It might be better to send your request to ZMT via email. Could you please send an email to "s4l-support@zmt.swiss" address? Thanks

Dear all, Thank you for your responses. The trick was in not "just" to disable the antivirus, but to completely uninstall it. Then the activation worked. Regards, Spuky

as far as I know you can download it the software itself on all your machines, only when using it does it occupy your license, so you can only run one instance on one machine.

Okay, a short update on this issue: I did absolutely nothing and it is fixed for me some how... There might have been a windows update that fixed the problem, not sure about that though. Curious if others have seen similar result.

Downloaded V5.0 Lighty and the tutorials work - thank you!

Problem solved, my Antivirus was not letting Ares through.

my problem was solved. Thank you.

Were you connected to the internet during the activation process? Could you please specify what windows version you are using?

Yes, that is correct.

@habib Thanks a lot...I solved the problem already !

Sim4Life's installer automatically copies required dll files. The files are official Microsoft libraries that Sim4Life redistributes. On some platforms, the files fail to copy and this causes the error message to appear. The solution is to use the official installer for Microsoft Visual C++ 2010 Service Pack 1 . https://www.microsoft.com/en-us/download/details.aspx?id=26999
