Error - Failed to parse response - when opening Backup Manager - 12.0.18

New Pleskian
Hello, I have upgraded my PLESK installation to latest 12.0.18 (updates from today) on Windows Web Server 2008 R2 (Latest Updates).

maybe last autobackup task has failed due empty disk space

Now I get the following error-message when opening Backup-Manager

Code:
Message:Failed to parse response. Reason: Failed to read data from stream Process output:
File: 	PMMConnector.php
Line: 	708
Type: 	PleskPMMResponseException

I'm not sure whether the update or the backup task caused the error

The Reconfigurator also brought no success.

The auto installer will also not find any other updates.

Can anyone help?

Sorry for my bad English.
Kind Regards

No python.msi insaller in C:\ParallelsInstaller\parallels\PANEL-WIN_<plesk_version>\thirdparty-msi-Windows-any-x86_64 folder

But a python-conf.msi and plesk-python.msi in
C:\ParallelsInstaller\parallels\PANEL-WIN_<plesk_version>\dist-msi-Microsoft-2003-i386

should i execute one of these?

Entering "pmmcli --help" gives the following output

It is python errors. I suggest you reinstall python on this server.
 
Found python.msi on other machine and copy it to destination machine (Same OS and PLESK Editions)
First I run repair and then reboot machine, nothing changed
Then I try remove and reboot then install and reboot, but same error message

Install path is "C:\Program Files (x86)\Parallels\Plesk\Additional\Python\"

Problem solved,

in folder "C:\Program Files (x86)\Parallels\Plesk\admin\share" was an empty folder named "migration-handler" of unknown origin.

I deleted it, this has fixed the problem directly and without reboot.

Thanks for your helpful support, you showed me the way :)
