Really fond of Google chrome…
Is it blocked at your office? but still you want use 
here r the steps … just now explored 
Step 1 : go to C:\Documents and Settings\xxxUserNameXXXX\Local Settings\Application Data\Google\Chrome\Application
(replace xxxUserNameXXXX with ur user name)
Step 2 : copy google chrome and paste, now u will get “Copy of chrome”
Step 3 : rename it to any name of ur convenience eg. i have named as “gchrome”
now open gchrome, your google chrome will be working…
Logic here is they have only blocked “chrome.exe”
