Check for existing installed software

[Nitrous]

How can I incorporate this registry check before my playbook runs to install .net 4.8:

(Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full").version -lt 4.8

The above should only run my playbook, if 4.8 isnt installed. If version is less than 4.8 run the below playbook, else skip

My playbook to install .net 4.8:

- name: Copy .net 4.8 Files

  ansible.windows.win_copy:

    src: /etc/ansible/roles/net481/files/ndp48-x86-x64-allos-enu.exe

    dest: C:\Scripts\

    state: present

- name: Install .net 4.8

  ansible.builtin.script: /etc/ansible/roles/onprembaseline/files/net48.ps1

  register: script_run

- name: Reboot after .NET 4.8 Install

  ansible.windows.win_reboot:

Thanks.

Not a ansible hero here, but i think you can do something with the when: command in your playbook. 

So somewhere in de the task where you check the version you will do a

register: dotnet_version

And in the taks where you execute it: 

when: "'4.8' in {{ dotnet_version }}"

This is what I get:

TASK [net481 : Check if .net 4.8 is installed] **************************************************************************************************************************************************************************
task path: /etc/ansible/roles/net481/tasks/main.yml:1
[WARNING]: conditional statements should not include jinja2 templating delimiters such as {{ }} or {% %}. Found: '4.8' in {{ script_run }}
fatal: [xxxxx]: FAILED! => {
    "msg": "The conditional check ''4.8' in {{ script_run }}' failed. The error was: error while evaluating conditional ('4.8' in {{ script_run }}): 'script_run' is undefined\n\nThe error appears to be in '/etc/ansible/roles/net481/tasks/main.yml': line 1, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: Check if .net 4.8 is installed\n  ^ here\n"
}

Role is this:

- import_role:

      name: net481

    when: "'4.8' in {{ script_run }}"

Task Ran:

- name: Check if .net 4.8 is installed

  ansible.windows.win_shell:

  register: script_run  - name: Install .net 4.8, if not installed

  ansible.builtin.script: /etc/ansible/roles/onprembaseline/files/net48.ps1

  register: script_run

Use idempotent way. It will be installed if it has not already been installed

        -   ansible.windows.win_package:

            path: 'c:\path\to\ndp48-x86-x64-allos-enu.exe'

            product_id: "{BAAF5851-0759-422D-A1E9-90061B597188}"

            arguments: "/q /norestart"

Thanks.

I have a pretask before installing, where it copies files to the target server, and then run your idempotent way.

How can I do a check, before copying the .net 4.8 exe, if 4.8 exists, and only run the copy/install if .net 4.8 isnt installed/exists.

If it exists, then skip.

Thanks

hm. try to use win_reg_stat with register variable to determine what version your need is installed/not installed https://docs.microsoft.com/en-us/dotnet/framework/migration-guide/how-to-determine-which-versions-are-installed#use-registry-editor

and wrap all other installation tasks with block and when condition

Thanks, mind showing me an example, on how to use the  win_reg_stat with register variable?

Bonjour. je suis nouveau dans l'utilisation de ansible. Besoin d'aide

Comment pointer sur la nouvelle version de ansible puisqu'on me dit que ansible2.7.10 est dépassé.

voici le message d'erreur. Je vous remercie.
