The documentation at:
Refers to a sample response file used for installing the .NET agent in silent mode. The file, SampleResponseFile_DotnetAgent<bitmode>.iss (where bitmode would be 32 or 64) is not in the zip file downloaded from APM Team Center or ACC. Also downloaded the APM 10.7.SP3 and 10.7.0 versions of the .NET agent and they also do not include the sample response file.
Release : 20.2
Component : APM Agents
Per Engineering, the.NET Agent silent installation on Windows system with the .msi installer is still working ok. We just need to clarify the discrepancy between the current DX SaaS docs and the actual silent installation instructions for the newer .NET Agent versions.
