This is a merge of my installer code into John's Installer. It looks ok for me but requires broader testing, so here you go.
I had to tweak a few lines in the installer itself to get component selection working like my own installer, and the actual install process of installing Chrome and copying the profile etc is the same as in the previous installer I used.
As for new features in the installer itself, I don't really have any except that I updated the download links in the installer to the latest Chrome versions.
Oh yeah and the components page is only in English, I dunno what shows up in other languages, sorry. >_>
NOTE: This installer contains official PortableApps.com logo and branding generated by the PortableApps.comInstaller wizard. Please note that this is not [yet] an official PA.com app and is not [yet] supported by PA.com. Just by me.
NOTE #2: If you wish to compile this installer you will need the nsexec and nsisdl plugins, which come with NSIS IIRC but aren't included in the PortableApps.comInstaller package.
PS John: Please have the installer creator wizard prompt you if it's going to overwrite files in Other\Source. I almost lost all my installer code.
PPS John: Any feedback on what would be needed to make this "front page" material would be welcome. I didn't see a download feature (I think you mentioned one a few weeks ago) so I just kept using nsisdl. As well the user can select from a number of versions and the complex steps requires that I write my own Section code (you may wish to include support for additional/custom Sections in a future version of PAI).
