Unable to install Firefox on windows


I previously downloaded firefox but uninstalled it due to malware problem. After fixing the malware problem with Malwarebytes, I re-downloaded the Firefox 18 setup file. When I click on it, it starts extracting and then a pop up window appears asking whether to install as administrator or as current user. When I say as current user nothing will happen. When i selected administrator, they prompted me for a password but I did not set any password for the administrator account in the first place.

Additional System Details


  • User Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.0; Trident/5.0; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.5.21022; .NET CLR 3.5.30729; .NET4.0C; .NET CLR 3.0.30729; InfoPath.2)

If your local user then, your not able to install Firefox.

Instead of Administrator account, if you the account with administrator rights, make use of that account.
