Just as with files, registry keys have permissions and you can be locked
out of a registry key without permission, even if you are an admin. Of
course, as an admin, you can change the key permissions to allow access,
but which key(s)? Only ADP knows.

You might be able to save yourself some time by trying to install the
software when logged on as each account that will use it. That trick
often works for game software, it might work in your case, otherwise,
you have to find the vendor keys (usually in HKLM\Software\vendor\app,
where "vendor" and "app" depend on your vendor and the application) and
then use the Permissions... menu item in regedit.exe to change the key
permissions. You likely can fix the problem by adding the Administrators
group with full permission, if you find that only the Administrator
account has write privilege.
