We noticed that Dynatrace APM is affecting the IFS EE client download.
Reason behind this is due to feature called RUM (Real Time Monitoring) in Dynatrace and it automatically injects a javascript tag to each html file in the application it monitors.
IFS client runtime contains a html file named employeedata.htm and it’s included in the manifest in group Ifs.Application.Person. With RUM enabled, file content is modified dynamically so clickonce reject downloading the person.dll meaning IFS forms depending on person.dll will not work.
As a solution, a custom rule can add in Dynatrace settings to avoid injecting Javascript to this particular file.
Cheers!
