Before attempting an installation, ensure your system meets the following:
| Component | Requirement | |-----------|-------------| | OS | Windows 7 x64, 8/8.1 x64, 10 x64 (20H2 or earlier recommended), 11 x64 (with testsigning enabled) | | Processor | Any x64 CPU with VT-x/AMD-V (for driver signing workarounds) | | RAM | 2 GB minimum | | Disk Space | 50 MB for drivers + additional space for emulated dumps | | Permissions | Local Administrator account | | Secure Boot | Must be disabled (for unsigned driver installation) | Compatible OS: Windows 10/11 x64 (ensure latest updates)
