My VB6 code runs fine on my pc.

But it is throwing up 'Run time error 9 Subscript out of range' error on my client's machine.

I did not use any arrays in my code.

Could not trace out where the error is.

Please help.

Can you post your code and specify the line that is triggering the error? You say you're not using arrays, so it may be a file that it cannot locate.

It could be your Windows Explorer setting, "hide extensions for known file types". You may have it checked and your client unchecked.

error 9 is sometimes returned by the system when a file does not exist... and can be as simple as the extension miss matching and in the most extreme cases its because the file name is a protected name like "con" for example. AND on newer systems because the program has no access rights to a particular directory like c:\ on a win7 machine.
