[ISS Support Case] "NAD unable to download new application" error
Last updated: September 4th, 2026Description
The customer has provided a new VM for the RDS2 Runtime, and the installation has been completed. The application was initially working fine under the installation admin user. However, when attempting to open the Windows Viewer from other plant HMI user accounts, the error "NAD unable to download new application" error appears. All plant HMI users have been added to the Administrator, aaPowerUsers, and aaIntouchUsers groups, and the server has been restarted, but the issue persists. I also tried redeploying the ViewApp and tested with one of the plant HMI users, which worked temporarily, but only for one user out of ten. The same error has now started occurring for the installation admin user as well. This issue is critical for plant operations, and we would appreciate your urgent support.\
