after reading the log file i found this command which i manually executed in command prompt with some modifications and its done!!!
Process.Start: C:\Windows\system32\msiexec.exe /quiet /norestart /i "c:\338f6462408072c851cf3b1e\Packages\AppFabric-1.1-for-Windows-Server-
64.msi" ADDDEFAULT=Worker,WorkerAdmin,CacheClient,Setup /l*vx "C:\Users\Administrator\AppData\Local\Temp\AppServerSetup1_1(2013-03-05
18-06-39).log" LOGFILE="C:\Users\Administrator\AppData\Local\Temp\AppServerSetup1_1_CustomActions(2013-03-05 18-06-39).log"
INSTALLDIR="C:\Program Files\AppFabric 1.1 for Windows Server" LANGID=en-US
Then remove the words Process.Start: and /quiet and execute the command as administrator in MSDOS
C:\Windows\system32\msiexec.exe /norestart /i "c:\338f6462408072c851cf3b1e\Packages\AppFabric-1.1-for-Windows-Server-64.msi"
ADDDEFAULT=Worker,WorkerAdmin,CacheClient,Setup /l*vx "C:\Users\Administrator\AppData\Local\Temp\AppServerSetup1_1(2013-03-05 18-06-
