Datasmith for 3ds Max 2020 won't install

I am having trouble installing new driver for datasmithing for 3ds Max 2020. When I try to install 5_1_1 I get an error saying “the feature you are trying to use is on a network resource that is unavailable”. I can not click browse to find UnrealDatasmithMaxExporter_4_22_E2.msi, because it does not exist on my computer any more.
I do see the old Datasmithing for 3ds Max installed when I search programs, but when I click to uninstall the old version, I still get the same error message, and when I click the “OK” button I get another error saying the file path does not exist.
I went into Task manager and ended tasks for anything Autodesk and Epic Games related. I searched the C: drive for datasmith to get a file path to remove the old version and did not have any luck. Uninstaller still looks for old version and there is no way for it to ignore that it doesn’t exist anymore.
What are the next steps to remove the old driver and install the new one? Please help, and thank you in advance.
