What prerequisites should I select?
product not working at client site, possible prerequisites problem

I have an excel addin that works on my dev machine in both code and in released form.

It used to also work at the client's site, but has stopped working. The only new thing I added was an ArrayList object, so I am wondering if adding using System.Collections means I have to add a prerequisite?

I already had using System.Collections.Generic before, but had to add the new using clause to allow ArrayList.

In general, how do you know when to add one anyway?

Hello Paul,

I don't think the issue relates to a missing prerequisite; ArrayList type is declared in mscorlib.dll.

Could you please reinstall your add-in, start the host application and check if there are errors in adxregistrator.log and adxloader.log files? Make sure that adxloader.log is updated when you start the host application after reinstalling the add-in.

Hi and thanks for responding so amazingly fast!

Do you mean the logs on my PC or on the client PC?

In which folder do the logs reside? I could not find these files with a search.

To clarify:

The addin installs OK on client machines, and some features work, but it throws an exception near where the ArrayList is used. I can't yet tell exactly where as I am working remotely. The same code works just fine on my dev machine.

In general, I always think if it works on my machine but not at the client, then the code is OK and the environment is not, which is why I suspected a pre-requisite.

Paul,

Please check sections "Get details about add-in registration/unregistration" and "Get details about add-in loading", see the PDF file in the folder {Add-in Express}\Docs on your development PC. Please provide the logs from the machine where the issue occurs.

Ah ha, that's the different issue I believe. I suggest that you debug your code. You can add a number of debug messages to your code; use System.Diagnostics.Debug.WriteLine(). You collect the messages at run time using DebugView (see http://technet.microsoft.com/en-us/sysinternals/bb896647.aspx). If the issue isn't reproducible on your machine, you could instruct the customer to start DebugView and provide you with the log.

Should you need prerequisites, your add-in wouldn't load and this should be reflected in the logs.

Ok that is an excellent answer. I will try to understand how to get the customer to start debugview.
