Symptom:
After installing Venafi Encryption Director 6.x, the WebUI client is unable to be displayed. The Windows Administration Console (WinUI) loads fine, but when attempting to access the WebUI, the following error is displayed:
HTTP Error 500.21 - Internal Server Error
Handler "PageHandlerFactory - Integrated" has a bad module "ManagedPipelineHandler" in its module list
Cause:
One known cause for this issue is not having .NET 4.0 installed fully/properly. This is the case if there are no ASP.NET 4.0 entries in the IIS Application pool list.
Resolution:
To Resolve, do not try to manually create the missing entries. Run the following command:
C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i
