I am very new to using this package and cannot get even one of the provided examples to work due to an error when the synth command is called: "file synthopt.plugin not found". Simple code:

Code:
sysuse synth_smoking, clear
tsset state year
synth cigsale beer(1984(1)1988) lnincome retprice age15to24 cigsale(1988) cigsale(1980) cigsale(1975), trunit(3) trperiod(1989)
I've followed the documentation and the problem seems to be that I am using Windows 10 and the plugin doesn't come with the initial package install. I've found the plugin and can save it to the ado directory, but that doesn't seem to work. There is some note on the author's site mentioning that the plugin needs to be compiled (https://web.stanford.edu/~jhain/fqa.htm), but that is beyond my level of technical knowledge. Can anyone help?

Thanks!
