Currently, Adobe Creative Cloud applications, including InDesign, do not have ARM64-compatible builds available for Windows on ARM devices. As of the latest information, Adobe's Creative Cloud desktop apps primarily support Intel and AMD 64-bit processors, and there is no official support for ARM64 versions of these applications. This means that you may encounter issues like the error code 0xc000007b when attempting to install or run these applications on your Surface Laptop 7 with a Snapdragon X Elite processor.
Regarding your specific questions:
- ARM64-compatible builds or test versions of Creative Cloud apps do not exist at this time.
- There is no publicly available official roadmap or estimated date for when Adobe will provide Windows-on-ARM compatibility for Creative Cloud apps.
- An official statement from Adobe confirming the lack of support for Creative Cloud on ARM devices would need to be requested directly from Adobe's support or customer service team.
For now, you may need to consider alternative solutions for your university exams, such as using a different device that supports these applications or exploring other software options that are compatible with ARM devices.
