Well, I have just completed a project requested by a client. The program was well tested that no error occur and everything worked as expected before delivery.
The client was called up and I went to their place and installed the program.
Just at the demonstration of 2nd step, the program encounter an bug where the Table did not load the data. What!!??
The client looked at me like saying: "Have you even test your program before coming here?"
This was kinda embarrassing. I told them that the program run well in my computer.
I immediately turned on my laptop and checked the coding >> no error found.
Then I tried again by erasing all data in database and retest >> still... everything worked fine.
The client suggested me to try to run the program on 2nd computer in their office.
Alright.... 2nd computer... and.... No Problem!!! Everything worked just as expected!!
What the....???
I really have no idea why the 1st computer was not working, but the 2nd computer worked.
So, I will have to leave the office and told them that I will return after a few days after I have solved the problem.
Well, now I am trying to find an error that will not occur in my computer

Have you tried switching it off and on again?
Sounds like it could be an outdated, corrupted, or missing library. Try running SFC, and (re-)installing any VC redists, etc.

If you can identify the area where it goes tits up you can write in logging messages to narrow down the failing function. Does not your error trapping show you the error or is it just the code works but you get no data.
I have a function that writes a table to an object, if there is a mismatch of data types the transfer fails. Some older systems may not want to support all the data formats you use.

Error trapping? What's that?

I was going to write exactly this. This is where logging will save your bacon - every time.
Don't underestimate the usefulness of detailed logging. Also make your log files easy to read and search (I'm looking at you, Microsoft).

I've had cases like this before. Usually it's something like a missing or conflicting library. Not fun or easy to troubleshoot unless you can reproduce in development. Good luck!

Like others have suggested, is there a library that's loaded at runtime that is missing? Easiest way I know of to find issues like these, is to do a base OS install into a fresh machine (e.g. VM), then install and test. Usually, it works on your machine because of something unrelated that you installed and brought with it a library you're unknowingly dependant on (typically, a MSVC runtime version, in my experience). Make sure you test with the exact version of the OS that was on the customer's machine where it didn't work.
Also in my experience, if it's not a library issue, then it's almost always a race condition.
We can program with only 1's, but if all you've got are zeros, you've got nothing.

Ours very occasionally forgets to output any sound, so I have to apply my years of computer experience, and unplug it, count to ten, and plug it back in. While sounding really technical.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

I tried this, but I failed to count to ten because I was not sure whether I should start from 0 or 1

Depends - is your brain written in C# or VB?

c++ at the moment. But I have to mention I need to work with Embarcadero so far ... if you know what I mean ... where string class (and only string class) is index "1" based 
On the other hand this helps me to stay flexible, I mean a programmer should be able to handle this

Or are they both Logitech Harmony remotes, and each one has reached its maximum device capacity?

I also get to sleep in the other room. Such a peaceful night's sleep.
