1. What is the "FileOpen plug-in"?

A plug-in is software that adds an additional function to a software program - in this case, the "FileOpen" plug-in is added to Adobe Reader or Adobe Acrobat so that copyright protected PDF documents can be opened.

The plug-in does not access any data on your computer, but only reads information on usage rights and the encryption mechanism for the document you have ordered.
Further information can be found on the Internet, for instance at the FileOpen Systems site www.fileopen.com


2. The document won't open, but there is no error message. What can I do?

First make sure you have installed the FileOpen plug-in by checking the directory "C:\Programs\Adobe\Acrobat 6.0\Acrobat\plug_ins". If FileOpen is installed, there will be a folder "WebPublisher". If this folder is not there, the FileOpen plug-in is NOT installed. To install it, follow these instructions.


3. I have installed the FileOpen plug-in, but lost data while transferring a document/book.

First, when you download a DRM document, it is locked to the computer used to open it for the first time. If you have lost data during the file transfer you will have to re-install FileOpen and download the file again, as follows:

delete the WebPublisher directory from C:\
install the FileOpen plug-in again (see question 2 above)
download the document again

Important! Do not use another computer when you download the item again. Once you download a document or book, it is locked and encrypted to the computer you used, and our server will not accept downloads to another computer.

4. When I try to open a protected document the program starts the installation process. Why?

Whenever a DRM-protected text is opened, Adobe checks to see if the plug-in is installed. If not, Adobe will automatically try to install it. The only way to prevent this is to install FileOpen yourself.


5. Our company has strict Internet security measures and users are not allowed to install programs themselves. What should I do?

Contact your IT support team.
When the FileOpen plug-in is installed, the file "FileOpen.api" is added to your Adobe Acrobat or Adobe Reader directory - thus you will have to be able to add files to this directory.
In many companies there is a standard plug-in directory structure on individual PCs that allows plug-ins to be distributed automatically. One possible name for this directory is "C:\Programs\Adobe\Acrobat 6.0\Acrobat\plug_ins".


6. Could there be problems with our company's proxy server?

There should be no problems with your company's proxy server.
However, the following information is important:
The FileOpen plug-in connects to our servers via https port 443 and identifies itself to the firewall/proxy server as Adobe Acrobat.
Our servers have the following IP addresses:
193.16.173.74
193.16.173.91
193.16.173.94
193.16.173.95


7. Can I use the plug-in if I have a firewall?

Adobe tries to access the Internet via Internet Explorer's API (application programming interface), even if you are using a different browser, such as Firefox. If the firewall settings do not allow Adobe to use the API, the DRM-protected documents cannot be accessed. In this case, the firewall settings need to be modified accordingly, depending on the firewall software you use.
The FileOpen plug-in connects to our servers via https port 443 and identifies itself to the firewall/proxy server as Adobe Acrobat.


8. Can I use the plug-in with my anti-virus software?

When you open the document, Adobe temporarily saves the file in the Internet Explorer cache. If this is not allowed by your anti-virus software, Adobe cannot open the document.
The information described under question 6 for firewalls applies to anti-virus software by analogy.


9. How do I find out which version of the plug-in I have?

In Adobe Reader or Adobe Acrobat go to the Help menu, click on and select - a window will open, showing you the FileOpen version installed on your computer.


10. Do you support Linux systems?

No.


11. Do you support Macintosh systems?

Yes and no. This online service was not designed for use with the Mac OS nor has it been tested for Mac use.

Our FileOpen partner offers a Mac version of the plug-in on its download page.
Follow the installation instructions given on this page.
