My client has reported issue on below logic that IMGRETRV.EXE is not launching by Acu cobol program. But, if i click on IMGRETRV.EXE ,then it is launching, but, why ACU cobol program is not launching IMGRETRV.EXE using below logic, please note my client has reported in their few PCs  IMGRETRV.EXE is not starting by acu cobol program!

ACU cobol has fault functionality or my program has fault?

==========

* Build the SYSTEM call command line:
Move spaces to WD-X80.

If LS-USER-TYPE-DEV 
   Move "ETC\\IMGRETRV.EXE" to WD-X40 
else
   Move "ETC\\IMGRETRV.EXE" to WD-X40
End-If.
String "C:" 
LS-DIR-PCPATH-VALUE 
WD-X40 
delimited by spaces into WD-X80 
End-String. 
If LS-DIR-PCDRIVE-VALUE > spaces
Move LS-DIR-PCDRIVE-VALUE to WD-X80 (1:1)
End-If.
* Check for executable: V.10.02
Call "C$FILEINFO" 
using WD-X80 
WFile-Info 
giving WExit-Status 
End-Call. 
If WExit-Status = zero AND WFile-Size > zero

else
   Move 9031 to IMGEVIEW-RETURN-CODE 
Go to XImage-Call 
End-If. 
* Call SYSTEM:
Call "C$RUN"

on exception
Move 9991 to IMGEVIEW-RETURN-CODE

There is a lot going on in this post.  Clicking on IMGRETRV.EXE typically means your environment has all of the executables needed to run that particular software. If  you use a command prompt and cd to C:\\etc, then type in IMGRETRV.EXE and enter, does that application run?

There may be some environment variables (or dlls that reside in the PATH env variable) that IMGRETRV.EXE relies upon to execute. If  IMGRETRV.EXE runs from the C:\\etc directory, try using C$SYSTEM instead of C$RUN in your COBOL program.
