"Creative Projects" hassle

Out of the blue, a program called Creative Projects, Microsoft Fusion 2.5
started to try installing on my computer, through a Windows Installer.
After gathering data, it then produces a message box "The feature you are
trying to use is on a network resource that is unavailable. Click OK to try
again, or enter an alternate path to the folder containing the installation
package 'creativeprojects.msi' in the box below." Then below that is a
BROWSE button, and a box for the path. The current path shown is:
C:\hp\tmp\src\scancam\hpsw\setup\creativeprojects\ creativeprojects.msi

It seems impossible to get rid of it, it's in a loop and just keeps trying
to install. Rebooting does not help.
Any ideas?
