You download AxCMS.net (or AxCMS.net Premium Template Project) and run the Installer. But it throws errors.
One possible cause: On Windows versions after XP (e.g. Vista, Windows 7 and Windows Server 2008 - all with UAC) you have to run the installer in administrator mode. If you just run the installer normally, it will fail because of not having needed administrator permissions.
Another one possible cause could occure when you did not pass preinstall steps described here
If this is the case, run the installer once again as administrator. In Windows Explorer right-click on the installer and select "Run as administrator" (or hold Ctrl+Shift pressed while clicking on the exe-file).
If the isntaller (the exe file) already unzipped the files, it is enough to run install.bat from the application directory (which is C:\Projects\AxCMS_Sample or C:\Projects\AxCMS_PremiumSample).
For other possible problems during installation see Troubleshooting.
