My system info: Win XP SP2. Previously, I have Apache2.0.4X installed. Due to the lost of Uninstaller file, I removed all Apache info from Registry in order to be able to install a newer version.
After successfully removing previous version, I always get this alert "The system administrator has set policies to prevent this installation" whenever I click to install apache_2.0.55-win32-x86-no_ssl.msi
