Before Starting First of all Double Click on .theme pack if you are able to change theme then doesn't need to goto next step.
If not installing theme with above step then try this. For Install third party themes you just need to patch three files located in "C:\Windows\System"
uxtheme.dll, themeui.dll, themeservice.dll these are the files you have to patch but before proceeding next step make sure to Backup these files.
For Patching those 3 files you need Universal Theme Patcher created by deepxw that works with Windows XP SP2 SP3/2003/2008/Vista SP1 SP2/Windows 7, 32bit(x86)/64bit(x64).This tool only patches files it won't run process in background.
You need to give an administrator privileges so Right Click on Patcher and select "Run as Administrator" then patsh those three files.
After "Patch Successful" message put your theme files into Windows theme folder (C:\Windows\Resources\Themes). To do this just copy one Folder of theme and .theme file. After copying Double Click on .theme file that's It!!!
