Keil Compilation issue with linking OBJECT FILE "FILE: RAM.OBJ"

Hi,

I'm trying to upgrade the Compilation Process followed in my old code which was working with 16-bit keil compiler ,now with 64-bit keil compiler.Following are the steps done below:

1. Installed licensed keil 64-bit c51 version.
2. copied the C51,A51,BL51,0H51 binaries to my project folder.
3. provide the compilation of each file in .bat script.
4. Now while executing the script i'm getting below error:
   *** FATAL ERROR L218: NOT AN OBJECT FILE
   FILE: RAM.OBJ
5. But i'm  able to generate the RAM.OBJ file.

Please help me understand where I'm missing the compilation process.
