creating linked clones powershell failed

We are running the following command Powershell vWorkspace 7.5:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -scope CurrentUser

Import-Module Quest.vWorkspace.PowerShellModule

Connect-QVWFarm -Farm "vWorkspace_Database"

Set-QVWProvisioningSettings -ComputerGroup "VDI-vBlock" -CloneMethod VMwareLinkedClones -ParentVM "PRB-GOLD-V-002" -Snapshot "Gold 24-05-12" -Farm "vWorkspace_Database"

$SC_target = (Get-QVWDistributionTarget -ComputerGroup "VDI-vBlock" -farm "vWorkspace_Database")

$Name_conv = (New-QVWNamingConventions -BaseName "maq??" -Increment 1)

Set-QVWProvisioningSettings -ComputerGroup "VDI-vBlock" -DistributionTargets $SC_target -NamingConventions $Name_conv -SysprepCustomizations "sysprep" -farm vWorkspace_Database"

New-QVWComputer -ComputerGroup "VDI-vBlock" -NumberToCreate 1 -farm "vWorkspace_Database"

Linked clones are created, but does not run the sysprep. Another problem is the parameter -folder, it displays an error that does not exist, but the path is correct.

Anyone know why can it happen??

Thanks
