==========================================
I'll assume you have Winzip. If you don't go to
www.google.com, do a search for WinZip and download it.
1. Download the HTS zip file and unzip it using full path names. You do this when you doubleclick the zip file and get a file save dialog. You will see a check box on the bottom left of the dialog that says "Use Folder Names". Make sure it is checked.
2. Go to
http://java.sun.com/j2se/1.4.1/download.html and click the "Windows (U.S. English only)" row and the "JRE" column that says "download". Scroll to the bottom of the page that comes up and hit the "Accept" button. Click "Download j2re-1_4_1_01-windows-i586.exe ." on the new page that comes up. Save it to disc or open it right there, you will then get a series of instructions on how to download it. It is pretty simple.
3. The JRE is a Java Runtime Environment. HTS is written in Java and the JRE is what runs the program, that is why you need it. Once you have downloaded and installed it, double-click hts.bat to run the program.
4. Normally, you would then create a tech group for the files that you want to run. I'll do that for you and show you what you need.
5. Click your Windows Start | Run... menu item at the lower left of your screen. Type in "notepad.exe" without the quotes. Copy and paste the stuff below into the file that opens with notepad (I'm assuming you are running 1.03, if not, change the techgroup.name=1.03 to something else):
#=================== COPY STUFF BELOW ===================
techgroup.name=1.03
techgroup.descfile=C:\\Program Files\\Strategy first\\Hearts of Iron\\config\\text.csv
techgroup.file.1=C:\\Program Files\\Strategy first\\Hearts of Iron\\db\\tech\\submarine_tech.txt
techgroup.file.2=C:\\Program Files\\Strategy first\\Hearts of Iron\\db\\tech\\air_doctrine_tech.txt
techgroup.file.3=C:\\Program Files\\Strategy first\\Hearts of Iron\\db\\tech\\armor_tech.txt
techgroup.file.4=C:\\Program Files\\Strategy first\\Hearts of Iron\\db\\tech\\artillery_tech.txt
techgroup.file.5=C:\\Program Files\\Strategy first\\Hearts of Iron\\db\\tech\\electronics_tech.txt
techgroup.file.6=C:\\Program Files\\Strategy first\\Hearts of Iron\\db\\tech\\heavy_aircraft_tech.txt
techgroup.file.7=C:\\Program Files\\Strategy first\\Hearts of Iron\\db\\tech\\industry_tech.txt
techgroup.file.8=C:\\Program Files\\Strategy first\\Hearts of Iron\\db\\tech\\infantry_tech.txt
techgroup.file.9=C:\\Program Files\\Strategy first\\Hearts of Iron\\db\\tech\\land_doctrine_tech.txt
techgroup.file.10=C:\\Program Files\\Strategy first\\Hearts of Iron\\db\\tech\\light_aircraft_tech.txt
techgroup.file.11=C:\\Program Files\\Strategy first\\Hearts of Iron\\db\\tech\\naval_doctrine_tech.txt
techgroup.file.12=C:\\Program Files\\Strategy first\\Hearts of Iron\\db\\tech\\naval_tech.txt
techgroup.file.13=C:\\Program Files\\Strategy first\\Hearts of Iron\\db\\tech\\nuclear_tech.txt
techgroup.file.14=C:\\Program Files\\Strategy first\\Hearts of Iron\\db\\tech\\rocketry_tech.txt
#=================== DON'T COPY THIS ===================
6. Save the file into your HTS folder. Call it whatever you want to call it. While running HTS, Select File | Open from the HTS menu. Open the file you just saved in notepad with the stuff above.
7. Now you should see the tech tree. You can drill down till you get to tech applications and tech levels, just like in the game. Select a node by left clicking your mouse button on it. You will see descriptive text in the top left describing that tech. If you then right click on that node, you will see a bunch of menu choices. Ignore them all except the 3 at the bottom (Research, Schedule, Lock). If you Research a node, it makes it such that the scheduler things it has already been researched and will ignore it when scheduling. If you Lock a node, that means the program will never change the state of the node from researched to unresearched or vice versa. You generally don't need to do that. If you Schedule a node, it will display a bunch of stuff in the bottom right that shows the scheduling.
8. You can select more than one tech level or application by holding down the shift or control keys while left clicking. Shift will select ALL nodes between any two clicks. Control will select ONLY the nodes you click. You can then schedule multiple techs that way.
9. If you want to do research for a specific country in a specific scenario (like USA in 1936) go to the top level node of the tree and right click. Select "Open Starting Techs File..." from the menu that pops up. Navigate to the HOI scenarios folder. Click on one of the folders you find there like 1936. You should then see a bunch of *.inc files. Find the country you want and double click it.
10 Once you have done that, a bunch of techs will now be researched and locked for you automatically. You can then start scheduling just like you were playing that country in that scenario.
11. If you want to save what you have scheduled, you can copy and paste anything from the info window or schedule window. Just left click in the screen, hold down the mouse button and drag to the bottom. Once you have selected what you want to save, hit Control + C and then open up Word or notepad or something and click Control + V. The editing commands are pretty much just like you would find in Word.
