I have an older X20CP0291 and just installed latest Automation Studio (4.12). After upgrading with AS4\_HW\_X20CP0291 I created a new project and detected the hardware correctly over the network but… Automation Runtime is missing and I can’t seem to find it anywhere and since I only have a trial license for AS I can not use the automatic download. So my question(s) are as follows, is it at all possible to use this old CP with a downloadable version of AS, and where do I find the necessary files for HW and AR? Thanks in advance. ---

Should still work, but you have to use ‘Show Also Legacy Elements’ on the hardware related dialogs: ![image](https://europe1.discourse-cdn.com/brcommunity/original/1X/a19bbd71aca4934066d7a87ad182b631ce190f0f.png) ---

So far everything is OK but I get “Selected CPU cannot be used because there is no valid Automation Runtime Version installed” ![bild](https://europe1.discourse-cdn.com/brcommunity/original/1X/3b6a1ffa1b227a727f04ae7f969017c4e4628cf6.png) And I haven’t figured out where to get a AR to download. Search the download page at B&R without any luck, but that could be me 😉 ---

If I create a new project and detect the hardware (which is correctly detected) I get a “Version Mismatch” dialog which complains about AR: X20PC0291. The the only viable option to continue with a trial license is to “Ignore Mismatch(es)” but that doesn’t really help. I have installed AS4\_HW\_X20CP0291 as a local upgrade but from there I am lost and still no AR available. ---

Yep, looks this CPU is historic now ☹ Just move to AS 4.1.17 which can be used without a license. There is an AR F2.33 integrated. If you plan to use a B&R control professionally you should consider using a newer control. ---

Thanks, I will try your suggestion. Do you have an idea what a modern replacement of X20CP0291 would be? ---

the appropriate successors are the ‘Compact-S’ CPUs, e.g. X20CP041x [https://help.br-automation.com/#/en/4/hardware%2Fx20cp04xx\_allgemeines%2Fx20cp04xx\_allgemeines.html](https://help.br-automation.com/#/en/4/hardware%2Fx20cp04xx_allgemeines%2Fx20cp04xx_allgemeines.html) ---

> [@kmpm](#): > > I have installed AS4\_HW\_X20CP0291 as a local upgrade but from there I am lost and still no AR available. Th AR (Automation Runtime) is the operating system and must be installed separately from the specific HW module. AS V4.12 still supports this very old HW and AR, but it is not installed by default. You can install the AR version F2.33 for SGC (System Generation Compact), which is an AR which supports the X20CP0291. As you have the trial license, you need to download the exe from the website and install it in the ‘Local’ tab of the Tools / Upgrades dialog. ![image](https://europe1.discourse-cdn.com/brcommunity/original/1X/2251f72cf3ecdcdc148000c1151f96c370b46ea8.png) Here’s the link to the download: [V4.0 AR Upgrade (F0233\_X20SGC) | B&R Industrial Automation (br-automation.com)](https://www.br-automation.com/de-ch/downloads/software/automation-studio/ar-upgrades/v40-ar-upgrade-f0233-x20sgc/) ---

For the X20CP0291 you still get a runtime version in your new AS4.12 in my opinion Please open “Tools → Upgrades” Then switch to “Automation Runtime” and filter for “F2.33” ![image](https://europe1.discourse-cdn.com/brcommunity/original/1X/ff2bb967b58cb1fd5555455a154a8dacd620a65a.png) The so called “SGC” is your X20CP0291 ---

Hi Christoph, I found your answer very helpful to me since I’m struggling to get my X20CP0291 up and running. I installed AS 6 which I suppose is too new to the CPU. However, I’m struggling to find a download from B&R website that allows me to download the AS 4.1.17 that you mentioned. Also, to run AS 4.1.17, do I need an old Windows? Thank you for your help 👍 ---

Hi @Weiming_Zhao , I see that AS 4.1 available on our downloads page: ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/5/53ccb7d9790c0dfab7a18cc4e538522a24fdca96.png) Regarding the OS: ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/6/69b444d99fce67216d5226e58bd85a9537a7871d.png) AS 4.1 is not supported on Windows 11, not necessary means that doesn’t work on Windows 11 but just not supported. Normally in this case we install Automation Studio on a virtual machine, with the operating system supported. ---

Hi Valerio, Amazing, i believe I can take it from here 👍 Thank you for your help
