be unnecessary but i've wanted to one day maintain it...

You can fork it and merge changes to it...
