Our application uses Add-in Express to add a form to the Outlook Explorer, docked right. When running on Arm64 devices using 64-bit Outlook this causes Outlook to crash on startup.
I have reproduced this issue in a simple test project available here:
https://macroview365-my.sharepoint.com/:u:/g/personal/josh_macroview_com_au/Ec4y2kV_X95DlxCT_RLQkkwBA2qts1YVnhDmmFvWD1ahig?e=yaWNld
This test add-in loads fine on x86 architectures and displays an empty task pane as expected. Loading it on Arm64 using 64-bit Outlook results in Outlook crashing.
Crash dump analysis indicates this is caused by an access violation in USER32.dll, originating from IntResource64.dll.

Hello Josh,
We suppose an antivirus is blocking IntResource6 which is normally unpacked to the Temp folder and then loaded from there.
Copy IntResource.dll and IntResource64.dll from {Add-in Express installation folder}\Redistributables to the folder where your add-in is registered. On the development machine that would be the output folder of your add-in project; on the target PC that would be the installation folder of your add-in.
Does the issue persist?

Hi Andrei
Yes we have already copied both IntResource and IntResource64 to the add-in directory. We’ve also confirmed there is no antivirus software running. We have multiple customers reporting this issue.
Are you able to reproduce the crash using the attached repro project on one of your ARM devices?
Thanks |

Hello Josh,
We don't have an ARM64 device at hand. I will be able to check whether we have such a device at all not earlier than in two weeks.
The call stack above mentions IntResource64!AdvancedCommand quite a lot of times. Although we do have such an entry point, and although it does have some implementation, this entry point isn't used in our code: no calls to this method exist.
Do you get that stack trace with your simple test add-in project?

Hi Andrei
Yes, that stack trace was taken from the simple test add-in project when it crashed Outlook.
Our advice to customers when this was previously reported was to use 32-bit Office on Arm64 because 32-bit Outlook on Arm64 does not crash using the same code.
Unfortunately it does not appear to be possible to install 32-bit Office on Arm64 devices anymore, so this workaround is no longer possible.
If you don't have access to an Arm64 device you can instead create a Windows 11 Arm64 virtual machine in Microsoft Azure: https://learn.microsoft.com/en-us/windows/arm/create-arm-vm
Perhaps this is the better option for you?
Thanks
Josh |

Hello Josh,
Thank you.
Solving organizational issues. We seem to have found an ARM device. There's a suspicion though, this isn't an ARM64 device, though. I hope that we'll run your test add-in on that device tomorrow.

Hello Josh,
Yes, we were able to test it to reproduce the crash. Now we prepare to debug the issue. That may take some time.

Hello Josh,
We don't have any news so far, sorry. Hopefully, things will become clearer later this week. |
