Installation error 0x80072ee7 - Unspecified Error - airgapped install troubleshooting

Question

Installation error 0x80072ee7 - Unspecified Error 
 Airgapped install - was able to pass the asp.net parts - downloaded 7.0.18 and that part passes in the logs 
 
 Logs look to be missing Solarwinds_Orion_MaintDateCheck (state:absent default:requested) - Where do I get that file to install?

Hi steve4gru , 
 I am not tracking any issue with the installation. I recommend to use latest version 1.2 where we have installer improvements. I believe you use older version based on the older .NET you are mentioning. 
 If you still experience any issue with installation, please reach out to support team. 
 Thank you 
 Martin
