The Windows agent App Control engineering team has uncovered an issue for customers on Windows Server 2008 Service Pack 2 where upgrading to or installing any Windows Agent Versions after 8.6.0 will not work as intended.
We are advising customers planning to install or upgrade their Windows Agent on Windows Server 2008 SP2 not to use 8.6.2, 8.7.0, or 8.7.2. Customers on Server 2008 R2 are not affected by this issue.
We are working on a resolution to this issue and will update this post when we have more information.
