Pinnacle Studio 16 won't load

Pinnacle Studio 16 fix for Windows 8.1.
Just replace the value of the registry key VersionNT stored in HKEY_LOCAL_MACHINE/Software/ Wow6432Node/Avid/Studio 2. Change value to 602 from 603 if VersionNT key is present.

*If there is no key VersionNT key present then choose create a new value and name it VersionNT then edit it and and add the value 602 to it.

Steps to make the change for those unfamiliar with these things

 First I recommend that you completely uninstall all of Pinnacle along with bonus packs in control  panel/uninstall a program, then restart your computer and perform a fresh install of Pinnacle Studio.  This will remove any prior patches and changes you've made. 

 DO NOT OPEN THE SOFTWARE PROGRAM after install and perform the following steps.  

 1- Move mouse to top right hand corner in Win 8.1 

 2- Select search and type run and hit enter 

 3-  At the bottom left a window will appear, type regedit and hit enter 

 4- Click yes to enter registry editor 

 5- Select HKEY_LOCAL_MACHINE 

 6-  Select software

 7-  Select Wow643node

 8-   Select Avid 

 9-  Select Studio 2 

 10- Now on the right you will see some Key items. If VersionNT is not listed then right click on that       page and select new string value. Now name that VersionNT. 

11-  Now right click on VersionNT and select modify

12-   Under Value Data enter 602  

13-   That’s it!

14.          Exit out of everything and restart your computer.
