It appears the CDs are from a place that offers zero support. As it appears that no support is from the CD's supplier why not take those CDs and machine to some repair counter if your PC guru friends can't fix it?
I have vista for os and I have been battling with trying to get the cd to play for 2 days now. I have gotten the program to appear on the screen but when I push say,+ part one fractions or any of the commands, table of contents..nothing I have installed or tried to upgrade my QuickTime like it instructed but I get an error.500 I changed my default once to try IE and when that didn't work I change the default to Foxfire. I went and downloaded DirectX Sample browser to tell you the truth I don't know what prompted me to do that, should I uninstall? I click on computer and right click the DVD Introductory and still no results and I don't know what else to do. This all for trying to prep for getting into college, scary huh? I'd give anything to be knowledgable on the computer. Please help me
Light bulbs you shouldn't buy
There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
