Hi there!
Clean install of AIDA64 Trial on 3 XP, SP3 boxes, fully updated configurations.
Install went just fine, using your .exe download. When trying to start the app, there is only a small red "64" box in my system tray and then the system is totally hung.
Managed to see the Main Screen only once. No choice but to do a hard reboot. When using the version previous to this one, namely 5.95.4500 Extreme, all is perfect.
I submitted a ticket, but I would like to confirm with other users.
TIA!
