Hi
You will also need to install the files that are necessary for the designer as well.
In the zip file(s) that Reema has directed you to you will find a directory called 'Bin’ whose files you should install as directed by Reema in her post. You will also find two further directories C! Themes Designer and c1 Themes.
C1 Themes designer need to end up as a sub directory of C:/Program Files(x86)/Componentone/Studio for winforms and C1 themes needs to be a sub directory of c1 themes designer.
I can’t see any self extracting utility to do that for you in the zip file so you need to do so yourself.
