Unable to Use Legacy support of ARMv7 and no board support for NPC2148 on Keil_Vision5

Ohk so i have  a keil_uVision5 on my device and i have to work on LPC2148 and ARM7TDMI but my MDK Lite version 5.43.00 doesnot natively come with the packages for the same. Can i get those exe installers for these realted packages to make this work. I have already installed ARM compiler version 5.06 update 7 (build 960) but then when i  build a target program on target device of NXP LPC2148 i get the following error on  

build output :

I am extremely new to this and our course has only thought us about ARM7 processor and sadly nothing about Keil so i am running in the dark here, I know the basics of how this works but i am not able to solve this problem so i would be thankful if you could help me and also share some resources to develop my skills with thi software. Right now our course is teaching us about ARM7TDMI and its ISA and i hope to learn more about Computer architecture through this so any suggestions will be extremely helpful
