I tried your SP-trial 18.104.22.168 on XP SP3 with Avira antivirus V10, and got an error message:
"Error Movefile code 32" (see attachement), for many files in the installation directory.
SP start an infinite cycle "restart windows, ...".
Trying to install it with Avira (Guard, Mailguard, Webguard), desactivated and got the same problem.
Installing SP under Windows safe mode solve the problem.
Desinstalling AVIRA V10 and installing SP, solved the problem.
Is there any fix, as i do not want to buy this product if I get other "Code 32", using it later.
Note that i saw a post relating the same problem with an older SP version:http://www.stickypassword.fr/forum/view ... =30&t=6527
Thanks for any anwser.
