How Can We Help?

Digital signature is invalid or missing

 NOTICE: In observance of the Memorial Day in the U.S., Trimble employees will be home with friends and family on Monday, May 29th. All emails will experience a delayed response during this time.

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.
