Desktop PreVeil Version 6.0.5 (Windows)
Release date: June 17, 2026
PreVeil Desktop 6.0.5 for Windows includes security improvements, Drive reliability fixes, and several Admin Console and email enhancements.
Security
Unquoted service path vulnerability resolved
Addressed a long-standing security issue where Windows registry service paths installed by PreVeil were not properly quoted. Unquoted paths containing spaces can be flagged as a privilege escalation vulnerability by security scanning tools. Service paths are now correctly quoted on installation.
What's improved
Drive & file handling
Fixed an issue where renaming a file or folder could fail silently if the server acknowledged the rename but the client never received the notification, leaving the item with its old name.
Fixed a crash that could occur when Cloud Drive received empty data blocks during a sync operation.
Resolved an issue where the hydration job queue could become blocked after reaching 1,024 queued jobs, preventing further files from being downloaded.
Addressed an issue where users with stale or locked directory keys could be unable to access a shared folder, resulting in an "Invalid directory key" error. This could occur following account recovery, key rotation, or re-addition to a shared collection.
Corrected an error message that displayed "unsuccessful" instead of "access denied" when a user attempted to delete a read-only shared folder.
Fixed a behavior where right-clicking a folder and selecting Share did not open the Share dialog.
Admin Console
Added a Select All / Deselect All option for the user selection screen in Data Export, and corrected an issue where deleted accounts were incorrectly included in the user count.
Fixed an issue where deleting a draft reply could cause the original email to be lost.
