I have seen this 3 times in the last week on WIndows XP Sp2 systems. When I open Spywareblaster 3.51 and attempt to manually update it a dialog box opens asking for the Office Install CD to complete an office installation. 2 of these systems have Office 2003 and 1 has Office 2000. Any Ideas? Office runs fine on all 3 systems and this only happens when I click the "Check for Updates" button.
