Encrypt PDF not a valid win32 app


Hi there,

Remember that win32 application validation greatly depends on downloading source and packages, if your downloaded file is corrupt and not properly extracted it will give an error in validation of an application!

Go to this link to download proper and complete package for Encrypt PDF and make your way easier, "http://dl.verypdf.net/encryptpdf_cmd.zip"


Don't forget to completely remove previous installed encrypt PDF and remove it completely from your system, then download using this link and install, then reboot your system and try encryption again!

Hope it works for you!
