The update should work just well even if you’re not logged on as an admin.

Do you use the fast user switching feature of WinXP?
Does the non-admin account has enough rights to the temp directory? And to the avast\data directory? (assuming your hard drives are formated as NTFS; you can check this using the Security tab of the Folder Properties in Explorer).

Please tell me how proficient you are with computers so I can select the appropriate wording. :slight_smile:

Thanks
