Users should always verify the integrity of the installation media before installing a VMware product.
Always verify the SHA1 hash after you download an ISO, offline bundle, or patch to ensure integrity and authenticity of the downloaded files. If you obtain physical media from VMware and the security seal is broken, return the software to VMware for a replacement.
After you download the media, use the MD5/SHA1 sum value to verify the integrity of the download. Compare the MD5/SHA1 hash output with the value posted on the VMware Web site. SHA1 or MD5 hash should match.
