I'm start in Mars, place nine vaporator in a planet and open graphs->air sample window. And vaporator affect to nothing. No mater how long i wait, water vapor in atmosphere is always zero (air sample window). WTF?

You want to win the Mars scenario? OK. First stick down a few CO2 generators and then hit the planet with a few ice comets. Then, provided the ice caps are not to massive, place down a few biome factories. When there are a few stable biome zones, place down a few information age cities, and max agriculture and drop science to zero. Then just wait for requirements to be passed and you win.

I decided to ditch the batch file which came with the .zip. Apparently mounting in the bat doesnt work, or atleast it causes something to go wrong. Here is what i did to get this to work :

start dosbox
mount a [x:\path here where\your simearth\install files are\located] ex. my line would look like this -> mount a c:\games\old\tmp
a:
install.exe [DONT run the setup.bat]
select drive A: [where you are installing from]
select drive C: [where you are installing to]
after this you can select screen resolutions and sound devices you like the most.
select preferred language
you can check the setup once more before programs copies the files.
press SPACE after copying is done.
once installation is complete, go to your new simearth folder and run simearth.exe.
Enjoy.

I assume reader has allready mounted hes/hers game directory to c: or similiar, so the final path might look somethign like this -> c:\simearth.

edit.
For some reason i didnt realize i replied to a post from page 9. Oh well, if someone still has this problem, this might help them
