Before installing Parallels Plesk Panel for Windows systems, make sure that a static IP address is assigned to the server.
Parallels Plesk Panel for Windows can be installed only on NTFS partitions.
In order for your server to support ASP.NET 1.1, FrontPage 2002 Server Extensions, Miva, File Transfer Protocol (FTP) Service, Server Side Includes (SSI), and Active Server Pages (ASP), you need to install these components manually.
In order for your server to support domain performance configuring, you need to enable the QoS Packet Scheduler service.
If you plan to use MS SQL Server support in Parallels Plesk Panel for Windows, the MS SQL Server should be installed and configured to use standard or mixed security mode. If MS SQL Server is not installed, you can select Microsoft SQL Server to be installed with Parallels Plesk Panel for Windows and configured with administrator name 'sa' and random password.
Internet Information Services (IIS) should be preinstalled with World Wide Web (WWW) Service support.
IMPORTANT: We strongly recommend that you install Parallels Plesk Panel for Windows on a clean server; specifically, only above-mentioned operating system components should be installed.

Mail servers:
Antiviruses:
DNS servers:
FTP servers:
Web statistics:
Web scripting:
Web-based administration tools:
Database servers:

We strongly recommend that you refer to the product installation instructions prior to upgrading/installing and operating Parallels Plesk Panel. The installation guide for Parallels Plesk Panel can be accessed at http://www.parallels.com/en/products/plesk/docs/, along with the rest of the user documentation. Parallels Plesk Panel Knowledge Base can be accessed at http://kb.parallels.com.
Before starting installation, back up any valuable data on the server.
To install the Parallels Plesk Panel software on the server:
In order to finish the initial configuration of Parallels Plesk Panel, you need to log in to Parallels Plesk Panel on your server at https://domain.name:8443/ or https://IP-address:8443/
The default username is "admin" and the default password is "setup". The password is case-sensitive. For security reasons, you must set a new password upon initial login.
You also need to obtain and install a license key suitable for Parallels Plesk Panel 9.5.
IMPORTANT: Make sure you upgrade all installed components when upgrading to Parallels Plesk Panel 9.5.1. This is required to avoid conflicts caused by outdated components.
IMPORTANT: If you are upgrading Parallels Plesk Panel on an intensively used hardware node, it is strongly recommended to use the following PVC parameters for the upgrade:
vprvmem (virtual memory) - 700
numproc (number of processes) - 100
After the upgrade is finished, these parameters should be set to their previously used values.
If you have Plesk version earlier than 8.1.x installed, then you need to upgrade it to Plesk 7.6.1 first, migrating all data, upgrade it to Plesk 8.1, and then run the Parallels Plesk Panel 9.5.1 installer. Refer to Plesk 8.1 Release Notes for additional information if you want to upgrade your Sitebuilder shipped with Plesk 7.6.1.
If your machine has Plesk 8.1.x, 8.2.x, 8.3.x, 8.4.x or 8.6.x installed, you will be prompted to upgrade the existing Plesk installation to Parallels Plesk Panel 9.5.1 after running the installer.
Parallels Plesk Panel 9.5.1 for Windows includes Sitebuilder 4.5 in the distribution package, but your Sitebuilder 2.x or 3.x installation will not be upgraded automatically. If you want to upgrade your Sitebuilder version during installation of Parallels Plesk Panel, run the installer executable with the following option:
WSB_UPGRADE=force
If you used Sitebuilder 2.0.5 with earlier versions of Plesk, you can migrate websites created in Sitebuilder 2.0.5 to Sitebuilder 4.5 after you upgrade your Plesk software to Parallels Plesk Panel 9.5.1.
To successfully migrate websites created in Sitebuilder 2.0.5 to Sitebuilder 4.5:
When migrating to version 9.5.1, Migration Manager reports that dump validation failed due to invalid value of the "enabled" attribute of mail redirects for some mail accounts where mail redirection is set up but disabled. This can be resolved by enabling the problem redirects during migration.
Migration task hangs if migrating more objects (for example, domains) than the number allowed by the license.
When installed in a Parallels Virtuozzo Container, the Panel does not work if offline management is enabled (offline_management on). To resolve this issue, turn off the offline management for the Container.
Upgrade fails if some service used by Parallels Plesk Panel is disabled in the Windows operating system.
After installation of Parallels Plesk Panel, the Panel cannot be accessed for up to five minutes. Please wait for five minutes after installation to make sure that all post-installation scripts are finished correctly.
Due to the massive amount of changes in Parallels Plesk Panel 9 GUI, old custom (third-party) skins for Plesk 8.x are not compatible with Parallels Plesk Panel 9.0.0 and later. After you upgrade to Parallels Plesk Panel 9.x, all custom (third-party) skins will become unregistered to avoid visual issues.
Language packs for Plesk 8.x are not compatible with Parallels Plesk Panel 9.0.0 and later.
Before creating a domain through CLI for a reseller or a client, make sure that this reseller or client has at least one free IP address in the IP pool for proper domain creation.

Plesk Firewall works only if Microsoft Windows 2003 Service Pack 1 (or later) is installed.
Virtual directories are not restored by Parallels Plesk Panel backup/restoration functionality.
If you wish to patch Parallels Plesk Panel over the network, you should have write permissions for the Parallels Plesk Panel distribution package files (which are unpacked during Parallels Plesk Panel installation). This notice does not apply to the Web installer.
SmarterStats user is created with the credentials of a corresponding domain FTP user. It should be noted though that SmarterStats user password will contain only alphanumeric characters and '_' symbol used in place of all non-alphanumeric characters.
If an external Sitebuilder system (that is, Sitebuilder installed in SVE or VPS environment or on a remote server) is integrated with your Parallels Plesk Panel server, your customers will not be able to access Sitebuilder through Parallels Plesk Panel if they use Internet Explorer with default security settings. To resolve this issue, make sure that both Parallels Plesk Panel and Sitebuilder are located in one subnet (for example, 110.57.106.1 and 110.57.106.2). Alternatively, you can tell your customers to go through the following procedure:
Open Internet Explorer and go to Tools > Internet Options > Privacy > Sites.
Enter the address of the external Sitebuilder system in the Address of Web Site field and click Allow.
Parallels Plesk Panel does not automatically detect third-party components. After a new third-party component is installed, you need to go to Parallels Plesk Panel > Server Components, and click Refresh.
If you run both Parallels Plesk Panel and Parallels Sitebuilder inside one Parallels Virtuozzo Container, then make sure that you allocated at least 700 megabytes of disk space to this Container.

If VZ MSDE template was installed after remote database servers were set up in Parallels Plesk Panel, working with remote database servers will be forbidden because VZ MSDE template switches the work mode from remote to local. To resolve this issue, you have to manually switch the work mode from local to remote.
SMTP sessions are not blocked by DNSBL if you are using Smartermail Free 5.0, 5.1 or 5.5. To resolve this issue, set up SMTP sessions blocking by DNSBL in the Smartermail mail server settings.
Drwebcom.exe is falsely detected as a virus by AVG, leading to Parallels Plesk Panel installation/upgrade failure.
Parallels Plesk Panel servers using Single-Sign On service (required for integration with Parallels Plesk Billing) will not be accessible if Single-Sign On service stops working for some reason. To access Parallels Plesk Panel in this case, you have to switch off the usage of Single-Sign On by going to %plesk_cli% and running command sso --disable.
You might encounter a warning about ASP.NET being unavailable when installing Parallels Plesk Panel on x64-based operating systems with .NET 2.0 installed beforehand and IIS working in 64-bit mode. This warning can be ignored because Parallels Plesk Panel will resolve this issue automatically.
