A fascinating detail: The zip file is exactly 936 MB (982,401,024 bytes). However, upon extraction, the total folder size is 1.93 GB. The compression ratio (approx. 51%) is unusually low for a ZIP file, indicating that much of the data is already compressed or encrypted. Users have noted that if your downloaded copy varies even by 1 MB (e.g., 935 MB or 937 MB), the setup will fail with a CRC mismatch. This suggests a deliberate checksum trap—potentially anti-tampering or a sign of corrupted mirrors.
Before asking if it works, you must ask if it is safe. Here is how to verify the file before running it: Size: 936 MB is critical
