## Cause

An uninstall was initiated prior to the upgrade attempt.  

After decryption of an Endpoint Security Client, the client must be uninstalled completely, in order to reinstall/upgrade FDE.

To check if a decryption was performed, look for the message below in *C:\\ProgramData\\CheckPoint\\Endpoint Security\\Full Disk Encryption\\dlog1.txt*:

*FDE_srv.exe:568 StateMachine ------====== ACTION RESULT ======------*

*FDE_srv.exe:568 StateMachine \* Phase: UninstallFDE_srv.exe:568 StateMachine \* Action: Wait for Decryption to finish*
