Calling a function in a standard DLL issue (ARM64)

[sasha]

Hello, thanks for looking at my question.

Our installer has a custom action calling a function in one of our DLLs (when a prior version of the product is installed).
Our product is x64 (mostly).
Now, running the installer on an ARM64 system, the custom action fails with an error that a DLL required could not be run.

Could you, please, explain why that happens? I understand that AI provides a wrapper to call functions in standard DLLs. I also understand that AI is x64-based. So, why does it fail to load our x64 DLL and call a function in it?

Does it rely on some system DLL to make a call and that DLL is, of course, ARM64 and that's why it fails?

Can you suggest a workaround? My current approach is to use PowerShell with crazy method definitions and twists and turns to ensure a proper architecture PowerShell is used.

Thanks!

Hello,

If possible, could you please share with me the following resources:

- a copy of the AIP file

- a download link for the setup

- a download link for the DLL file that is causing these issues

by email at support at advancedinstaller dot com so we can further investigate this?

Best regards,
Catalin

Thanks for the reply.
I would need to obtain a permission to supply the files first.

You are always welcome, Sasha!

And sure thing, there's no rush here - we will be waiting for the resources so we can also run some tests on our end.

Best regards,
Catalin
