Activation of Adobe Photoshop
®
 and Other Products Using FLEXnet Publisher
®
 / SafeCast 
Note: The issue described below does not affect you if you use TrueCrypt 5.1 or later and a non-
cascade encryption algorithm (i.e., AES, Serpent, or Twofish).
*
 The issue also does not affect you 
if you do not use pre-boot authentication (see the chapter System Encryption). 
Acresso FLEXnet Publisher activation software, formerly Macrovision SafeCast, (used for 
activation of third-party software, such as Adobe Photoshop) writes data to the first drive track. If 
this happens when your system partition/drive is encrypted by TrueCrypt, a portion of the 
TrueCrypt Boot Loader will be damaged and you will not be able to start Windows. In that case, 
please use your TrueCrypt Rescue Disk to regain access to your system. There are two ways to do 
so:
1. You may keep the third-party software activated but you will need to boot your system from 
the TrueCrypt Rescue Disk CD/DVD every time. Just insert your Rescue Disk into your 
CD/DVD drive and then enter your password in the Rescue Disk screen. 
2. If you do not want to boot your system from the TrueCrypt Rescue Disk CD/DVD every 
time, you can restore the TrueCrypt Boot Loader on the system drive. To do so, in the 
Rescue Disk screen, select Repair Options > Restore TrueCrypt Boot Loader. However, 
note that this will deactivate the third-party software.
For information on how to use your TrueCrypt Rescue Disk, please see the chapter TrueCrypt 
Rescue Disk.
