when i start luncher, 'assert: pointer is null' occur and luncher doesn't show up. reinstalling and redownloading doesn't work, turning off firewall is too. i can only start luncher once when install is just completed.

i'm using window7 profe 32bits, and this error didn't occur when i use window7 starter 32bits, and xp.

plz solve this problem.
thx.

nvm
when is start with administrator's authority, this is working.
my reinstalling and redownloading is really in vain by just one merely easy mistake
