Hi,

I just installed the latest update v1511.11.0 and when I tried to compile a sketch I got the message: Error compiling core.
I went into Control Panel and Uninstalled the VisualMicro application.  Then tried to reinstall the update, but get the message: This extension is already installed to all applicable products.  Also editor underlines Arduino keywords with red squiggly lines.

Any ideas?

All the previous updates worked fine, and I love the product! 

Thank you!

I'm using Visual Studio 2015 Community Edition and downloaded from your site.  The link on your site takes me to Visual Studio Gallery and I downloaded the latest version for VS2015.

Thanks for your fast reply!

Hi Tim,

I installed the latest version 15.11.12.0.  It installed fine.  I loaded the simple blink sketch and compiled it.  Here is the output of verbose messages.

Thank you!

Hi Tim,

I rebooted the computer and it works now.   
Sorry to cause you grief.
