Most likely you have not installed File::Find::Rule Try this code without calling any modules 
sub fullPathFileName #($StartDirectory,$RegularExpression)

    my(@A,$e,$C,@B,$a,@C,@Dir,$InputDir,@AllTestSuitefiles,@TestSuitef
+iles,$p,@FullPath);
    #Purpose is to extract all paths to directories and subdirectories
    @A=`dir $StartDirectory /s/w ` ;
      foreach $e (@A)
      {
