Cause

This issue occurs due to either one of the following:

• An incorrect untar tool is used hence the checksum fails.
• The MIME types used for the NSX Intelligence files.

Resolution

To resolve this issue:

1. Use the right tool to untar the NSX Intelligence deployment file and verify the checksum of the untarred files prior to progressing with installation.
   
   a. Use 7zip for windows to untar the file to avoid causing issues with the checksum mismatch. 
   b. Regular tar command in linux should work. 
   c. Verify the sha1 checksum for the files are same as mentioned in manifest file.
    
2. Update the web server with the MIME type for the respective file types:
   
   * .ovf > (application/vmware)
   * .vmdk > (application/octet-stream)
   * .mf > (text/cache-manifest)
   * .cert > (application/x-x509-user-cert)

Note: MIME type change is only required manually for IIS.
