Alright kiddies, so I've successfully installed Arcanum on Vista Ultimate 64 bit. I'm running version 1074. Just to test it, I've been booting the game, letting it go through all the opening videos, starting a new game, and then closing it. I've been doing this as opposed to a full play-through because most people expressed the issue being within the first launch period. If Vista isn't fucking working for you, please follow my steps. If it still isn't working when I'm done, please hit yourself in the head with the pointing courner of your keyboard. If your keyboard lacks a suitably pointy courner, please try again with a different but similar object. Maybe your monitor? Anyway, onwards and upwards: If you install it, and it won't run, Uninstall it and Reinstall it. If this doesn't fix it, the first thing to ask yourself is, "Are you an administrator on the machine?" If you don't know the answer to this, please follow this steps to check: Click on the Start Button. Select Control Panel. Switch to Classic View. Select "User Accounts." It should, in the little bubble next to the flower picture that most likely symbolizes you accurately, say "username administrator password protected" If you'ren't an administrator, please get mommy and/or daddy to make you one. Are you an administrator? Will Arcanum still not boot for you? Alright then. Let's try attempt number two: Click the start button. Click "Computer." See the "path" bar at the top of that window? Let's click on that. Not the computer part, just to the right of it. At this point, it'll change to an actual path, and you want to change it to C:\Sierra\Arcanum If it tells you there's nothing there, try D:\Sierra\Arcanum . Now then, let's carry on with these unnecessary steps, shall we? See the little file called "Arcanum.exe" that has a gear symbol? Right click on that, and select properties. Switch to the "Compatibility" tab. Select "Run this program in compatability mode." Select "Windows XP SP2" And, while we're at it? Make sure that "run in 640x480 resolution" is checked, as well as "Run this program as administrator." If the box is greyed out, don't worry about it. It means that it already is. If this fails to solve your problem, I recommend the step involving the keyboard and your face a few more times, and then, once your vision is suitably blurry due to blood, post here, crying about the blood in your eyes, and the fact that Arcanum won't run. Please note: I did absolutely nothing to my install of Arcanum. It's a plain-Jane vanilla Arcanum. In case you think that, somehow, it's a difference in machine, below is what I installed it on. Also, if you read through this guide, and go "I don't know how to do this step" please find a friend/family member/someone you can sleep with that is technologically inclined, and get them to read through this and do it. I intend to update this as solutions are sorted out. Good luck, godspeed, and I'll kill the next person to make a thread about Vista. Something else of interest: I didn't do jack shit to make it run on my machine. I just installed it. This is for those whom somehow fail at that act. Windows 10: Please follow this link to a video on how to configure it for W10, running on the assumption you downloaded it from GOG (setup via disk would probably be the same, just with having to download the UAP). User Access Controls Thoughtful Disclaimer: Microsoft doesn't think it's wise to turn off UAC Since somebody asked, I thought I'd throw in a guide on how to remove UAC. It's rather simple. Follow these steps: 1. hold down the windows key and press 'r' 2. type 'msconfig' and press enter 3. select the 'tools' tab 4. scroll down until you find 'disable uac' 5. Here's the confusing part: with 'disable uac highlighted, press the 'launch' button 6. reboot WidowPC Sting 915 Intel Core 2 Duo 2.6GHz 2Gb of Ram Windows Vista Ultimate 64bit Dual 250Gb WD HD Since this is disabled on my machine, I'll tell you all how to do it: User Access Controls nerfing: When you're sitting at the desktop, press the "Ctrl" key and the "R" key. UAC will come up, and scream at you, but ignore it, and carry on. Type into the box that appear "Msconfig" Select the "tools" tab. Scroll down until you see "Disable UAC" Here's the confusing part. You want to LAUNCH Disable UAC. Having done this, you must now reboot your machine. When you log-in after the restart, it will ask you if you want to open "msconfig again." The wording is odd, but you want to select "Do not show this prompt or launch Msconfig."
