After installing your KIS 2011 chinese version lets see how to convert it to english version but let me inform you that I have installed chinese installer in around 9 to 10 computers (my friends & relatives pc) and converted it to english but it worked successfully only in 2 PC rest it gave the license error after restart(so again i had to reinstall the application in chinese version only ) so incase you are fine using the chinese version dont use this trick as its mostly giving error after restart
Now restart your computer and keep tapping F8 function key on top of the keyboard till you see the screen as shown below because we need to restart the computer in safe mode
Highlight safe mode and press enter
Select the operating system where you have installed KIS & you need to login using the account having admin rights
You will see a warning message click on yes as we need to work in safe mode
Now XP users click on start & run,Vista & Windows 7 users press Windows Key + R to open the Run command window.
In the run window here type regedit and click on ok
On the left hand side navigate to the following location
HKEY_LOCAL_MACHINE \ SOFTWARE \ KasperskyLab \ protected \ AVP11 \ environment 
Once you click on environment,on the right hand side look for SkinSwitchDisabled, double click it and change its value data from 1 to 0
Now look for localization, double click it and change its value to en and restart your pc
Now if you are lucky enough you will see your kaspersky product in english this time with 365 days license validity(which i got only 2 times out of 10) else you will see the error like above
You must be thinking that if this trick is not working why I shared with all,well this trick was working with older chinese versions but with this new installer its not still i shared if any member would like to try his luck as I am still playing with the registry to make this trick work if anyhow I find a solution that would be 100% working will share with all
