Unknown publisher warning

Lou[NE] · From: Weston, NE USA

My wife's computer is giving warnings about "Unknown publisher - no valid digital signature - are you sure you want to run this software" when she opens a particular game (Gold Mahjongg) and also Mailwasher Pro.

Didn't use to - now it does. Any suggestions on how to stop this? System is Window XP Media Center with SP3. I installed SP3 a couple weeks ago, but she says it was hsppening before that.

I have the same OS on my computer (also with SP3). I get no warning when I run the game. Don't know about Mailwasher on my pc as I don't use it.

It's MS trying to "protect" you from yourself. Most likely the program uses ActiveX or some other MS library integrated into IE. Digital signatures cost money and many small companies and independent programmers can't afford them (especially for free stuff!). Try this:

Go to Tools > Internet Options
Click on the Security tab.
Check the box that says "Allow software to run or install even if certificate is invalid"
