Prey unattended install for computers
Before We Start
Download the latest Prey installers for laptops from our GitHub releases page (MSI for Windows included). You can ignore this if you're installing into mobiles, or check our article about mass deployment on phones.
You can find your API Key on your account settings, white over blue at the bottom-left corner of the screen.
There are two different installation methods for Windows, an
EXE and an
MSI installers. Both will work and install Prey on your systems, with two main differences.
MSIpackage is completely silent. There won't be any user dialog when installing. Any error will break the installation, and the output be written into a log file. No uninstaller file will be created.
EXEpackage requires a few clicks, will create an uninstaller, and will remove any previous Prey installation.
Run the command prompt as an admin, and run the following command on it:
msiexec.exe /i prey-windows-1.X.X-xxx.msi /lv installer.log /q AGREETOLICENSE=yes API_KEY=foobar123
Which should look like this:
If you need a confirmation message at the end of the process, you can change the
/q parameter to
/qn+. Otherwise it will be silent.
This method will fail on computers without an internet connection. In order to disable the immediate validation against the Prey servers just add the
SKIP_VALIDATION=yes parameter. In that case, the command would look like this:
msiexec.exe /i prey-windows-1.X.X-xxx.msi /lv installer.log /qn+ AGREETOLICENSE=yes API_KEY=foobar123 SKIP_VALIDATION=yes
EXE installer is more oriented to individual users, not to organizations. It will require a few clicks even on its most silent mode, and will create an uninstaller in case you need it in the future. To get an unattended install of the
EXE file run the command prompt as an admin and run:
prey-windows-1.X.X-xxx.exe /S /API_KEY=foobar123
The command should gracefully look like this:
/S parameter makes the installation silent, though it can't be completely silent. For that please prefer the MSI method.
Mac OS X
Open a terminal and run the following command:
API_KEY=foobar123 sudo -E installer -pkg prey-mac-1.X.X-xxx.pkg -target /
Important: You must pass a valid API_KEY value or the process won't work.
The script will actually check if the key is valid and if the account has available slots before copying anything to disk. This means that if the
API_KEY verification fails, the install process will exit with a fatal error and it won't copy anything.
Ubuntu and Debian-based Distributions
Run the following commands on a terminal:
sudo apt-get update API_KEY=foobar123 sudo -E dpkg -i prey_1.X.X_amd64.deb
In case dependencies aren't found, just run these two additional commands:
sudo apt-get -f install API_KEY=foobar123 sudo -E dpkg -i prey_1.X.X_amd64.deb
npm install -g prey # this will make the 'prey' command available system-wide sudo prey hooks post_install sudo prey config account authorize -a foobar123 # foobar123 is your API key<br>
To image deploy Prey on your computers is simple. Steps must be followed entirely, though, or bad things might happen. The most important part is that Prey must be the last app to be installed on the master machine. You can't connect it to the internet after this process or you'll get cloned machines on your Prey account.
Once you're done with everything else and you are ready to setup Prey,
- Install the regular Prey package on the master machine, double clicking on the installer.
- When the process finishes just close the config dialog. Do not enter your account's credentials. We can't insist enough on this.
- Disconnect from the internet.
- Edit the
prey.conffile and add your API Key to line 36. The location of the file is:
- Mac OS X & Linux:
- Save changes.
Do not connect to the internet.
Now you can deploy the image into other computers. As soon as the new devices connect to the internet they'll be added to your Prey account.
Troubleshooting and Known Issues
Cloned Devices From an Unattended Install
Device registration is based on hardware. Sometimes manufacturers don't assign a serial number to all computers they sell, and it ends up being "To Be Filled by O.E.M." In this case, Prey won't be able to tell that those are separate devices, and they will share the same
device key. That means that a single device entry on your Prey account will manage several computers, the one sharing hardware information.
To prevent this from happening you can disable the "Overwrite devices if their hardware information already exists on this account" option from the Device Management settings and install Prey again. Unfortunately this is only available for accounts with 100 or more device slots. If this affects you, please contact us to get it fixed.
Cloned Devices From Image Deployment
If the previous case doesn't fix the problem, then it means that you connected the master machine to the internet after installing Prey. That made it create the device on your Prey account, and then it cloned that same configuration to all other computers. To fix that, completely uninstall Prey and start again.
