SketchUp has a digital signature imprint from Verisign, so if you receive a message that there is an invalid digital signature or no digital signature, the likely cause is that installation file was corrupted during download.

In that case, clear your browser's cache, and then try the download again. Note: It can take up to 30 minutes to clear the cache.
