I did try to run as administrator which didn't have any effect.
However as of now I believe whatever issue I was having has resolved itself. I came into work this morning and launched DraftSight and finally the registration box popped up. Was able to register and everything is working good now. I'm almost thinking that the site that it goes out to give you the registration pop up on the initial run was down, but that doesn't make any sense either only because I was able to install on another PC Saturday and I got the registration pop up. Who knows...
I had this same problem. Installed DraftSight and launched it but it would not open past splash screen. Reinstalled it the next day and got to the registration screen. Must be trying to reach a server that was not available. Working OK now so not a problem.
Thanks Michael, that did it !!!
Specifically, what I did was:
-Found DraftSight.exe in C:\ Program files.... and set "Run as Administrator" in properties as Michael shows above.
-disabled Kasperky antivirus
-set User Account Control to minimum
-double clicked on Draftsight - got the activate screen, and typed in the info (as I had done dozens of times before)
-this time, however, I got an E-mail back, to finish the activation.
I had previously RMB the .exe file and hit "run as administrator", but for whatever reason, it did not work.
