with the PBA active. [DDPC-2684]
Technical Advisories v8.7
Enterprise Edition for Windows
● If the HCA algorithm is changed during encryption, SDE encryption rather than HCA re-encryption begins. To work around
this issue, restart the computer. After log in, HCA encryption begins normally. [DDPMTR-406]
● Reinstallation may fail with an error such as a file or folder access error or an EMSService crash, if the \temp folder was
previously encrypted with the Common Encryption Key and files were not fully decrypted before uninstallation. To work
around this issue, before reinstalling, remove files from the \temp folder. [DDPMTR-1647, DDPMTR-1782]
● When the Encryption Removal Agent is used to decrypt and uninstall, if an invalid Encryption Administrator Password is
entered, an incorrect error message displays: "Failed to deserialize the specific file" [DDPMTR-1649]
● Running Diagnostic Info results in a file archiving error if run when files that must be accessed are locked or in use.
[DDPMTR-1830]
● When running the Setup Wizard after WSDeactivate, access to Common and User encrypted data is lost. To work around
this issue, after running WSDeactivate, do not run the Setup Wizard. Instead, perform File/Folder Encryption recovery as
explained in the Recovery Guide. Select the option, My system does not allow me to access encrypted data.... Reboot the
computer then run the Setup Wizard to re-activate the user. [DDPMTR-1831]
● When the EMS Access Code Failure Action policy is set to Apply Cooldown, the cooldown is not applied. To work
around this issue, after the allowed number of password attempts, the user must manually authenticate to the device.
For more information, see "EMS Authentication Failure" in AdminHelp, accessible from the Remote Management Console.
[DDPMTR-1859]
● If EMS Service (without the full version of the Shield) is installed, uninstall it prior to installing Enterprise Edition. Otherwise,
installation will fail. [DDPMTR-1871]
● Cloud Edition is not supported with the GPO "System cryptography: Use FIPS compliant algorithms for encryption, hashing,
and signing." Set this GPO to Disabled or Not Defined. [DDPCE-1947]
Advanced Authentication
● After upgrade from v8.2 or later, authentication with fingerprints fails. To work around this issue, re-enroll fingerprints after
upgrade. [CSF-746]
● After uninstallation, the DDP Console icon remains on the desktop. To work around this issue, delete the icon after
uninstallation. [DDPMTR-1815]
Preboot Authentication
● If activation fails with an error message that the SED must be recovered, perform a recovery using the instructions in the
Recovery Guide, then reinstall Advanced Authentication and re-activate. [DDPLP-305]
Cloud Edition
● With Google Drive, copying files to the DDP|CE virtual drive results in a warning that properties will be stripped from the file.
Security attributes are removed from the file. No data is lost. [DDPCE-1406]
● Files cannot be downloaded directly from a cloud storage provider's website. To work around this issue, open files in the
DDP|CE virtual drive on the client computer. [DDPCE-1511]
● When an external (non-domain) user creates a text document in the DDP|CE virtual drive, an extra file named "New Text
Document.txt" is created and encrypted along with the user-created file. The extra file can be deleted. [DDPCE-1608]
