Our Javelin PDF readers for desktops, laptops and mobile devices are very fast, small, secure and fully-functional PDF readers. To download the free Javelin PDF reader simply click on the link provided below for your computer or mobile device. The Windows version is provided as an installation program - run this by double-clicking the file, ignore any warning messages, and follow the on-screen instructions. When finished Javelin will be available ready for use, and a link to Javelin will be added to your Desktop for future use.

Having downloaded the Javelin reader for PC or Mac, simply run Javelin and select the File menu, Open option, to open and read a standard PDF file or a secured PDF file (a DRMZ or DRMX file). DRMZ and DRMX files will prompt you for an authorization code - copy the code you have been sent by email and paste it into the field. Press OK and wait for this to be checked over the internet. The file will then be displayed. You only need to do this the first time you access the file. Mobile versions of Javelin include test files built-in to the app.

All our software products have been checked to ensure they are virus free. Norton Antivirus users - if your antivirus software will not accept a download from us or deletes it/places it in quarantine, we are certain that this is a false positive. Please report this to Symantec as an error. To resolve this please either turn off the offending behaviour in Norton's software (Insight and/or SONAR) or recover the quarantined file from within Norton Antivirus, or use another antivirus product like AVG!
