Hi Experts,<br />
<br />
I am having problems with installing my program after publishing it with Visual Studio 2008 using the OneClick Publish option. When I try to install the program, I keep getting this error ... Strong name signature not valid for this assembly Extensibility.dll. &nbsp;I am very new to programing and have no clue what to do to get this to work. &nbsp;<br />
&nbsp;I have attached the error log for the installation.<br />
<br />
Thanks, <br />
Stan<br />
