Thanks! I sorted it in the end. Our EDR solution (SentinelOne) was the problem. I disabled it and ran the registration successfully, and enabled it again. It appears the bulk reg key load was flagged as suspect.

While installing the ASR Unified Setup on Configuration Server, the installation is failing at the "registering with Site recovery" step. Please refer to the attached screenshots.
Exact error message:
Process error: MTRegistration:: registerMT encountered exception [at i:\src\release\inmage-azure-siterecovery\host\cdplibs\win\registermtmajor.cpp:MTRegistration::importMTRegistryHive:204] registry import failed with error: access is denied.
