I had this issue with 2017 so installed 2018. Am getting the same issue and have tried the steps above. I installed as admin. I had a PreBootstrapper error and installed using the steps in this post -
This allowed me to install. However I’m now getting an error whenever I try to export (same one I had in 2017)
I’ve tried doing a blank PDF with a short name saved to the desktop but still no dice! Does anyone have any suggestions. Checked my graphics driver which is up to date - am at a loss for what to do. I have clients waiting for drawings and can’t put them off any longer. Am exporting Jpgs for now and stitching together into PDFs but the quality is poor and its just not a great alternative. Any help much appreciated.
Thanks
Sam
