Check for existing installed software

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 }}”

Probably check: https://docs.ansible.com/ansible/latest/user_guide/playbooks_conditionals.html

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