OK, I have taken this from the Downoad page. Just follow the instructions:
TO CREATE SHORTCUT TO DESKTOP MANUALLY
NOTE:
This is for people who may be experiencing problems with IJ loading or not loading the IJ shortcut.
1. If the shortcut fails to materialise on your desktop or the path is incorrect in the "target" window, please try reloading the game first.
2. If this fails to solve the problem please follow the following instructions.
For those who have the IJ Icon on their desktop:
Right click on the IJ Icon
Select Properties
In the target box, copy and paste the following:
-mod:IJ -show_err after RomeTW-BI.exe. Make sure you leave a space between .exe and -mod:IJ -show_err.
2. If there is no Icon on your desktop then please follow these intructions:
Go the folder where II has been installed
Right click on the BI.exe icon
Select "Send to Desktop"
The BI.exe Icon should now be on your desktop.
Right click on the Icon
Select Properties
In the target box, copy and paste the following:
-mod:IJ -show_err after RomeTW-BI.exe. Make sure you leave a space between .exe and -mod:IJ -show_err.
