I am facing problem in installing APROL R4.2-07 (SLES 12 SP3) in 13th Gen Intel Core i5-13600 DEL CPU. While installing AutoYast I am getting stucked at “Loading Ram Disk” I have uploaded refence image in attachment. I have to install R4.2 in this CPU. So how can i proceed with this. ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/0/0ba00bc34ab56c3483bc8801f88500fabec474e0.png) CPU Detail: OptiPlex Tower 7010 13th Gen Intel Core i5-13600 ( 14 Cores/24MB/20T/2.7GHz to 5.0GHz/65W) - Windows 11 Pro, English - 32GB (2x16GB) DDR4 Non-ECC Memory - NAMD Radeon RX 6300 2GB GDDR6,Full Height,2xDP - M.2 2230 256GB PCIe NVMe Class 35 Solid State Drive - Additional 2.5 inch 1TB 7200rpm Hard Disk Drive - Intel Rapid Storage Technology, OptiPlex Tower Auto Yast Source File used for instalation of AutoYast: [APROL-AutoYaST-DVD-V4.2-070.0.231002-SLE12-SP3](https://www.br-automation.com/en/downloads/software/aprol-process-control/r-42-07/obligatory/aprol-autoyast-dvd-v42-0700231002-sle12-sp3/) ---

I dont have the Answer to your Question, but i can tell you that i had simmilar Problems with R4.2-06. I have tried to Install it on a i5 12th Gen CPU and failed, i did made it thru the Setup process but the OS behaved in strange Ways. I then tried R4.4 an it worked flawless at first Try. Keep in Mind that Aprol R4.2-07 is bases on SLES12 wich was released all the Way back in 2017. I dont think that the Support for Intel Power and Efficiency Cores was implemented at that Time. ---

This was already a topic with you in a Teams channel Here the Statements: 1: from Christian Peham: In my opinion, you will not have success to install the old SLES13 SP3, which is already more than 10 years old on the new hardware. I guess this AutoYast, which you like to use, doesn’t content the device drivers for your new server hardware. I recommend to use a standar B&R APC or certificied hardware from our homepage. [https://www.br-automation.com/en/products/process-control/aprol-hardware/](https://www.br-automation.com/en/products/process-control/aprol-hardware/) Another option, and in my opinion the best, is to install R4.4 with the new OS SLES15 SP4 1. From myself: Who told you that this Hardware will work? This is not tested and evaluated from B&R. See link from Christian. ---

→ possible solutions: 1. APROL R4.4-xx (I recommend the latest one with the latest patch) 2. Virtualisation (e.g: ESXi)
