Web service running an executable

I have a web service that must run an executable. To run the executable in C# I am using the Process object.

The service runs the executable when I run it locally through visual studio. That is, it is converting a file and putting it in the output directory.

When I run the service on the production server the file does not get converted nor put into the Output directory.

I know that I am passing in the correct parameters to the executable because I had the service output the full path and parameter. Then I pasted the full path and parameters into a command window on the server and it properly converted the file and placed it into the Output directory.

So I know the executable and its parameters are working on the server, but just not through the service.

I have confirmed in IIS that the service has Executable Permissions on "Scripts and Executables."

I am not sure what else to check or how else to test.

I had my web service call and run a file un-zipper. I gave it the path to the executable and arguments for the archive I wanted un-zippped and the destination. This worked fine.

When I point it back to the exe I need run it fails. Here are two more points:

1) I have given Everyone full control of the folders, subfolders, and files.

2) The exe I need run is 16 bit. Would that make a difference?

3) I was able to get it to return an error using proc.StandardError. The error is: "This application has requested the Runtime to terminate it in an unusual way"

This is running on Windows Server 2003.

Any thoughts, ideas, or insight?

Thanks! Mark

Mark,

Ensure that you've got the path to the excecutable as per the fully qualified path on the server, i.e.:

e:\private\exe\businesscat1\yourexe.exe (etc,etc)

of course, it could also be something being invoked by the exe that isn't present that is being referenced.
