Inventor will not let me run installer

[Anonymous]

Trying to download the 2021 student version and every time I try to install Inventor I get this message. I've cleared all the temp files and still, it doesn't want to install.

Hi @Anonymous,

Since you've cleared the temp folder the next step would be to change the system temp folder temporarily, instructions of which can be found here: https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/Installation-error-referencing-SecondRun-and-FirstRunThreadId.html
