Installing BDE BDE5_UPG.EXE fine on Win95 Not on NT

I installed BDE version 5.00 using bde5_upg.exe found on the Inprise website
on a Win 95 machine. It installed and runs fine.

Tried to install the same exe on Win NT 4.0 and I get "Windows Temp file may
be too small"??? as it is setting up to install.

Has anyone else experienced the same and if so any help would be
