I just downloaded Defraggler v1.03.093 and installed it on my laptop. Dell Latitude D620, 2 GB RAM, Intel Centrino Duo 1.6 GhZ, Windows XP SP 3, 35 GB free space on HD, Mobile Intel 945GM Express Chipset on board graphics chip.
When I started Degraggler it displayed the UI very briefly, 1 to 2 seconds at most and then simply crashed to the desktop. Checked running processes and don't see it listed post crash.
I uninstalled v1.03, downloaded the last v1.02.xxx and installed it and had the same problem. I tried to run the debug item but couldn't find the log file.
Thoughts on what to try next?
