Unable to start botchief.;

I have bought Dev license and I am not able start BotChief.

I am running on bot chief on windows xp. When I started, it had an update and after updating to the latest Ver 1.4.3 I got a Unhandled Exception - Microsoft .Net framework pop-up error. The error says

"Could not load file or assembly 'whitehatboxpack version =1.0.0.0 culture=neutral, publickeytoekn=null or one of its dependencies. The system cannot find the file specified.

Can you pls check?

I am getting the same error when i try in windows 8 OS.

Hello, please add our Skype account: whitehatbox we will check it for you via remote control.
Also please make sure you have installed .net 3.5 thanks.

Hi,

Based on our skype discussion, I installed the .net 3.5 using 'Turn Windows features on or off' on windows 7 and installed the .net 3.5.1 (I cannot install .net 3.5 version - this version gets updated to 3.5.1 automatically.)

I still continue to get the same error.
