We have installed the GDC on Wyse - Windows XP thin clients. These were upgraded from GDC 1.31.1e to 2.22.03 and then 2.32.08. The upgrade from 1.31.2e to 2.22.03 caused us to purchase USB sticks because the internal disk was not large enough to contain the larger GDC.
...
... to avoid unnecessary alarm, I'll clarify the above. Those particular clients had 200MB drives. Before the GDC was installed there was approximately 40MB free. The 1.3x GDC used <5 MB. When that customer migrated to 2.2x GDC, which took slightly less than 40MB, suddenly space became an issue.
The 2.4x (and 2.3x) GDC have been on a diet and should come in at less than 30MB.
Lesson is if installing onto the thin client itself, check disk space.
