AutoDesk Inventor Installation Error 1920

Hello Everyone,
I have been unsuccessfully attempting to install the AutoDesk Inventor for this last two days. Halfway through the installation process, I run up to error 1920 that says I do not have the necessary privileges to start some system services. I fail to understand what might be causing the trouble. I am the lone user on this computer and of course, I have full access permissions. I attempted disabling my antivirus during the download and tried installing. But this failed to give the desired result. Next I tried installing all the windows updates and disabled all UAC as well. Now I restarted the machine and tried a fresh download and install. But this step too didn’t help me. I also tried run as administrator option although I am logged in as administrator but this effort too didn’t help to improve the situation any further. Please can somebody help me? Thanks and Regards.
