Introduction

We recently had an issue where a customer phoned in with a problem. The problem was that Revit did not start up. It returning an Autodesk Licensing System Error 1 as shown below.

Process

Upon searching for the solution on the internet I found the following site on the Troubleshooting Page on the Autodesk Knowledge Network.

https://knowledge.autodesk.com/support/revit-products/troubleshooting/caas/sfdcarticles/sfdcarticles/Licensing-System-Error-1-when-launching-Revit-2017.html

On this site there were five possible solution. I went through the first four solutions without any success on solving the problem.

Solution number five was to reinstall the Microsoft Visual C++ Runtime programs on the PC. I  followed the link and then another getting to the following page:

https://knowledge.autodesk.com/search-result/caas/sfdcarticles/sfdcarticles/How-to-remove-and-reinstall-Microsoft-Visual-C-Runtime-Libraries.html

On this page, the process of uninstalling and reinstalling each of the different C++ versions could take a long time to do. The alternative was to use an alternative process to auto re-install all these C++ programs using an all-in-one installer. I downloaded this installer from  the following page: https://www.majorgeeks.com/files/details/visual_c_runtime_installer.html

I then ran the app. The app wanted me to reboot as it want to run on a freshly rebooted system. So I had to do a reboot first.

Starting the app it wanted the user to confirm by entering ‘y’ for yes. After the app went had gone through the process of reinstalling all the MS C++ programs it asked the user to press a button to finish.

lic error1 - 2

I closed the app and hereafter Revit starter successfully.

Conclusion

I have come across this MS C++ all-in-one reinstall tool before but this time it solved the problem. I hope this information will assist you in solving Autodesk Licensing System Error 1 problems in the future.
