InfoPath Dev

I'm trying to convert all of my completed InfoPath forms in a SharePoint repository to TIF format.  I've already created a console application that runs on a separate utility server to poll the List for certain criteria via SP Web services and am able to convert the file using the Microsoft Office Document Writer with the following code:

try

finally

I was informed that I could possibly run the process in the background by opening the document in a different manner.  I attempted to follow another post i saw to open up the document by swapping out the XDocument oDoc = oApp.XDocuments.Open(fileName,1) with the following code:

XDocuments oDocs = oApp.XDocuments;
Type oDocsType = oDocs.GetType();
object objDocName = fileName;
XDocument oDoc = (XDocument)oDocsType.InvokeMember("Open", System.Reflection.BindingFlags.InvokeMethod, null, oDocs, new Object[] { objDocName, null, null });

Unfortunately, I don't know what the expected parameters are for the InvokeMethod and am getting an exception error stating:

Number of parameters specified does not match the expected number

Any suggestions?

So I found a way to make this run in a background process by turning the applicaiton into a Windows Service and using a Timer Job.  This worked fine in my development environment.  However, I am not getting the following error in Production when running the service.

The selected file is an update of a form on your computer. However, the update has been blocked because the author of the file cannot be verified.

I can login to the server using the credentials of the service account that's running the service and it can definitely open up the files from the SharePoint Form library without any issues.  It's almost as if the service account is using an entirely new user profile or none at all when connecting to SharePoint.  It appears to be an issue with Internet Explorer settings.  Does anyone have any suggestions?

I found the answer.  Turns out that the system still had a cached template of the one from my dev environment.  Even though i tried the "infopath /cache clearall" while logged in as the account running the service it still kept pointing to the old template.  I ended up doing a search for the physical folder that did the trick.  Make sure to delete out the contents of the following folders:

 - C:\Documents and Settings\Default User\Local Settings\Application Data\Microsoft\InfoPath\FormCache2

- C:\Documents and Settings\<<serviceaccountuser>>\Local Settings\Application Data\Microsoft\InfoPath\FormCache2

 This is what did it for me.  Now my service runs without opening up the form in the Foreground.
