Quick update - I have installed Circuit Studio (CS) using a trial license on my Win7 32-bit desktop and experienced a few minor issues that were resolved with a reboot of the system. I'll document details in the review. I installed CS on my Win7 64-bit laptop using the one year license and had no issues at all. I'm using that while on the road now. I'm using it with and without internet access and capturing the difference in functionality.
I did some work last week to change some Altium Designer SchLib and PcbLib libraries into IntLibs that I read CS required. I was pleasantly surprised that after I installed CS and was greeted with the initial screen, that CS will also use SchLib and PcbLibs, so I will try that out as part of my review.
So far, I'm spending most time finding where things are at in the new user interface - that is not to say it is difficult, just it is different. I can see myself missing this new UI if I ever go back to AD. Some things are easier to find and much clearer.
