    <description>&lt;P&gt;Hello&amp;nbsp;&lt;a href="https://forums.autodesk.com/t5/user/viewprofilepage/user-id/2500771"&gt;@Daniel_Voinkov&lt;/a&gt;,&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Try this link instead and conduct the same steps. &lt;A title="The latest supported Visual C++ downloads" href="https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads" target="_self"&gt;The latest supported Visual C++ downloads&lt;/A&gt;. If this does not resolve it try the following steps:&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;OL&gt;
&lt;LI&gt;Make sure you have an updated graphics card driver by checking the&amp;nbsp;manufacturer's website&amp;nbsp;(&lt;A href="https://knowledge.autodesk.com/support/autocad-lt/troubleshooting/caas/sfdcarticles/sfdcarticles/AutoCAD-LT-crashes-to-a-black-screen-in-Windows-10.html" target="_blank"&gt;Assign the correct Graphics Card&lt;/A&gt; - Step #8)&lt;/LI&gt;

&lt;LI&gt;Check the Operating System needed &amp;amp; the required updates by reviewing the&amp;nbsp;&lt;A href="https://knowledge.autodesk.com/support/system-requirements" target="_blank"&gt;system requirement for the software&amp;nbsp;&lt;/A&gt;&lt;/LI&gt;
&lt;LI&gt;Update your product with the latest service pack or Hotfixes by visiting the&amp;nbsp;&lt;A href="http://www.autodesk.com/" target="_blank"&gt;Autodesk website&lt;/A&gt;&amp;nbsp;or&amp;nbsp;&lt;A href="https://manage.autodesk.com/" target="_blank"&gt;account&lt;/A&gt;&lt;/LI&gt;
&lt;LI&gt;Reboot the computer&lt;/LI&gt;
&lt;LI&gt;In Windows Start, delete unnecessary items in the Windows Temp folder, but do not delete the Windows Temp folder itself. You can locate the Temp folder by entering %TEMP% in the Search bar of Windows Start&lt;/LI&gt;
&lt;LI&gt;Temporarily disable antivirus &amp;amp; firewall, use&amp;nbsp;Task Manager to "End Task" feature to end the anti-virus software or other items that could be running in the background&lt;/LI&gt;
&lt;LI&gt;If the above does not resolve the issue continue &amp;amp; try&amp;nbsp;&lt;A href="https://knowledge.autodesk.com/customer-service/download-install/remove-products/clean-uninstall" target="_blank"&gt;Clean Uninstall&lt;/A&gt;&amp;nbsp;of&amp;nbsp;the product and try a browser download via&amp;nbsp;&lt;A href="http://autodesk.creativevirtual15.com/autodesk/bot.html?isJSEnabled=1&amp;amp;businessArea=Root.Front%20Desk&amp;amp;startContext=Root.Front%20Desk" target="_blank"&gt;Autodesk Virtual Agent&lt;/A&gt;&amp;nbsp;(download&amp;nbsp;all the parts) and install the product again&lt;/LI&gt;

      <description>&lt;P&gt;I have a similar issue. When I start Revit 2018 for the first time after starting my computer I get this same "licensing system error 1".&lt;/P&gt;
&lt;P&gt;Pressing Ok closes Revit. Then Starting Revit again it works without licensing error.&lt;/P&gt;
&lt;P&gt;So you might to try to start it second time and see if that works.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;In my case it looks that it is too slow to get licensing data?&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Hello&amp;nbsp;@Anonymous,&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;I have tested Revit 2018 using the "Download Now" method from the Autodesk Account. The only issue I had was with Visual C++ 2015 in the install log. Try the steps below.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;STRONG&gt;&amp;nbsp;&lt;/STRONG&gt;&lt;/P&gt;
&lt;OL&gt;
&lt;LI&gt;Conduct a &lt;A href="https://knowledge.autodesk.com/customer-service/download-install/remove-products/clean-uninstall" target="_blank"&gt;Clean Uninstall&lt;/A&gt; of the program use &lt;A href="https://support.microsoft.com/en-us/help/17588/fix-problems-that-block-programs-from-being-installed-or-removed" target="_blank"&gt;MSfixitTool&lt;/A&gt; to complete the uninstall&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;Log in as an Administrator&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;Empty your TEMP folder. To open the TEMP folder, type %TEMP% in the address bar of Windows Start Menu and hit Enter&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;Temporarily disable your Antivirus software&amp;nbsp;&amp;amp; Firewall&lt;/LI&gt;
&lt;LI&gt;Temporarily disable UAC:&amp;nbsp;&amp;nbsp;&lt;A href="http://windows.microsoft.com/en-ca/windows7/turn-user-account-control-on-or-off" target="_blank"&gt;Windows 7&lt;/A&gt;&amp;nbsp;,&amp;nbsp;&lt;A href="http://winaero.com/blog/how-to-turn-off-and-disable-uac-in-windows-10/" target="_blank"&gt;Windows 10&lt;/A&gt;&amp;nbsp;&lt;/LI&gt;
&lt;LI&gt;&lt;A href="https://knowledge.autodesk.com/customer-service/download-install/download/about-download-methods/browser-download-method-for-autodesk-account" target="_blank"&gt;Download from Autodesk Account&lt;/A&gt;&amp;nbsp;or&amp;nbsp;via the&amp;nbsp;&lt;A href="http://autodesk.creativevirtual15.com/autodesk/bot.html?isJSEnabled=1&amp;amp;businessArea=Root.Front%20Desk&amp;amp;startContext=Root.Front%20Desk" target="_blank"&gt;Autodesk Virtual Agent&lt;/A&gt;&amp;nbsp;(download&amp;nbsp;all the parts)&lt;/LI&gt;
&lt;/OL&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;

