Ah interesting.
Wonder why it can't update reg without admin.
Interesting that it's in WOW6432
What that means is "Windows on Windows 64bit 32bit
So it's a kinda virtualisation subkey. On ye old windows 9x it's NOT in that area at all.
Are they running within DGvoodoo in a much higher res?
The 9x version might be one of those unique editions that doesn't work with that install method I wrote and chose.
I'd have to have a copy to figure it out.
The reg keys should be somewhat straightforward, but it does mean we have to figure out the Mw2 GBL and mercs keys - and any subversions eg 1.1, 1.5 etc
So a whole new layer of potential annoyances.
re-uploaded the above installer with the typos fixed.
