Pull Request Overview

This PR fixes the 64-bit uninstaller for NVDA by ensuring the installer reads from the correct registry view. The issue was that the uninstaller couldn't locate the installation directory because it was reading from the 32-bit registry view instead of the 64-bit view where the installation path is stored.

Key changes:

  • Added SetRegView 64 instruction to force reading from 64-bit registry view before retrieving installation directory
