does not work . error: unable to find project or library

Hi,

The trouble is, is that the toolbar has become disconnected from the VB Addin. I suspect you've managed to delete the Addin, so all you now need to do is remove the Toolbar. To do this:

• Right click on any toolbar, perhaps even in the space between buttons
• Select Customise toolbar,
• Search for 'CodeCogs', often at the bottom of the list, selected this and then click delete

Hopefully your toolbar will be removed. Now install the equation renderer again from scratch.

Hope this works for you; let me know if you still have problems. I aiming to release a new addin within the next few weeks, which will automatically solve all of these problems.

Best wishes, Will
