Installation False Complete - Very Frustrating

Bump - Can someone please get back to me on this?

Thanks.

Dear RegalPug,

Where are you located in the world?

USA 

(EDIT (Crin: Change your post. That was too much information. General region/country is enough. Don't post personal information on a public forum)

Thanks - any additional information you need on it?

Check if you have any _Installer folder in programs\Origin_Games\thesims4, delete them and try again.

Still nothing. Found the _Installer in that section of the Program Files, deleted it, but still when I go into Origin it only gives me the prompt to Install and then says that it's complete, but continues to just say "Install".

Try this workaround

No avail from this either - when I go into RegEdit there is no "Wow6432Node" when I go into the SOFTWARE folder. Any thoughts?

This is extremely frustrating.

Could you post your Computer's DxDiag?
