Xampp directory mismatch

If you unzip the Xampp files (e.g. into c:\xampp) the installer doesn’t know where the installed files went.  You will see in the Xampp Control Panel Application (xampp-control.exe) a message “directory mismatch”.

This doesn’t matter for normal operation of Xampp, but if you try using the installer for Xampp add-ons (for example, Perl), you can’t proceed.  You can, however, simply use the .zip version of Perl, and manually install it in the c:\xampp folder (or whatever other folder you used).

There isn’t a file that I could find that stores the installation location.  The xampp-control only checks the Windows Registry. If you prefer to have the installation file recorded, use the following steps:Open the Windows Registry Editor (Start, Run, regedit)

Navigate to HKEY_LOCAL_MACHINE\SOFTWARE
Right-click on SOFTWARE and select New Key. Type XAMPP then click OK.  Right-click the XAMPP Key you just created, and select New, String Value. Name it Install_Dir (probably case sensitive!) then hit Enter. Double click this value and in the appropriate box, type the path of your current XAMPP installation (C:\xampp usually). Close the Registry Editor.

Restart the Xampp Control Panel and you’ll see the installation directory has been properly set.   You can now install your add-ons.
