Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release

Switch your profile on the MC launcher to point to java 7, not 8 (hit Edit Profile. Change path under JVM->executable).

I just change the 8 to 7?
ohh wait I just went to the location realized I Don't have java 7 installed it

Er...no. There should be a file path in there already listed. Follow it in your explorer until you get to the folder that holds the java folder with 1.8.0_25 in the name or something like that. In that folder there should be another one with 1.7.0_xx in the name assuming you have installed java 7 at some point. So redirect the file path (rewrite it) to the .exe inside that 1.7 folder instead of the 1.8 one.

Got it to work thank you very much sir.

and I added my mods in,I accindely added my 1.7.2 mods in,I delete them tested Mc and didn't work I will restart Launcher open MC and post what it says

I can't tell with your latest report as it's cut off, but note that your previous one had a whole bunch of 1.7.2 mods which cannot work in 1.6.4. I'd recommend you make sure all your mods are for 1.6.4.
