===== Install Windows software =====

Software we will install on Windows virtual machine will show up **on all Client PCs** of the laboratory and can be used **by all users**. So we maintain **one Windows installation** for many workstations. 

==== With installation file ====

We should not execute setup files from our personal network folder **X:\** (My Documents) or directly from a usb stick, **installation may fail this way**.
Instead we create a **temp** folder on **C:\**, copy setup there and **execute from C:\temp**. After installation we delete setup file. Keep in mind also, that we have a storage limit on our personal folder **X:\** (My Documents) so downloading a big file should be saved directly on **C:\temp**.


Installing specific applications like **MSOffice** while connected with our network personal user with administrator rights **may fail**. To solve this we connect as a local administrator **.\Administrator** or **.\root** and retry installation

==== Without installation file ====

In case there is no installation file and we only need to do a **simple copy** to install and we need also to **create a link in the desktop** of all users, we do the following : 
  * We copy the program folder e.g. **newprogram** inside the folder **C:\opt** (we create if it doesn't exist)

==== Create a desktop shortcut for all users ====
If we have installed without an installation file or from an installation file but no shortcuts to the desktop were created we do the following:
  * We login as **local administrator .\Administrator** or .\root
  * We enter the folder where the program was installed and drag the executable to our desktop to create a shortcut.
  * From My Computer we enter C: folder.
  * We click on addrees and type manually C:\Users\Public\Desktop and press ENTER to see folder contents
  * We copy the shortcutwe have created previously from our Desktop to folder C:\Users\Public\Desktop.

==== Getting the application ====

=== Download from Internet ===

This installation is applicable while
  *remotely connected through VNC console **from internet**
  *connected **from a client PC** on local network
  *connected through VNC console **from server PC**.

This is the easiest way to install. We do the following. We **download the installation file from the Internet** and save to folder C:\\temp. Then proceed with the installation.

=== with a usb stick ===

This installation is applicable while
  *connected **from a client PC** on local network

We do the following
  * We insert a usb stick on a client PC on local network
  * We connect to this PC with our network personal user with administrator rights.
  * On Windows file manager it will show up as a device folder **usb_disk στον ltsp** 

<note>On this Client PC that booted from network, **we should not be simultaneously connected to Linux OS as well**, because it will lock the usb drive and we will not be able to see it on Windows. We disconnect from Linux OS to be able to use the usb stick on Windows.</note>

=== with a cdrom/dvd ===
<note>For simplicity reasons we can copy installation files to a usb stick and follow usb installation instructions, avoiding installation from cd/dvd medium</note> 

This installation is applicable while
  *connected **from a client PC** on local network
  *connected through VNC console **from server PC**.


Installation from cdrom/dvd can be done with 2 ways
  - From a Client PC the same way as if we installed from a usb stick.
  - Through VNC console **from server PC**.
    - We insert the cdrom/dvd on **Server PC**
    - [[en:software:lserver-admin:quickstart:connect2server|We connect to Server PC to proxmox from a browser]]
    - On the left pane we select **Datacenter** and double click on **hosta**. 
    - We select Windows virtual machine and click on **Hardware** tab.
    - We select **CD/DVD drive** and press **Edit**
    - We select **Use physical CD/DVD Drive**
    - We connect to Windows with our personal account with administration rights from any **Client PC that has booted from network** or [[en:software:lserver-admin:quickstart:connect2windowsvm|from firefox through VNC Console]]
    - We can now **access cdrom from file manager** and install.
    - After we finish installation, **we restore** the CD/DVD drive from the virtual machine settings to option **Do not use any media** like it was before.

=== Send from ftp/sftp ===

This installation is applicable while we are remotely connected **from then internet**

  - If the installation file is for example on our personal **home PC**, or even our **cellphone**, we can send it [[en:software:lserver-admin:files:ftp_sftp|through FTP or SFTP]], with an FTP client software like [[https://filezilla-project.org/|filezilla]] or even from our cellphone with a mobile application like **Cx File Explorer** on android.
  - Then we [[en:software:lserver-admin:quickstart:connect2windowsvm|connect to Windows VM]] as an administratir with our account. 
  - We copy setup files on **C:/temp** and proceed with installation.
