Symptoms
After installing or upgrading to the Citrix Online Plugin version 12.0.3, you receive the following message when launching an ICA session hosted on a XenApp server:
“.NET 2.0 or later is not installed, but is required for all the features of Citrix Desktop Viewer to be available. Do you want to be prompted with this message in the future?”
Background
The client machine does not have Microsoft .NET v2.0 installed.
This component is required for the Citrix Desktop Viewer.
The Citrix Online Plug-in was deployed using the default installation options.
Resolution
- If Citrix Desktop Viewer is required in your environment or if .NET v2.0 can be installed on the end point machine [example: sufficient disk space, appropriate permissions ...], then install the missing .NET component.
- If Citrix Desktop Viewer is not required or if .NET v2.0 cannot be installed, you might want to consider deploying the Citrix Online Plug-in without the Citrix Desktop Viewer component.
Refer to Citrix eDocs for the Citrix Online Plugin installation command line options:
