like UniZero said, you have very old versions of java (2 actually)
Code:
[09:54:40] [INFO] JavaFinder.parseWinJavaVersion:137: Java Version: 1.7.0_51 sorted as: 1.7.0_51 32 Bit Java at : C:\Program Files (x86)\Java\jre7\bin\java.exe
[09:54:40] [INFO] JavaFinder.parseWinJavaVersion:137: Java Version: 1.7.0_04 sorted as: 1.7.0_4 64 Bit Java at : C:\Program Files\Java\jre7\bin\java.exe
[09:54:40] [INFO] JavaFinder.parseWinJavaVersion:137: Java Version: 1.7.0_51 sorted as: 1.7.0_51 32 Bit Java at : C:\Program Files (x86)\Java\jdk1.7.0_51\bin\java.exe
[09:54:40] [INFO] JavaFinder.parseWinJavaVersion:137: Java Version: 1.6.0_15 sorted as: 1.6.0_15 64 Bit Java at : C:\Program Files\Java\jdk1.6.0_15\bin\java.exe
[09:54:40] [INFO] JavaFinder.parseWinJavaVersion:164: FTB Launcher Prefers: Java Version: 1.7.0_04 sorted as: 1.7.0_4 64 Bit Java at : C:\Program Files\Java\jre7\bin\java.exe
put simply, the launcher found: Java 6, update 15 64 bit (JDK); Java 7, update 4 64 Bit (JRE) and Java 7, Update 51 32 & 64 Bit (JRE, Latest)
your error however, apears to be that the minecraft jar is missing: File Not Found: C:\Users\Quintas\Desktop\Ph \versions\1.6.4\1.6.4.jar
after you have sorted java, run a force update on the modpack and try again
