That trick works best if you reset the clock before it expires. Some software is more sophisticated than others, and once you go past the expiration date, resetting won't help. I've even tried uninstalling and reinstalling, but it leaves something behind that doesn't get uninstalled. Probably something in the registry, if you can find it.

To all who replied - thank you very much. I will download and try the
recommended software.
In the meantime, I tried setting my computer clock back a year, and lo and
behold, DesignWorks Lite came back to life! This technique might also work
for other trial version software that has "expired".

Subject: Re: [TCML] Schematic Capture Software
I had been using the free OrCAD 8.0 Pspice package, and while the schematic
capture may be lacking many things, the ability to simulate circuits was
HUGE!
I just got a Windows 8 PC, and sadly, I don't seem to be able to install
OrCAD. I tried compatibility mode - no dice.
I don't want this to devolve into a Windows 8 bashing thread (no one has the
bandwidth for that), but has anyone installed a free trial version of OrCAD
on W8?
