Hi there,

When I want to install a small software downloaded from the internet this error told me that something might be wrong. I didn’t try to install it again because I am afraid that might harm my laptop. Can anyone explain me what is this all about? What this error means?

Hello,

I was having issues with getting my PhotoSmart 309g to work with Snow Leopard. I wanted to uninstall this software and try again, but I am unable to do so because of an error. I cannot proceed with uninstall due to a missing uninstaller plugin. What is causing this error? Can these missing plugins be replaced somehow? Or can you suggest a work around for this issue that would enable me to uninstall the software without these plugins? Please help me out. Thanking everyone for spending their valuable time on this issue. Regards
