Autodetect Flashpoint-Folder for Installer

[Flumon 0]

Hey guys,

I'm looking for a way to revive the flashpoint-spirit of some of my friends. At Lan-Parties, when i suggest to play flashpoint, some of the guys say that flashpoint has too old graphics and is always the same. Then I tell that there are TONS OF GREAT ADDONS and you simply have to install some to highly improve gameplay. Manually installing is very time intensive but what about a SIMPLE INSTALLER?!

Then I grabbed Nullsofts Install-System(v2) and made a good installer with just the right addons and missions. Now I want the installer to autodetect the user's flashpoint-folder to which the addons/missions will be installed.

On Winterofp.com you can download a similar installer that is just like i want mine and it CAN DETECT the Flashpoint Folder.

I think it must be something like that

InstallDir "$PROGRAMFILES\Flashpoint"

or

InstallDir "$OFP"

Can anybody help me please?

AFAIK, the only way to detect the OFP directory is by reading the registry key containing it. I don't know the installer you're using, but e.g. Installshield has the ability to read out this registry key and then use it to install addons in the proper directory.

NSIS is a great install system I like it.

Here's part of the code I used

Quote[/b] ]Function .onInit

ReadRegStr $INSTDIR HKLM "SOFTWARE\Codemasters\Flashpoint Resistance" "MAIN"

IfErrors 0 end

MessageBox MB_YESNO "Game is notinstalled. Continue ?" IDYES yes IDNO no

yes:

MessageBox MB_OK "You will have to specify OFP directory"

Goto End

no:

Abort

end:

FunctionEnd

InstallDir "$INSTDIR"
