Installation error with failure messages on dlls from ERDAS IMAGINE 2016.
Cloud based virus scanners (such as Panda Virus scanner) use a cloud database to check files and this process may be slowed down when there is a network congestion. The slowdown prevents files from being available for the installer when needed and may result in installation failure.
Perform the install process when Network traffic is not congested.
Copy the installers to a local drive and install from the local drive.
