What's Acrobat version? What's Windows version? What class from wwPDF are you using?
Check registry key HKEY_CURRENT_USER\Software\Adobe\Acrobat PDFWriter. You should see value named bExecViewer with value data 0. If it's 1, change it to 0.

>Hi,
>
>I tried Free Class from WW called WWPDF. Only problem I seen with this is it prints to a temporary post script file, copies to file where we desire (Sent as parameter) and erases temporary file.
>
>Now Problem is after printing to temp file, Acrobat tries to open that PDF and could not locate the file.
>
>What I need is a silent printing to PDF, that is Acrobat should not pop-up with File. I set off setting "View PDF after printing" in Printer preferences, but it still comes up. What is method to prevent Acrobat from opening up after a print is done.
>
>Thanks in advance.