      <description>&lt;P&gt;Dear Natasha,&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I'm sorry but Visual ++ 2012 and 2013 are no longer available.&lt;/P&gt;&lt;P&gt;I tried to start Revit 2018 without these but Licensing Error 1 still remains.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Maybe this is the same reason why Revit 2017 is no longer starting too?&lt;/P&gt;&lt;P&gt;Any advice?&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Thanks,&lt;/P&gt;&lt;P&gt;Bart&lt;/P&gt;</description>

      <description>&lt;P&gt;Hello&amp;nbsp;&lt;a href="https://forums.autodesk.com/t5/user/viewprofilepage/user-id/2500771"&gt;@Daniel_Voinkov&lt;/a&gt;,&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Try this link instead and conduct the same steps. &lt;A title="The latest supported Visual C++ downloads" href="https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads" target="_self"&gt;The latest supported Visual C++ downloads&lt;/A&gt;. If this does not resolve it try the following steps:&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;OL&gt;
&lt;LI&gt;Make sure you have an updated graphics card driver by checking the&amp;nbsp;manufacturer's website&amp;nbsp;(&lt;A href="https://knowledge.autodesk.com/support/autocad-lt/troubleshooting/caas/sfdcarticles/sfdcarticles/AutoCAD-LT-crashes-to-a-black-screen-in-Windows-10.html" target="_blank"&gt;Assign the correct Graphics Card&lt;/A&gt; - Step #8)&lt;/LI&gt;

&lt;LI&gt;Check the Operating System needed &amp;amp; the required updates by reviewing the&amp;nbsp;&lt;A href="https://knowledge.autodesk.com/support/system-requirements" target="_blank"&gt;system requirement for the software&amp;nbsp;&lt;/A&gt;&lt;/LI&gt;
&lt;LI&gt;Update your product with the latest service pack or Hotfixes by visiting the&amp;nbsp;&lt;A href="http://www.autodesk.com/" target="_blank"&gt;Autodesk website&lt;/A&gt;&amp;nbsp;or&amp;nbsp;&lt;A href="https://manage.autodesk.com/" target="_blank"&gt;account&lt;/A&gt;&lt;/LI&gt;
&lt;LI&gt;Reboot the computer&lt;/LI&gt;
&lt;LI&gt;In Windows Start, delete unnecessary items in the Windows Temp folder, but do not delete the Windows Temp folder itself. You can locate the Temp folder by entering %TEMP% in the Search bar of Windows Start&lt;/LI&gt;
&lt;LI&gt;Temporarily disable antivirus &amp;amp; firewall, use&amp;nbsp;Task Manager to "End Task" feature to end the anti-virus software or other items that could be running in the background&lt;/LI&gt;
&lt;LI&gt;If the above does not resolve the issue continue &amp;amp; try&amp;nbsp;&lt;A href="https://knowledge.autodesk.com/customer-service/download-install/remove-products/clean-uninstall" target="_blank"&gt;Clean Uninstall&lt;/A&gt;&amp;nbsp;of&amp;nbsp;the product and try a browser download via&amp;nbsp;&lt;A href="http://autodesk.creativevirtual15.com/autodesk/bot.html?isJSEnabled=1&amp;amp;businessArea=Root.Front%20Desk&amp;amp;startContext=Root.Front%20Desk" target="_blank"&gt;Autodesk Virtual Agent&lt;/A&gt;&amp;nbsp;(download&amp;nbsp;all the parts) and install the product again&lt;/LI&gt;
&lt;/OL&gt;

      <description>Hi Natasha,&lt;BR /&gt;&lt;BR /&gt;I tried all the other tips you gave and nothing worked.&lt;BR /&gt;By accident I found out that the mscvcp110.dll en msvcr110.dll were missing.&lt;BR /&gt;Replacing these files solved the problem.&lt;BR /&gt;&lt;BR /&gt;Greetings,&lt;BR /&gt;Bart&lt;BR /&gt;&lt;BR /&gt;</description>

      <description>&lt;P&gt;Hi All,&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I'm having the exact same problem, but when I checked the solutions under the Revit 2017 board, I found that my FLEXnet folder was empty, I'd imagine that means no licence file is being generated? It doesn't even give me the option to put a licence serial number in&lt;/P&gt;</description>

      <description>&lt;P&gt;Just to follow up, you have to reinstall the full suite of Visual C++ Redist, use the installer tool on majorgeeks, took 5min and fixed everything&lt;/P&gt;</description>
