After upgrading to 8.3 (from 7.6.1) I noticed that some php site was not working (but Plesk was) According to Plesk php has not been installed. I ran the installer again and it showed that PHP was installed but PHP5 not. I selected PHP5 and clicked next to install the component. After 24 hours the setup is still at "Applying security for C:\Program Files\SWSoft\Plesk\admin.....0 Minutes remaining" I cancelled the setup but now I still don't have a way for clients to select their PHP version. I need a way to run PHP4 & 5 simultaneously on the server and be able to select my version from Plesk - according to the documentation this is possible. I found a few post that says that you can install both version manually and add a reg key to distinguish the php.ini files and then Plesk would pickup both versions. I am not to clued up on PHP and would rather the installer do it. Please help.
