PHP Manager for IIS fails to install
I am trying to install PHP on IIS 8. Every time I start the PHP installation, PHP installs but I get the follow error: As Abhi says: fire up regedit.exe and change the decimal value of Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W3SVC\Parameters\MajorVersion from 10 (as set by Windows 10) to e.g. 8. Installer should work now. Afterwards, you can set the value back to 10 (or whatever value your Windows env. had at first). Tip : For quick navigation, paste the path Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W3SVC\Parameters into the address-bar of Registry
