Issue Cannot update plesk because of files removed by antivirus

[treenet]

Server operating system version

Windows 2022

Plesk version and microupdate number

18.0.61 Update #6

Hello,
i'm looking for advices and other's experiences.

Scenario:
Hosted VPS with Plesk license offered by hosting provider - Win 2022 with running Plesk Version 18.0.61 Update #6 - kaspersky antivirus - firewall ports for plesk updates are open - provider is not able to help and suggest to reinstall or migrate.

Problem:
Plesk is running but updates keep failing and autoinstaller3.log shows some errors:
"GetProductsList() ERROR: Bad configuration was detected for product with Product code: {B81911AA-E961-3F44-691F-AAA2C6F017FD} (Upgrade code: ). MsiGetProductInfo() return code: 1608."
"GetProductsList() ERROR: Bad configuration was detected for product with Product code: {E3B93DAC-525F-2264-DB7D-89C90793A3EB} (Upgrade code: ). MsiGetProductInfo() return code: 1608."
So i think some installers files are missing in the install directory and prevent updates to install.

What i tried - (not solved):
Plesk Reconfigurator and Plesk-repair-kit didn't help.
I tried to restore files from backups but the problem has appeared time before the date of the first available backup set, and files are not available in the backup.
I'm pretty sure that Kaspersky deleted some files but i can't find them in antivirus console backup or quarantine (it happened again a couple years ago, but that time a was able to recover them). I remember that C:\Program Files (x86)\Plesk\admin\bin\ai.exe and other files were removed by antivirus, but i don't have a complete list to compare.

What i'd like to ask to community:
If possible, i'd like to keep the server running and minimize downtime needed for a complete migration or recovery.
Is there a simple/fast way to reinstall the same Plesk version or replace some folders from an official repository (ftp) without having to recover from a backup?
Is there a simple way to look/compare for missing files? I don't have other servers with this version installed.
Is it possible to uninstall bad MSI files (something like "msiexec /x {B81911AA-E961-3F44-691F-AAA2C6F017FD} /qn" ) without breaking Plesk and then start Plesk updater?

Thank you,
Angelo

Hello, Angelo. As far as I can see, this error results from corruption in the MSI subsystem:

MsiGetProductInfo failed to retrieve ProductVersion while installalling SQL

Fix MsiGetProductInfo failed to retrieve ProductVersion for package with Product Code = ‘{GUID}’. Error code: 1605/1608 while installing SQL in Windows.

If contacting Microsoft to fix the subsystem is not an option, what you can consider trying is restoring the server if you have a snapshot from a healthy point (that might not completely solve the issue), try disaster recovery, or a migration to a brand new server. What else you can try is manually moving the configuration file from a healthy environment, but that should be performed with caution and at own risk.
