SAP and Arm64 version of Windows 11 with Prism emulator (Snapdragon X series)

[Sven]

I'm wondering if anyone has experience with the new Snapdragon X series Windows 11 PCs. My expectation is that all new cloud solutions should work seamlessly through the browser, just like on x64 or x86 systems. However, for other tools such as SAP GUI, Java GUI, ADT (ABAP Development Tools), and even the OpenJDK for Windows on ARM64, the situation may be different. I understand that it's still early days, and some older solutions may never receive full support.

I'm also interested in how well the Prism emulator works for running SAP applications. I’m presuming that even if emulation adds a bit more than 20% processing overhead, it wouldn’t be too significant or even noticeable if everything functions as expected. The challenge is with the drivers and VPNs, which do not work under the Prism emulator.

Despite these concerns, there is already a substantial list of native software for Windows on ARM that’s available today. It will be interesting to see how the ecosystem continues to develop.

[Conclusion] After one week of using Windows 11 ARM-based laptop PC, no issues found. List of installed software as well as the list of x64 processes when everything is running at the same time, is below. I'm thrilled with this outcome.

SAP GUI for Windows 8 Final Release - 64bit, Patch Level: 9 Hotfix: 1
ABAP Development Tools for Eclipse3.44
NW Developer Studio 7.5 SP30
SAP PI Integration Builder tools (swing PI tools ESR and IB) 7.5

In regard to the ABAP Development Tools (ADT): Although a native Eclipse version is available, ADT is not natively supporting Windows on ARM. Using the PRISM translation layer, the x86_64 version of Eclipse incl. ADT should work but as you already mentioned there will be most likely an impact to the performance.

Pls. check [Conclusion] above and the comments below.

 @Sven For ADT: Which version of JRE did you install, x64 or Arm64?

I tried JRE & Eclipse platform for Arm64 and was fascinated with the performance, however after installing ADT plugin, ADT throws an error.

SAP GUI x64 works fine.

@Stephan ADT is not natively supporting Windows on ARM. I used x64 versions of JRE & Eclipse. By the way, did you use Microsoft JRE on Arm64?

[Stephan_Heinberg]

@Sven ADT work now for me, if I install everthing in x64. For other Java programms like JMeter I use JRE ARM from adoptium: https://adoptium.net/de/temurin/releases/?os=windows&arch=aarch64

Just for your information: The ADT installation guide provides a list with all prerequisites: https://help.sap.com/doc/2e9cf4a457d84c7a81f33d8c3fdd9694/Cloud/en-US/inst_guide_abap_development_to... (see page 23)

@wolfgang_woehrleIt would help, if ADT would support Windows ARM native, similar to Mac Mx. The X64 simulation mode works, but it is slow.

JRE & Eclipse Platform work really fast and native on Windows ARM, start up time is 2 seconds, only ADT throws the following error:

ABAP communication layer is not configured properly. This might be caused by missing Microsoft Visual C++ 2015-2022 (x64) Runtime DLLs. Consult the installation guide or download page for further details on how to install this component.

@Stephan glad to hear it works for you now. Just for information, for Eclipse (without ADT) I use Microsoft's https://learn.microsoft.com/en-us/java/openjdk/download

Hi Sven,

in regards to ABAP development tools for Eclipse: Do you know our ADT installation guide? It is our official document. It contains a section with the requirements.

Does the document helps you?

Kind regards,

Wolfgang

Hi Wolfgang, I was curious about this topic, so I just started today with my third Surface device, which is now running on Windows Arm64. The VPN from the Microsoft Store works fine. I installed the latest 64-bit SAP GUI without any issues and also set up non-native Java with webstart ( javaws.exe, version 8 ) to run the PI/PO Swing tools. I couldn't get native OpenJava to work due to the missing webstart, and OpenWebStart didn't recognize the native one. Next, I'll proceed with ADT. So far, running x64 applications is working well. I can't comment on speed in detail, but everything seems much faster than on my other machines. Thanks for the ADT installation guide! On page 16, under "Microsoft Windows 10TM or higher," it might be helpful to specify x64, given that Arm64 is now in the mix. I'll check soon if the emulation works for the other tools I use daily. Thanks again!

Hi Sven,

great. You can get the latest ADT plug-ins and the latest Eclipse client from here: https://tools.hana.ondemand.com/#abap

OK, good luck.

Please let us know if you have further questions.

Kind regards, Wolfgang
