Acrobat Pro 9 IAC Detect Corrupt File (TIFF)

Question

I am trying to convert a huge number of tif files into pdf files, and most of the time the code below works fine, using the IAC to control Acrobat.
try
CAcroAVDoc avDoc = new AcroAVDocClass();
avDoc.Open(@"D:\Bad Files\file1.TIF", "");
CAcroPDDoc pdDoc = (CAcroPDDoc)avDoc.GetPDDoc();
pdDoc.Save(3, @"D:\Bad Files\file1.pdf");
avDoc.Close(1);
catch (Exception ex)
MessageBox.Show("Caught!");
But we seem to have a certain amount of corrupt tif files that occur every now and then which are causing a problem. When the avDoc.Open line runs, there is a popup error message that says.
"Acrobat could not open 'file1.TIF' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded)."
There is no exception thrown, so the program hangs while it waits for someone to click OK on the message. Is there any way to disable this popup so that the program can continue? I'm not bothered about it throwing an exception, because the pdDoc.Save throws one anyway if the file didn't open successfully.
I have seen a conversation on a forum somewhere suggesting that we should not use the CAcroAVDoc class, we should just use "PDDoc.Open" instead, but PDDoc doesn't seem to exist. I tried using CAcroPDDoc but as far as I can see it can only be instantiated by the instance of CAcroAVDoc and it doesn't have any static methods on it.
We are using Adobe Acrobat Professional version 9.
