When you get to the download requirements page you just click the link of the OS you're running. I'm running it on Win 7. I ran the VMA and CDC on Linux (they’re all coded by Patrick Chevalley).

After clicking the link you'll be redirected to SourceForge. Some browsers (Google Chrome) and adblockers may block the SourceForge page because of the earlier predilection of SF bundling PUP's (Open Candy) with some installers/binaries. They have cleaned their act up in recent months though.



It is wise to give the installer a quick scan with any AV/anti-malware programs before you run it though just as a precaution.

 

OK, good luck. While you're at it ....

Yes, they all link. You can open VPA at Jupiter then open CDC from VPA itself and it will show you Jupiter's position in CDC. At least they're accurate about the GRS position, unlike some other French astronomical software *cough* Stellarium lol. Chevalley's on record as saying his stuff will always be freeware as he'd rather astronomers bought another eyepiece than spend money on software. I like his attitude. I have French relatives and I know that software development is huge in France as the government invests money into it.

 

Is it a software or a hardware problem? I converted my old Belnea laptop to Ubuntu 14.04 Trusty Tahr LTS a couple of years ago after Vista crashed and burned. I got a perpetual BSOD so wiped it and installed Ubuntu from an image burned to a DVD. You can download an image from the Ubuntu site. I have a Lenovo latop preinstalled with Ubuntu now. Who needs an anti virus lol?

You can see the Belnea here running Ubuntu a couple of years ago with a Mac style dock. Stellarium and KStars are on the dock, as well as the Vivaldi, Firefox and Chromium browsers. Stellarium works really well on UNIX, best not to talk about the Windows version lol.
