While IDA-STEP installation is in progress, a message box with the
following error appears: "Insufficient disc space on drive
C:".
Cause
The installer requires about 100 megabytes of free disk space to
expand
in order to complete your IDA-STEP installation.
Solution
Delete files that you do not need from your C: drive (or whichever
drive you are installing to), to create sufficient free space for
the
IDA-STEP installation.
