Post-Sync scripts stopped working after upgrading to Horizon 7.12
After upgrading to Horizon 7.12, our Post-synchronization scripts stopped working, and pools would ERROR out when provisioning instant clones.
Turns out, its a bug in Horizon 7.12. I saw a few of you with the same issue in the following thread, but I’m starting a new post for better visibility since it was off-topic.
The bug is that the Horizon agent copies the script to c:windowstempvmware folder…but fails to copy it successfully.
The DEBUG log shows the FAILED Creating Post-Customization, Hash File: 0x80070003 error.
If you manually pre-copy the actual script file into the c:windowstempvmware folder before creating your snapshot, it will work as intended.
I’ve opened a Support Case with VMware and will post the solution once I get it.
