This issue is caused by network firewall restrictions or internet proxy blocking downloads of our installation files. Please contact your IT support staff or network administrator, they will need to whitelist our domain and In order to download our software some companies have to allow their users to install from websites they trust. Adding our domain to the whitelist will allow users to download the eCompliance AuditTool to perform audits.

Also remember that the eC-AuditTool, installs inside the user profile and doesn't require administrator to install inside the program files. It is less intrusive and is installed per user profile so permissions are isolated inside the permissions of the user profile.
