I have a subscription to Autocad LT 2020 on my Windows 10 AMD based workstation. Today I received an email from Autodesk saying that I was eligible to upgrade to version 2021. I downloaded the installation file and extracted it to the correct folder. The installation gets to item 8 of 11 and then gives me an error message 1631 saying that my Windows Installer was not running. I checked my services folder and discovered that it was running. I tried several more times to download the files and install to no avail. I was told by an Autodesk tech on chat to download using my browser. Still nothing. I went on chat again and the second tech told me that I should wait a couple of days and try it again because everything has not synced up yet since I just received the email today. Does anyone have any ideas for me to try next? Thanks in advance.

I have this issue as well. I just tried to apply this solution. There are no "Null" values in that Registry Location. The only Autodesk entry I can find is named ADSK_CLM_WPAD_PROXY_CHECK and its value is set to FALSE. There is an entry called (Default) that says (value not set) but that is a system value that is in every registry location. Are there any other possible solutions?
I am getting the same error with the trial version, doesn't encourage me to pay for the actual product. I deleted all Autodesk software off my computer and tried again. Still not working. This is infuriating! Total loss of $$$ messing with this just to open one file.
