Cannot Start Application - Double-clicking ConstructConnect Takeoff Desktop Icon Throws an Error

Last Updated: 2020-02-14 08:56

Affects products installed prior to 8/1/2019.


When you double-click the desktop icon, you receive the error below indicating that Windows "Cannot Start Application". 

Windows Cannot Start Application error message


The August 1 installer/updater for ConstructConnect Takeoff is signed using a new security certificate that does not match the original issuer's. 

Because of this mis-match, when the program tries to reach the server and automatically update to the new version, it is blocked (correctly) by Windows. 

We apologize for this inconvenience, but there is a very simple work-around...


You must download a new installer from ConstructConnect's web site and run it to update to the version (the Aug 1 release). 

Once downloaded, double-click to run the installer. 

You may receive a Windows warning that SmartScreen has prevented an app from starting.

Click "More Info" and then "Run Anyway". 

The installer will remove your previous installation of CC Takeoff and install v. 

Going forward, when you double-click the desktop icon, if there is an update available, it will be installed automatically.
