I just downloaded the free trials for Cisco Prime, vNAM, and IP express. Not one of the downloads has a file extension, and adding .exe or .msi does not allow them to install. How exactly do you run an installer for the downloaded files?!
exact file names as downloaded (with extensions visible):
cpipe_win (~80mb)
pcvn_61 (~302mb)
eval_pis_22 (~3gb)
No trial license was referenced, and even if needed, there is no where to put a license since the applications do not appear to be installable
