Error/problem in visual studio 2012 css editor

Hello ,

I hope this is the place for this Q.

 I using  vs 2012 pro

1. When I try to build style in the first time after opening  vs

I’m getting this window alart  “Richedit Assert –the specified model could not be found (msptls.dll)”

Clicking ok ,does open the Modify style box.

2. instead for getting css color picker I’m getting a list of color name

Can anyone instruct me how to fix this annoying issues ?

(using  Vs 2012 pro win8 8 pro 64bit)

Thanks
