I used multisim 9 evaluation an the period expired. I then downloaded multisim ver 10 and installed it. When I try to run the software it says the evaluation period is over. I guess it wants an activation code, how can I get one to try this software?
If the evaluation license timed-out there is nothing that can be done to revert it, other than to install the software in another computer. You could also contact the Sales department, 1.800.263.5552, and ask to speak to the account manager for your region, talk to them about your need to evaluate the product and that your evaluation timed-out.
