Runtime closes when I use DoCmd.OpenForm - vba

Question

I have a form with a button which opens a new form to add a new record to a table.
In Access on my PC (full version), everything works.
When I try to run it on a server with Access Runtime, I get an error saying something like:
this application has stopped working due to a runtime-error. The
application will now be closed
(I have the Dutch version, so I hope this comes close to the English dialog box message).
I debugged the VBA, but that doesn't seem to be the problem.
It has worked before:
Private Sub Knop62_Click()
DoCmd.OpenForm "Machines Toevoegen", , , , acFormAdd, _
acDialog, OpenArgs:=Me.Installaties_Id
End Sub

Well any un-handled error in the runtime will spit out the error message, and then as you experienced exit the application.
there are a good number of ways to approach this:
Improve error handling - make sure you don't encounter any un-handled error. I find this can be a LOT of work.
Another way? Compile your application down to a accDE. When you use a accDE, not only does the runtime ignore errors, not only does it NOT shut down?
It also means that all of your local and global variables are NEVER re-set. so global vars, and even global reocrdsets or anything else will retain their values, and do so even with errors. As a result:
Your application runs like a un-stoppable fright train.
Your local and even global variables retain their values. This allows use of application wide settings and variables that never re-set. And no re-sets ever occur even for un-handled errors. They remain intact for the given session (since the time the application was launched).
So, I would try running your application as a accDE on that server. It will not only become vastly more reliable, but it will also not shutdown on un-expected errors and even better it will retain the value of variables even when having encountered errors.
So it looks like you have some un-handed error. You can go on a treasure hunt to find this error, or just try a accDE in the meantime, and perhaps in the new years you might eventually track down the error or issue. But until then, just compile your application as a accDE.
To compile:
First, from VBA editor (just hit ctrl-g). And from the menu bar choose debug->compile. You MUST ensure that no compile errors exist before the next step.
If above compiles, then from UI (main ribbon), go file->Save and publish
From that panel, choose Make ACCDE.
Access will compile your application into a "access executable". Now try running this application with a accDE file extension on the other computer.
