When I'm trying to use the application, I receive a "DVPAPI is required for Iolo-Antivirus to operate properly" message. What can I do?
In order to fix the missing file issue, I suggest you to reinstall the application. To obtain an official link to download the application, you can visit Software Informer review page of the product. Press the green Download button, save the file to your computer and install it using the serial key received when you purchased the software. If this doesn't help, try to get in touch with iolo Customer Care.
