Report SecSNMP.dll missing

[libraio]

Use PDF Vier with XP Professional SP3.When the press launch I get the following message "unable to start the specified application. SecSNMP.dll has not been found. Re-installing the application may fix this problem ". Of course I already tried to reinstall the program and update continuously, but the message reappears.I close the error message screen, minimizing or close PDF Viewer and appears to me, below, print, preview correctly.You can resolve this issue by this message?Excuse my poor English, I'm Italian.
Thank you!

Hi - sorry to hear you are having problems, however this file is not one we supply or support and is nothing to do with PDF-XChange.

I have googled this file name and there is much info out there on the web and I suggest you do the same - but I assure you it is not PDF-XChange specific or related ...

looks like there is some other issue on your PC that needs some attention ....

Thank you for the prompt response.
The important thing for me is that the dll is not required to request program. Keep and then to use it as is, with the only bother to close the warning screen to start printing.
Greetings
