Hi guys, great forum by the way. Ok my problem started when I saved a few JPEG images to my computer from a trusted website (http://wall.alphacoders.com/) When I tried to open the images I got the following message: " RunDLL Error Loading C:\Program Files\Windows Photo Gallery\PhotoViewer.dll The system cannot find message text for message number 0x%1 in the message file for %2. " Screenshot of Image: So i deleted the images and re-saved them to computer and tried again but still nothing, I then realised ALL images on my computer (all types, not just JPEG) refused to open and gave the same message, Also all other media and apps are working just fine. So I re-booted Still not working, so I did a complete clean using the fantastic AusLogistics, Disk-defrag, Disk-clean up, Install-clean up, you name it! I did it all Re-boot, still not working So thought it may be security based. I did a complete scan using: Avast! Anti-Virus 4.8 Proffesional Edition AVG 8.5 (Premium) Re-boot, STILL not working. I have tried everything I can, so now im coming to you guys for help please help!
