Ok, photogallery.msi is part of the
software package that comes with an HP product...
It is an MSI (MicroSoft Installer) file, meaning it contains installation information for the Photo Gallery software.
Unfortunately, this installer file often conflicts with other software until it is fixed.
Chances are your friend/tester is getting this..because he or she uses other imaging software..
I shouldn't get this error..because I use HP..
I have downloaded video in. flv
The images used to make this video..Perhaps that's what's giving you the error..?
