Okay so I read this -
http://halo.wikia.com/wiki/Halo:_PC_%28Linux%29
Well I am running Slackware 13 and am trying to get it to work but the install doesn't even let me select any of the buttons.. Help? The options to click are all in text.

Actually the problem with wine is it doesn't check dependencies. Use "playonlinux". PLAYONLINUX is works using wine. the advantage of using playonlinux is ... It automatically checks for dependencies.
the list of games it supports are .. see this link

I'll definitely check that out Thanks

[edit] Okay so I downloaded it and it brought up this error
I just installed wxPython and it still doesn't work.

which way you are trying to install ?

for -- .tar.gz files :

You just have to extract these file and run "./playonlinux". PlayOnLinux is written in python and, so you have nothing to build.

PlayOnLinux : PlayOnLinux_3.7.3.tar.gz

Yep that's exactly what I did, it brings up that error when I try to run it.

Actually I installed playonlinux from my package manager (YAST). but when it comes to compiling from source, we face problems with dependencies. Now playonlinux needs wxpython as per your error message.

You can download wxpython from linuxpackages or if you prefer to compile from source, get it from the wxpython website.

I installed wxPython a few times and even confirmed that it is in fact installed. I'm retrying using Slackbuilds.org. I'll try LinuxPackages.net too if it doesn't work Thanks

[edit] Okay try installing it with Slackbuilds and it works now

lol, I got playonlinux working and finally got that to find my drive BUUUT it does the same exact thing. The main screen loads and than I can't click any of the buttons. Any ideas?

* The installer will not run without mfc42.dll, so download the file from here and extract the file to your /home/<yourname>/.wine/drive_c/windows/system32 directory

* Insert your Halo cd, and unless you installed by using the add/remove program, right click on setup.exe and click Properties. Click on Open with, and click +ADD. Click Use a custom command, and type "wine" (without quote marks) and then okay. Make sure wine is selected, and click okay. You can now double click on any .exe files to run them.

* Double click on Setup.exe in the cd directory.

* Then run the installer as you would on Windows, but don't select Express install, as that will cause problems. The installer may have several error messages, but these can be safely ignored, the game will install correctly. Click restart at the end of the installer (it won't actually restart your system)

Before proceeding with the installing of Halo make sure you have 3D hardware acceleration activated.

Yeah I have mfc42.dll but it still doesn't work. I just can't *click* the button to install. It's just text and not a button.

I can't proceed with the install, the button to click to install is simply text and not a button. Also earlier (not in Halo though) I saw a message that said I didn't but I thought I did. How do I check? Sorry, a bit of a noob with wine.

Hm... I looked at this
And by that, I have NVIDIA drivers, it should be enabled... Plus I have played a lot of 3D games including Nexuiz and I have OpenGL enabled on AlephOne though not sure if that counts. I also have an OpenGL based GPU for ePSXe, hm...

Hey just letting you guys know, I got it working All I did was install it in a Virual Machine than copy the files over to the main computer.

ok thats good. Now do a single step. Make this thread "SOLVED". this option available at the "thread tools" which is just above the post #1

Cool Marked solved
