The reason that the Download option is greyed out is because you have to first configure and enable downloading Standalone Applications in Performance Center. The steps for enabling downloading can be found on page 93 from the installation guide. The link is posted below:
For Reference, this section explains the steps necessary to enable you to download standalone applications from the Download Applications window.
To access: From the Performance Center navigation toolbar, click (the hamburger icon) and select Download Applications (under Applications).
To enable downloading standalone applications:
- Insert the HP ALM Performance Center Additional Components installation files and navigate to the Additional Components directory. This directory contains the applications' execution (.exe) files.
Note: The necessary .exe files for downloading VuGen, Analysis, Snapshot Viewer, Standalone Load Generator, Monitor over Firewall, and MI Listener, are located in the Applications directory, which is contained within the Additional Components directory.
- On the Performance Center server, navigate to the Downloads directory, which is located in [Performance Center Server installation directory]PCWEBDownloads.
- To enable downloading an application, copy the relevant execution file (.exe) from the Additional Components directory on the DVD to the Downloads directory on the Performance Center server.
Note: You may need to refresh the Download Applications window for the changes to take effect. The easiest way is to log out and log back in to My Performance Center.
I hope this helps.
