Error instaling Cyclone V device support for Quartus Web Edition

--- Quote Start ---

I have downloaded Quartus II web edition, installed it succesfully, but i have encountered an error trying to add Cyclone V support (cyclonev-15.0.0.145.qdz file)

I'm also coming up against this exact problem - even with the Quartus II 15.0.1.150 Update installed as well.

The other odd thing I've noticed is that, despite running Windows 7 Pro (x64), when Quartus starts up and asks me if I want to install device files, and I say 'Yes', it then says 'Quartus II software cannot launch the Device Installer for Windows 8 and newer operating systems'.

'arria10_part1' looks like it could even be a valid name for one of the three Arria 10 device support files (Subscription Edition only), but why would a Cyclone V device support file be referencing that ?

It seems like there might be a bug with the web edition which try to include the Arria 10 devices when you are trying to install the Cyclone V devices. As I understand it, the web edition does not support Arria 10 devices which may explain why the error talks about Arria 10.

I believe you might need file a service request to Altera to report this to see if there is any workaround.

Essentially, it looks like you have to install Quartus II and any device support files at the same time. This worked for me.
