I left lots of messages on their boards and personally emailed some of their people but no solution. I sent screen shots, error messages, their own error logs when they told me to all no avail. It has something to do with a certain type of router or something my company used which of course I can't take down. I wasn't the only one that had this problem. I saw 3 or 4 others that complained on their message board. They still haven't figured it out it seems. I gave up.
While there have been a few users who had difficulty getting logged in to install the software, it's a small number. For the registration process to work, you must register with a real and legitimate email address, so make sure you follow the steps properly.
It is entirely possible that you have a firewall blocking the download. If you wanted to use CircuitMaker in a school lab or corporate office you will need to make sure that you have the necessary privileges to install and download software.
There have occaisionally been anti-virus false positives triggered by virus scanners which have out of date databases, or firewalls which block distribution traffic from Amazon S3 or CloudFront services, which we use for software installation and distribution (not only for CircuitMaker but also all other Altium software products). It is most likely you would have the same issues with any Altium software if it's a firewall or permissions issue.
Check that your CircuitMaker registration was completed successfully by logging into the CircuitMaker workspace - workspace.circuitmaker.com and then I suggest getting on the forum and start or join a thread discussing any problems you may be having there - you should find the community lively and also the CM development team are very engaging as well - we all want this software to be everybody's favorite for open source design projects.
That seems obvious - they are mine if I conceive of them. Perhaps you meant what makes them protected, in which case it is the US laws which govern intellectual property (patents, trademarks, copyrights).
I tried it when it first came out and had lots of problems downloading it to get it installed. To their credit, the guys were quite responsive and resolved the issue. BUT it had me do a lot of monkeying around (and I'm working from memory now) by generating or copying some browser security certificates from one browser into another and stuff like that....
In actual operation, it is sluggish, not fun to use at all.
Add to that you kind of need a network connection to run (sure, call me a luddite, but sometimes I run unconnected when doing my designs ... like maybe I'm trying to save a bit of battery power on my laptop or whatever).
I'm not fond of the "open sourcing" my design requirement, but it does have facilities where I think you can "close" up to 3 of your designs until it's ready or something like that. There are plenty of reasons why you might want to keep your design closed ... for example it's a work in progress and there are potential safety issues with the unfinished circuit. Having someone take the unsafe design and use it would be a BAD thing.
However, WAY too many limitations given that there are alternatives.
PCBWeb from DigiKey
DesignSpark from Allied/RS
None of these have restrictive licensing issues or need for Internet.
To use an analogy ... suppose I use free-to-use Eclipse+gcc to build my application but the trade off is any program I generate must be open sourced and freely available to anyone. That probably wouldn't prove too popular.
"This stipulation is analogous to using a software tool to document a musical composition, and agreeing to forgo all rights to the resulting product."
You just share your so called rights ( what exactly makes them yours to begin with? it's just an outdated convention established to support creativity) with anyone that might care. Open source doesn't mean that others get payed and you don't , just that other can get payed too. However you are first to market and you can innovate further before others do.
And the thing about ideas is that they are not like money, you don't run out of ideas if you "spend" them.
"Not sure I share your zeal for surrendering intellectual property rights to my electronic designs."
We use Altium at the day job, but for personal projects I can't justify a license for home use. CircuitMaker is an attractive alternative, but I don't share that zeal, either. And as such that's why I won't get into CM.
And Kicad has been working well for me. Oddly, the open-source tool doesn't require that the things which are the result of using the tool be open source.
"Furthermore, you can use CircuitMaker to create production products, sell millions of units, and become fabulously rich -- the only requirement being that you make such designs open source, which I personally don't regard as being in any way unfair."
Not sure I share your zeal for surrendering intellectual property rights to my electronic designs. This stipulation is analogous to using a software tool to document a musical composition, and agreeing to forgo all rights to the resulting product. How cheap/desperate are we? Google gives us 'free' mail and we surrender all expectations of privacy and ownership. From what i understand, Microsoft is making the same offer with Windows 10 and all user data. Call me a old fuddy duddy (go ahead!), but I think I'll pass.
Are you prepared to do this if requested? What defines "sufficient"?
3.7. Compliance Certification. During the term of this Agreement Altium shall have the right to request that You provide within thirty (30) days of receipt of Altium's written request sufficient documentation to support, and certification of, use of the Licensed Materials in compliance with this EULA's terms and conditions.
Same problem with me, I emailed and complained for 2 or 3 weeks without satisfaction. I left lots of messages on their boards and personally emailed some of their people but no solution. I sent screen shots, error messages, their own error logs when they told me to all no avail. It has something to do with a certain type of router or something my company used which of course I can't take down. I wasn't the only one that had this problem. I saw 3 or 4 others that complained on their message board. They still haven't figured it out it seems. I gave up. I've never had any problem at work downloading or installing any software package until this one. They are doing something unconventional with their loader/installer
You won't have any luck unless you use it from home or something.
