phpMyAdmin starting problem

I installed the phptriad and everything was okay I guess. When I started phpMyAdmin, it won't start due to an error connecting to mySQL. I try reading the install notepad file with php and it was asking for certain DLLs to be transferred to the System folder, but these DLLs are no where to be found.

So I deleted it and installed instead individually, php, mySQL and Abyss Web Server. But my computer can't still read php files. I was trying to install phpMyAdmin but the zip file (installer) would not open.

Use:

Thanks.
