When trying to create, import, or delete layers using SWV Admin tool or Virtual composer an error message pops up:
An unexpected error has occurred. Error code 1089
The Windows Events show messages related to the fslx driver:
Code integrity determined that the image hash of a file is not valid. The file could be corrupt due to unauthorized modification or the invalid hash could indicate a potential disk device error.
File Name: \Device\HarddiskVolume2\Windows\System32\drivers\fslx.sys
The fslx.sys driver cannot start. To confirm that fslx.sys is not started open a command prompt as administrator and run:
sc query fslx
The following command normally starts fslx.sys:
sc start fslx
However if the system is missing a specific patch (KB3033929) this message will appear:
[SC] StartService FAILED 577:
Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.
