Gracias, se solucionó el problema!
Thank you for the fix!
Problem solved.
Not great news - this bug still isn't fixed and now I'm seeing the same basic error when attempting installation from the command prompt!
Was bad, now worse - get it fixed Plesk!
And this happen again in 3.27.0.
I'm currently on 18.0.26 and also get this error. I am not used using commands and while 'proceed with updating Plesk Obsidian to the latest update using the on-screen instructions' i'm wondering if it is normal if i choose install latest available product and then get 57 items which need to be installed? I'm currently on 18.0.26 trying to update to 18.0.27 on windows server 2016
Hello Joost Meij
Yes, it's ok, feel free t proceed.
The resolution worked perfectly for us.
It cannot be right, it installs MSSQL 2012, 2014, php5.0, 5.3, 5.4 and all the range, mylittleadnmin, kasperski, etc., ... aaaahh!
What has that to do with Plesk??
Don't work for me and same error in console update RDP, have actual ver WIN 18.0.26 and want update to 18.0.28.

Hello
@Franco Prati
Together with Plesk 3rd-party components required for webhosting are installed. The amount of components may be set before the installation.

Please, let me know have you applied the workaround? It's expected that the issue occurred for 18.0.26.
Hello
Ivan Postnikov
Yes, do the alternate solution but it also gave the error, impossible update to 18.0.28 from 18.0.26 Windows Server 2012, thanks.
Hi Gabriel Medinas,
Are you probably using a custom source (mirror)?
