Did you have any errors during the install?
I had a machine have errors about not being able to close Windows Explorer, on this machine I uninstalled, re-booted, and then it was OK.
No problems with install or IV. Inventor actually seems faster.

A 1402 error indicates that you do not have permissions to write to a specific key in the registry. In the error it should tell you where it is trying to write to. You'll need to run regedit, find that key, Rt click go to permissions & ensure that Everyone has Full permission.
If that does not fix it then Set “Everyone” full permission to : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr

Install went fine on 64-bit, don't have any machines that run 32-bit anymore, so not sure there. Inventor seems a little faster, will know more after today.

I no longer have a record of the specific path that was mentioned, but 2013 is the first version in which this has happened (all the way back to 5.3). The administrator account that I am using to install the SP is the same one I used for installing 2013 RTM, and therefore the account which created that section of registry. It works on some machines, or perhaps in some circumstances, not on others. But I have uninstalled and reinstalled from an udated deployment with no issues on the machines that threw the error.
