Request for ZenOn 5.50 SP6 Installer (Following HDD faillure)

[justtalks]

Dear members,
I hope this message finds you well.
Following a recent hard driver failure, i have unfortunately lost access to the installation files for ZenOn 5.50 SP6, which is required to support and maintain an existing SCADA system in our facility.
If anyone could kindly assist by providing a legitimate download link, or point me toward an official source where i can obtain this specific version, i would be sincerely grateful.
Please note that i do have a valid licence for this version.
Thank you very much in advance for your time and support.
