I am having a problem when running a C# console application that refers to an unmanaged COM dll from a Scheduled Task.

Scenario 1:

Run the application directly from the installation folder

Result 1:

Applications completes successfully

Scenario 2:

Run the application from a scheduled task where 'Run only when user is logged on' selected

Result 2:

Application completes successfully

Scenario 3:

Run the application from a scheduled task where 'Run whether user is logged in or not' selected

(I am still logged in and am manually running by right-clicking the scheduled task and selecting 'Run')

Result 3:

FileNoteFoundException thrown for referenced COM dll, as below:

Application: ExcessPaymentUploader.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.IO.FileNotFoundException
Stack:
   at Gelder.Exchequer.DataServices.ExchequerTransactionDataService.GetDebtorTransactionsYTD(System.String)
   at ExcessPaymentUploader.Program.CreateExcessList()
   at ExcessPaymentUploader.Program.Test()
   at ExcessPaymentUploader.Program.Main(System.String[])

The console application is installed on a Server 2008 R2 box.

The required dll is under the same folder as the executable.

The dll is registered.

Has anyone come across this issue?

Thanks

Nick
