JBuilder 3.0 wont install

[John Stevenson <John@oa.nl>]

Hello,
I have been trying to install JBuilder 3.0 from Inprise but
keep getting the same error message:

----------------------------
Warining !!  Not enough disk space

The Installation requires 16.57 MB of free disk space but
only 0.0MB are available in .....

---------------

I have over 200MB free and set the permissions on the
directories rwx for everyone (a bit overkill).  I can only
assume that there is something wrong with either

*The Sun jdk 122
* The JBuilder Install

I am running potato debian distribution, last updated
december 14th, with sun jdk 122 .

Anyone had the same problem??
I am going to try get a responce from Inprise also

John.
