Deus Ex SDK Install Issues

Alright, so historically I've always been pretty prepared for doomsday scenarios with Deus Ex and its SDK components. Been a while since I've been on DX Alpha, but this issues has 2 routes.
Installed a Deus Ex clone into a directory clone, patched said clone, then tried to run SDK installer. Tried running said SDK installer in compatibility mode and with/without admin, but any which way I run it it comes with:
Failed opening destination file: C:\DeusEx\System\UCC.exe (Access is denied)
The destination drive might be full, or it might have bad sectors.
Just finished reformatting ye old PC and haven't played with anything major since the first time I installed DX onto my PC. I don't think SDK is gonna run or I have a way to coerce it or crack its contents out in some brute force manner, if even, so my questions are this:
Does A: Anyone know how to bypass this error and get the SDK installer working? Has anyone had similar issues, and can they be resolved?
or does B: Anyone know how to tweak the registry and subcomponents associated with a DX SDK install necessary for UED to bootup? For instance, after supplementing some DLL's as usual:
"Component 'THREED32.OCX' not correctly registered: file is missing or invalid"
This is a fun one I haven't run into before, so I'm pretty stumped, and this is the deciding factor between being able to run or not run UED on my pc post-formatting.
Thanks for your time, WCCC
