Ran all other updates they all installed no problem. Ran DP update six hours later still no install. I will try delete DP installer and run thur 3C again. Or, run DP install outside of 3C.

Red4Con1 - as Noel says (see above) the update is just the installer;  so if it works already for you, you'll gain nothing from the update (if I understand correctly).
 
Does this update overcome the issue where you need to run DPro as admin?

The only time DimPro needs to run as admin is the first time when registering the product.

The update to Dimension is just the installer. It basically unifies the installer for all languages and I believe fixes some issues with registration. However if you already have it installed there is no need to download it again.
The same applies to sound center. 

Would have been a useful piece of information to have several hours ago before wasting time on the download. It's hard to figure this out without some additional info especially when the version number is newer than what you have installed.

When I try to delete DP installer I found out I have a few instances running. After stopping them
I run installer outside of CC it ran thur without problem until it ask for the code I give it to them then they say no go.
I run inside CC and still at the end of the install it just hang there two and a half hours so far.
