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!
Download and save your ebook.
To read your ebook you will need a free special PDF reader for the PC, Mac, Android or iPAD/iPhone called "Javelin" or "Javelin3". You only need to download and install our PDF reader once, however many ebooks you purchase. The PDF reader is available for the following devices:
Run "Javelin" or "Javelin3", open the file you have saved. Please make sure that you have your Authorization code or codes for the book(s) you have ordered. It will prompt you for your authorization code to open the document.
Please see below for the most common questions we are asked, and how to resolve them:
A: You will need to provide details of your order and authorization code to the publisher, with an explanation of why you need the code reset and they can reset the code for you if they are happy to do this. This problem usually arises for one of the following reasons: (a) you have a new computer/device and need a code for this new device or as a result of a re-installed operating system on an existing device; (b) you used the remove authorization option or deleted the file and its associated data by mistake and need the code re-enabled; (c) you did not download and save your drmz or drmx file to a permanent location (e.g. your Documents folder) before opening it with Javelin for Windows or Javelin for Mac - you will need to have your code reset and to make sure you download and save the file BEFORE opening it.
A: You will need to provide details of your order and authorization code to the publisher, with an explanation of why you need the expiry date reset and they can reset the code expiry date for you if they are happy to do this. This problem usually arises because the code in question was issued 3+ years ago and had an expiry date set for that duration - expiry dates on codes are separate from document expiry.
A: Check that you can access the internet and have a good connection - a good direct or WiFi link is best, or a mobile link of at least G3/H++ or G4 - poorer G2 and G3 links will almost certainly not work. If you have a good connection, check you can access the following link: https://www.drumlinsecurity.co.uk/Service.asmx; if you can connect to this page but cannot register Javelin or authorize the document, ask your IT department to enable messages to/from this web address on your Proxy server/Network gateway OR use a tablet or portable device (e.g. a laptop) to authorize the file offsite (e.g. at home) or via an open WiFi point - once a device is authorized it does not require authorization again so you can take the device into the office, on an aircraft etc. without needing an internet connection. Note that it is the device that is authorized to view the file - the file itself is never altered. Javelin3Pro for Windows can get around such problems using the WEB REGISTRATION and WEB AUTHORIZATION facilities built-into the software or if all else fails, license files, which you would need to ask us about. Another option with Javelin3 or Javelin3pro for Windows is to use the File menu, Proxy settings option (this "may" work if you have access blocked by a commonly used Proxy server but it will depend on the server in question and it may well be that it is a firewall that is stopping access). If you are still stuck contact us for help!
A: Please run Javelin3Pro, select the Tools menu, Registration option and try pressing the WEB REGISTRATION button, and this should enable you to register automatically via a web page. If you cannot press the WEB REGISTRATION button try pressing the UN-REGISTER button first and then re-enter your registration details and use the WEB REGISTRATION button. If you still cannot register please let us know via the EMAIL REGISTRATION button and we will register you manually. Once registered, please try opening the drmz file you were provided with and entering the authorization code you were sent by the publisher. If this results in an error message (e.g. your network prevents access) please check the answer in the previous item above (try sing the WEB AUTHORIZATION option) and if necessary, let us know what the problem seems to be, including the authorization code you were provided with, so we can resolve this for you.
A: If your document will not print it is most likely that it is set to not permit printing. If it does appear to be printable but will still not print then it may be one of several reasons:(i) if you try to print to a device that is not accepted by the software it will either issue a warning message or tell you that it does not recognize that particular printer. If it is the latter, try printing again and then select the File menu, Log file option, and email us your log file; (ii) if you are printing to a device (e.g. a network printer) that is not set to start printing as soon as it receives pages, then the printer may fail because pages are sent as print images and are therefore large, like photos. For this reason solution include: (i) if you print the file in blocks, e.g. of 50 pages or less, then it is far less likely to crash your printer (this is a printer memory issue); (ii) ensure the printer is set to start printing as soon as the first page is sent to it, i.e. not to store the pages and then print them, so that its memory is emptied as it is filled; (iii) print at 300dpi if possible - this will use less memory - Javelin3 and Javelin3Pro (current versions) both have facilities for adjusting the print settings used via the Tools menu; (iv) try printing to a different printer, ideally one locally connected that you can control directly - printing to WiFi connected printers and "software services" like MyPrint will typically not work. Note: Two-sided (double-sided) printing and similar specialized print formats are not supported by Javelin readers.
A: If the Mac has a terminal session running then Javelin3 will close, as a security measure. The solution is simply to close the terminal session on the Mac and it will allow Javelin3 to run.
A: The brief answer is "no", but text-to-speech does work on Mac OSX devices with Javelin3. The Javelin software does not itself support text-to-speech operation and the files cannot be saved or exported to other formats, such as text or standard PDF - in most cases please contact the publisher for assistance as they may be able to offer an alternative file format for special cases such as this.
A: The message appears if the publisher has specified "Disable screen capture" when generating the file AND the end user has a screen capture program running at the time the document is viewed. There are two solutions for the end user: (i) follow the on-screen instructions to close the background process identified in the on-screen message; or (ii) ask the publisher for a copy of the secured file without this option set.
A: For the new Catalina operating system and all recent versions of OSX, you should be running the latest version of Javelin3 for Mac, which you can download for free from our Javelin Downloads page: https://www.drumlinsecurity.com/javelindownloads.html. Javelinm, which is the old version of Javelin for Mac, will not run on Catalina so will issue a message to that affect. Javelinm is designed for OSX 10.6 to 10.9 and most Mac devices no longer run these versions of OSX.
A: Linux/Unix - there is no native reader for Unix variants, but Javelin for Windows and Javelin3 for Windows can be run via a Windows virtualization package, if available.
