It installs fine on a test account, even as a Standard User. Maybe that's not what you meant.
The account in question was migrated from a Vista install (with Windows Easy Transfer), and Onedrive was installed on it on Vista. What I suspect is that there is something left in the registry (or somewhere else) from that old install that is hanging up the new install. But what?!
I tried the install authenticating with the built-in administrator, but still no go.
Go to Control Panel - Programs and Features and uninstall if there is any "Microsoft OneDrive" entry.
Maybe you are better off with a new account, can get files from your current account and there shouldn't be any problems.
There's definitely no entry in Programs and Features. At this point you're probably right - the chase is more complicated than it's worth. Thanks for all your suggestions! They were educational for me even though the problem has proven too elusive to track down.
You can use Windows Easy Transfer - Transfer To & From Computers to make the change.
I just got it! It turned out to be a registry permissions issue as we had suspected. The key in question is:
HKEY_CURRENT_USER\Software\Classes\CLSID
I had to give my user Full Control on this key and then Onedrive installed without a hitch! I was assuming that the SubInAcl process that you recommended, Gokay would have dealt with this, but apparently not. I take no credit for ferreting this out. I found it in the responses to this post:

None of the suggestions here or in several other forums I've visited solved the problem. Running Windows 7 Pro, 64-bit, SP1 + all updates, Office 365/16 Home. Tried install of latest OneDrive version, failed; uninstalled existing OneDrive in Control Panel, failed; tried running as Administrator, failed; deleted registry key for OneDrive, failed; changed the installer's compatibility property to XP SP3, failed; I give up.
I gave up too.
Mine installed just fine. But performance was poor. Many uploads to OneDrive would fail. Retry. Fail. Retry. Fail. Retry. Finally works.
Next file, same thing. Fail, retry, fail, retry.
Small files seemed to work okay. But anything bigger than a few MB gave trouble. So I gave up.
I moved to Google Drive. It works, and it works, and it works. Problem solved.
