Type library is not automatically created by CC2020 installation. Error 104705: Unable to load Adobe InDesign Type Library (Version 1.0)
Extensions and scripts halting or crashing after installing CC2020, due to a missing type library.
Our customers report errors after updating to CC2020, and I got the same error when I tried. Our script make a halt at a DoScript call, with this error: 104705: Unable to load Adobe InDesign Type Library (Version 1.0)
After starting InDesign CC2020 "AS ADMINISTRATOR", a missing type library is obviously created: the message and error disappears after doing that once.
It was not enough for my user just to have administrator privileges on my computer and in the domain, I had to explicitly start InDesign as Administrator.
I found the answer here: https://community.adobe.com/t5/indesign/doscript-error-unable-to-load-adobe-indesign-type-library-version-1-0/m-p/11335921?page=1#M197052
This needs to be fixed in the Adobe installation package for CC2020. Otherwise many script end-user will have to call support and have someone to start InDesign as administrator for them (in case they are not allowed to do that themselves) – it's not obvious to an end user what to do at all when this error occurs.
The fix of the issue is now available in the latest InDesign 2020.1.2(v22.214.171.124). We recommend you upgrade to the latest version for the fix.
If you are unable to see the update, go to the Creative Cloud application and click on the context menu on the top right and click on Check for App Updates.
