Pilote Olitec Clé Usb Nano Wifi N. Believe me when I say that I've tried all suggestions I could find here: disabled AV and firewall, completely cleaned out all old versions, no TEMP files, absolutely no Acronis items anywhere in the registry including CurrentControlSet, etc. I've also tried extracting the MSI package and running it with verbose logging. The installation process barely starts and halts almost immediately with a status 1603 error and the following final notes in the log: === Logging stopped: 2009-12-03 13:36:51 === MSI (c) (F0:18) [13:36:51:747]: Note: 1: 1708 MSI (c) (F0:18) [13:36:51:747]: Note: 1: 2262 2: Error 3: - MSI (c) (F0:18) [13:36:51:747]: Note: 1: 2262 2: Error 3: - MSI (c) (F0:18) [13:36:51:747]: Product: Acronis True Image Home -- Installation failed.
