B4J Question Compiled program problems

[oldeast]

Hi all,
I created a program CMS for Windows that uses a SQLite database, the database is created in the c/users/yourname/appdate/roaming/CMS on the first run.
It works perfectly on my computer.
I can delete the database and its reinstalled with no problems when the program is restarted, I can add and delete records.
Two testers downloaded the .exe file, we are all using Win Defender.
The two test sites have no problem installing the program which creates the database and adds a test record correctly. As soon as they try to view that record the program shuts down.
Where should I start looking for a solution, any suggestions appreciated.
Thanks

Look in the Logs, do you get any error.
For test, try to copy it directly under C:\ to see what happens.

Thanks Klaus, copied and tested as you suggested, ran it under the cmd line, no errors, all good, can add/edit records..
my tester downloaded the new .exe, again all good so that's better, but when she tries to add a record, the new record form appears blank..
Have asked how much RAM is on that machine...
it has 8gB..mine has 4..
update
the second test person has installed the file and it runs no problems on Win 8 so not sure where to go from here

I will review the way the program opens the form to edit or add a record to see if I can simplify it.
Thanks for your input and advice.
