Well, for all those that have looked at this post & didn't know the answer to give me, I solved the issue myself!
The problem was with Upgrading from RC 7100 to RTM build 7260 & not with the 7260 build at all...
Once I did this ALL of the added features including Internet TV were all there & working correctly...
So DON'T upgrade from RC 7100 if you want Media Center to work correctly but instead upgrade from 7229 instead!
To do this with the SoLoR ISO do this & it works perfectly as I just got done doing it!
SoLoR ISO used:
Windows 7 Ultimate x86 build 7260 RTM branch by SoLoR _working_ Upgrade Method: 7229 to 7260
1. uncompress your iso to x:\new7260
2. open sources\cversion.ini with notepad.
3. modify to read:
[HostBuild]
MinClient=7260.0
MinServer=7100.0
4. Open properties on Setup.exe (change to x Run as Admin - change to compatible mode Vista SP2)
6. Apply and exit
7. Open x:\new7260 click setup.exe to start Upgrade process and when ask enter any old legit RC Key.
I don't remember who posted this & I'm not taking credit for this method, only posting that it DOES WORK Flawlessly!!!
