Having upgraded to WPTools7, I also downloaded and installed the latest version of WPDF3 Plus.
I now find that if I create a new blank project with a single form, and drop any of the 3 components from the WPDF palette onto the form, and compile it, Windows 8 immediately denies access to the .exe because "the file contains a virus or potentially unwanted software".
If I delete the component and recompile, all is fine.
