Administrator Guide

Use this registry setting for testing/debugging only, as this registry setting controls log verbosity for other components,
including the Encryption client and Encryption Management Agent.
● Compatibility Mode allows applications to run on the client computer while Memory Protection or Memory Protection and
Script Control policies are enabled. Enabling compatibility mode requires adding a registry value on the client computer.
To enable compatibility mode, follow these steps:
1. In the Management Console, disable the Memory Protection Enabled policy. If the Script Control policy is enabled, disable
it.
2. Add the CompatibilityMode registry value.
a. Using the Registry Editor on the client computer, go to HKEY_LOCAL_MACHINE\SOFTWARE\Cylance\Desktop.
b. Right-click Desktop, click Permissions, then take ownership and grant yourself Full Control.
c. Right-click Desktop, then select New > Binary Value.
d. For the name, type CompatibilityMode.
e. Open the registry setting and change the value to 01.
f. Click OK, then close Registry Editor.
To add the registry value with a command, you can use one of the following command line options to run on the client
computer:
○ (For one computer) Psexec:
psexec -s reg add HKEY_LOCAL_MACHINE\SOFTWARE\Cylance\Desktop /v
CompatibilityMode /t REG_BINARY /d 01
○ (For multiple computers) Invoke-Command cmdlet:
$servers = "testComp1","testComp2","textComp3"
$credential = Get-Credential -Credential {UserName}\administrator
Invoke-Command -ComputerName $servers -Credential $credential -ScriptBlock {New-Item
-Path HKCU:\Software\Cylance\Desktop -Name CompatibilityMode -Type REG_BINARY -Value
01}
3. In the Management Console, re-enable the Memory Protection Enabled policy. If the Script Control policy was previously
enabled, re-enable it.
