Cannot get Bitcoin-QT to run in testnet mode I downloaded Bitcoin-QT for Windows 7 into:  

MYUSERNAME/Downloads/bitcoin-0.8.6-win32/bitcoin-0.8.6-win32


I want to run Bitcoin in testnet mode, so I created bitcoin.conf with only the following content:

testnet=1


I put copies of bitcoin.conf into the following folders:

MYUSERNAME/Downloads/bitcoin-0.8.6-win32/bitcoin-0.8.6-win32
User/MYUSERNAME/AppData/Roaming/Bitcoin


When I double clicked on the Bitcoin-QT icon to execute the following, Bitcoin-QT starts up but it does not appear to be in testnet mode.

MYUSERNAME/Downloads/bitcoin-0.8.6-win32/bitcoin-0.8.6-win32/bitcoin-qt.exe


Can anyone tell me why it does not seem to go into testnet mode?

I went to Start > cmd to get the DOS prompt.  I entered the following and it worked:

C:\User\MYUSERNAME\Downloads\bitcoin-0.8.-win32\bitcoin-0.8.6-win32&gt;bitcoin-qt.exe -testnet


But going into DOS prompt to start up bitcoin-qt is a hassle.  It would be easier if I can just double click on the Bitcoin-QT icon.
Create a shortcut on your desktop (or somewhere) to:
"C:\User\MYUSERNAME\Downloads\bitcoin-0.8.-win32\bitcoin-0.8.6-win32\bitcoin-qt.exe" -testnet
and name it "Bitcoin-QT testnet"
