- Navigate to Users > Pulse Secure Client > Components
- Select the option for Enable minimum client version enforcement, then specify the minimum version in the field provided in the following format:
MajorRelease.MinorRelease.Revision#.Build#
Example:
5.3.1.311
Note: The minimum client version entered in the field provided must match the active package on the device or users will not be able to upgrade Pulse and will not be able to connect.
For Pulse Desktop Client 5.3 and above:
If the minimum version is higher, then end user will be prompted to Upgrade or Disconnect and the corresponding action is taken when selected.

With Pulse Desktop Client 5.2RX:
If the minimum version is 5.3 or above, then the Setup Client will be upgraded to the version that matches the Pulse Desktop Client version being enforced and once connected displays a warning that "A Required Pulse upgrade must be installed or the current session will be disconnected."

Once the user clicks "OK" they are presented with the software upgrade notification and can accept the upgrade by clicking Upgrade or Cancel.

Note: If the upgrade is not triggered within 7 minutes, then the session is automatically disconnected. Therefore, if the user selects "Cancel" and the upgrade is not triggered then the VPN tunnel will remain connected for 7 minutes and then the user will be disconnected. The user will need to reconnect and accept the upgrade to stay connected.
With Pulse Desktop 5.1 and lower:
If the Windows or Mac user has Pulse desktop 5.1 or lower installed, then the minimum client version enforcement feature will have no effect and an alternate method of compliance should be used, such as Host Checker.
Important Consideration: Although Pulse 5.2 is supported for this feature, the upgrade prompt presented to Pulse 5.2 users relies on the already built-in messaging for this Pulse release and gives the end-user the option to choose "Cancel" when prompted which will disconnect their session after 7 minutes of use. To avoid end-user confusion it is recommended to deploy Pulse 5.3 with this feature as the upgrade prompt in 5.3 is updated and provides the user with the option to "Upgrade" or "Disconnect".
Changes in PCS 9.0R1 to MCV functionality
From PCS 9.0R1 the MCV feature blocks Pulse clients with a lower version from connecting and they will not be presented with the option to upgrade. This is described in the
9.0R1 PCS, PPS and PDC What's New Document as:
Minimum Client Version Enforcement - Server side.
• This release adds enhancements to minimum client version enforcement to handle older clients, and to prevent the tunnel from being established at all if the client version is below the minimum specified. This addresses shortcomings in the earlier implementation where clients could get access for a brief windo
w Users can use a browser to access the gateway and upgrade Pulse otherwise to allow Pulse clients to directly upgrade via the gateway the admin would need to disable MCV so users get the upgrade prompt. Please refer to the section
Manage Pulse Secure Client Versions of the 9.0 or later Admin Guides for more information.
Changes in PCS 9.1R14 to MCV functionality
From PCS 9.1R14 the MCV feature gives the option to (force) upgrade the Pulse client to the version specified under the minimum version on the appliance. Administrators need to enable the "Force upgrade Pulse Desktop" option to enforce upgrade.

Users will see the below message once they connect to the VPN with any version lower than the specified minimum client version.

Note: Upgrade is forced (automatic) only with Pulse client version 9.1R11.3 and above.
