<title>VeraCrypt - Free Open source disk encryption with strong security for the Paranoid</title>
|
|
<meta name="description" content="VeraCrypt is free open-source disk encryption software for Windows, Mac OS X and Linux. In case an attacker forces you to reveal the password, VeraCrypt provides plausible deniability. In contrast to file encryption, data encryption performed by VeraCrypt is real-time (on-the-fly), automatic, transparent, needs very little memory, and does not involve temporary unencrypted files."/>

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 VeraCrypt,
|
|
a portion of the VeraCrypt Boot Loader will be damaged and you will not be able to start Windows. In that case, please use your
|
|
<a href="VeraCrypt%20Rescue%20Disk.html" style="text-align:left; color:#0080c0; text-decoration:none.html">
|
|
VeraCrypt Rescue Disk</a> to regain access to your system. There are two ways to do so:</div>

<ol style="text-align:left; margin-top:18px; margin-bottom:19px; padding-top:0px; padding-bottom:0px">
|
|
<li style="text-align:left; margin-top:0px; margin-bottom:0px; padding-top:0px; padding-bottom:0px">
|
|
You may keep the third-party software activated but you will need to boot your system from the VeraCrypt Rescue Disk CD/DVD
|
|
<em style="text-align:left">every time</em>. Just insert your Rescue Disk into your CD/DVD drive and then enter your password in the Rescue Disk screen.
|
|
</li><li style="text-align:left; margin-top:0px; margin-bottom:0px; padding-top:0px; padding-bottom:0px">
|
|
If you do not want to boot your system from the VeraCrypt Rescue Disk CD/DVD every time, you can restore the VeraCrypt Boot Loader on the system drive. To do so, in the Rescue Disk screen, select
|
|
<em style="text-align:left">Repair Options</em> > <em style="text-align:left">
|
|
Restore VeraCrypt Boot Loader</em>. However, note that this will deactivate the third-party software.
