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.
