For example, I want to install EP prj template: AxWebProject.zip

1. Copy AxWebProject.zip zip file into this folder

   C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ProjectTemplates\Web\CSharp\1033

2. Extract this zip file into one folder, and rename it to AxWebProject.zip

   Be care it must be same as zip file name, must append .zip postfix.

3. Move this folder into this folder:

   C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ProjectTemplatesCache\Web\CSharp\1033

4. Sometimes, maybe these cmd can be useful.

devenv.exe /setup

devenv.exe /installvstemplates
