Installation error

[leo_biker]

Hello.
I have the same error like in this topic
I have downloaded com_abook_4_0_1.zip from this page
So arhive must be ok.
What is the reason can be?
Also it's impossible to install it from JED.
Thank you!

Hi leo_biker,
"Could not find XML file to install package" means the installation xml file is not readable or corrupted after unzip process.
I suggest to unzip the installation package in a folder in your local device (eg: /abook_installation) then copy that folder to the /tmp folder of you web site (eg: website/tmp/abook_installation).
At this point you can try to install Abook using "Install from folder" tab (see https://docs.joomla.org/images/d/d9/Help-4x-Extensions-Manager-Install-InstallfromFolder-screen-en.png).

Seens problem was in virtual hosting.
I have installed it locally and have no any problems during installation.

I have some problems, when i try to add books or authors.
Am i need to create new topics?
When i try to add new authors i have this

When i try to add new books i have this
PHP Deprecated:  Required parameter $directory follows optional parameter $active in C:\inetpub\wwwroot\administrator\components\com_abook\helpers\files.php on line 25
