Caution! If all your license-keys were issued before 2nd September 2006, then this version of PDFing will only work in "un-licensed" mode. Please do not proceed with installation unless you have a license-key issued on or after 2nd September 2006. If you have not yet done so, you should apply your support/upgrade license-key as soon as the installation is complete. If you have not purchased a PDFing license-key since this date, you may renew your support contract in order to receive an upgrade license-key which will allow V4 to run fully licensed, without limitations.

Regrettably, some of our customers running version 1 and using the more advanced features may need to adjust to their markup files. Please check if any of these changes to features apply to you!

Before you install PDFing version 4, you must first stop PDFing. If you are running PDFing as an NT Service program, then you must use the windows administrative tools applet: "Services" to stop the PDFingMailer service.

Before you install PDFing version 4 over an existing v4 installation, please note the directory in which your existing copy of PDFing is installed. When you run the "windows installer file" PDFing4setup.msi and the "Select Installation Folder" dialog appears, select the name of the previous installation directory, as noted above. Providing that you install PDFing v4 into this same directory then you will not need to re-configure PDFing. If you install version 4 into a different directory, then you should follow the steps listed in the following section.

In some circumstances, the "windows installer" will ask if you want to remove the existing copy of PDFing. If so, you should select the remove option, and you will then be prompted to remove the configuration and queue directories. When prompted, you should not enter Y or y, unless you are sure that you will not be re-installing PDFing, or you have a backup of your existing \PDFing\Markup directory. After you have removed the existing copy of PDFing v4, run PDFing4setup.msi again.

Before you install PDFing version 4 over an existing v3 or v3.1 installation, please note the directory in which your existing copy of PDFing is installed and then use the windows control-panel applet: "Add or Remove Programs" to locate PDFing and remove its program files. After you have removed the previous version of PDFing, its configuration and markup files will remain intact within its installation directory. Then run the "windows installer file" PDFing4setup.msi and, when prompted for the name of the installation directory, select the name of the previous installation directory, as noted above. Providing that you install PDFing v4 into this same directory then you will not need to re-configure PDFing. If you install PDFing v4 into a different directory, then you should copy the saved configuration files for re-use in PDFing v4.

Before you install PDFing version 4 over an existing v1 or v2.1 installation, please make a copy of the PDFing program files before deleting them, or rename the directory containing the PDFing program files before installing V4. When you have saved the existing program files, run the "windows installer file" PDFing4setup.msi. After PDFing v4 is installed you should copy these saved configuration files for re-use in PDFing v4.

If you installed version 4 into a different directory and you have saved your existing configuration files, you should select menu-option [File|Markup] to display the file-open dialog-box, select files of type - all files, then take the following steps:

• Copy the saved file: \PDFing\PDFing.ini (if it exists) and paste it into the list of files in this dialog box.

• Copy all the files in the saved directory: \PDFing\Markup and paste them all into the list of files in this dialog box.

• Copy the saved file \PDFing\Res\Ebcdic.txt (if it exists) and paste it into the list of files in this dialog box.

• Close the dialog box.

• Once you have confirmed that these files have been copied to the correct location, you may delete all the saved program files and directories.

If you installed version 4 into a different directory, and you were running PDFing as an NT Service program, you will need to un-install the previous version and then install the existing NT service program for PDFing.

You may also need to change the target and start-in values of shortcuts on the desktop or start menu that were not created by the PDFing windows installer file.
