My NW65SP4 install is frozen at "Extracting ..."

The only potential problem I can see is that, if I look in Monitor, it says
my 4000 MB capacity SYS volume is 83% full. I copy NW65SP4.EXE to the root
of SYS, extracted it there (creating an NW65SP4 folder with the contents in
a directory structure below that) and ran the IPS file.

What should I do now? I have another volume onto which I could copy the SP
and run it from there, or even could create a version on a CD without the
non-English files.
