Frequently Asked Questions
How can I use ArtRage 4 on Windows XP?ArtRage 4.5 does not support Windows XP. We have shifted the older ArtRage 4.0 build to an optional WinXP branch that you can find by following the steps below. This will allow you to continue to work with the XP compatible version.
To sign up to the WinXP option:
- Go to your Steam Library
- Right click on ArtRage 4
- Go to Properties
- Go to the Beta tab
- Opt into the WinXP Branch
Does ArtRage 4.5 Support Windows XP?
No. Unfortunately, Windows XP support had to be dropped in the 4.5 update, as it was not capable of supporting certain upgraded features. ArtRage 4.5 supports Vista, Windows 7, Windows 8/8.1, and Windows 10 (as well as Mac OS 10.6 and later).
Microsoft provided support for Windows XP for the past 12 years. However, as of April 8, 2014, support and updates for Windows XP are no longer available. Accordingly later hardware/software features also become unsupported that is used in ArtRage 4.5, however we will still provide you with a different copy that will work with Windows XP due to this reason.
We have a download of the last supported version, ArtRage 4.0.6, available in the Member Area.
If you own an ArtRage 4.5 licence, you can register the serial there and choose to download the older version instead. You are then also able to download ArtRage 4.5, if you upgrade to a supported Operating System (such as Windows 7, 8/8.1, or 10).
This option will also be available for Steam users through Steam.
Can’t install on Windows and getting “Disk1.cab has an invalid digital signature”
If you are getting the following error:
A file that is required cannot be installed because the cabinet file C:\Documents and Settings\…\Application Data\Ambient Design\ArtRage Studio Pro\install\disk1.cab has an invalid digital signature. This may indicate that the cabinet file is corrupt.
This is usually a Windows XP or Vista issue and has been occurring with increasing frequency since Microsoft stopped supporting these operating systems, but also appears on later versions of Windows.
It is due to either the relevant digital certificates not being installed on your computer or a deeper problem on your system. Unfortunately the certificate and verification system are entirely handled by Microsoft, so we cannot help you fix this problem directly, only offer suggestions.
How to install ArtRage when you get this error
If you know that your computer is out of date, installing Windows updates may solve this problem. If this does not work, try the workarounds below.
Option 1: Copy the ArtRage files from another computer
The easiest way around it is generally to download ArtRage on a different computer, then save the file to a USB drive and use that to copy it to the computer that you want to install ArtRage to.
You can either install directly to a USB (choosing a location is an option during the install process) or install normally and then find the files by going to:
C: Drive > Program Files (or Program Files (x86) – it can be installed under either) > Ambient Design > ArtRage [Edition Name/Number]
Copy the entire folder and transfer it to the computer that you want ArtRage on.
Option 2: Turn off digital signature checking
The core of the problem is that your Windows installation is unable to contact the certificate provider that can verify the installer’s security certificate. This can happen for a number of reasons and it can be really hard to track down the cause. There are two things that you can try easily that may help:
If your Windows XP machine is unable to connect to the internet, Windows cannot verify the validity of the digital signature in the file. Make sure your machine can connect.
Windows requires that secure installers be verified before installation, which in turn requires that the OS is able to talk to the certificate provider to double check the certificate in the installer file. If your XP machine is unable to connect to the internet, or unable to contact the certificate provider, Windows will generate the error you see.
You can tell Windows not to check the digital signature of the file by turning on ‘Allow software to run or install even if the signature is invalid’ in the Internet Options section of your Control Panel or from Internet Explorer.
- Locate the Internet Options panel which is either in your Control Panel or accessible from Internet Explorer.
- Select the Advanced tab and scroll down the list of advanced options until you find the Security section.
- Look for an item called (or similar to) ‘Allow software to run or install even if the signature is invalid’. Turn that ON.
- Okay the panel.
What this does is tell Windows that the certificate of an application doesn’t need to be checked before installation. This can fix the problem you see, but in some cases Windows ignores that option and checks anyway.
Important: Turning this option off reduces your computer security – If it works for installing ArtRage you may want to turn it back on afterwards.
Option 3: Install the digital signature manually
It is also possible to manually install a verification certificate to allow Windows to verify the file offline, but this is quite complex. You would have to download or copy the certificate from elsewhere to do this.
This option is a lot more complicated and varies with each individual computer, so we may not be able to help directly. You need to:
- Find the certificate number in the error message (they are all different)
- Search online for the file to download (it may be available on Microsoft’s websites somewhere. If not, you will have to use your own judgement – people with the same problem may have shared it. Please be cautious when downloading mystery files from the internet).
Once you have located the correct file, see this articles for step by step assistance installing it to your computer:
Once you’ve updated your certificate, you should be able to run the ArtRage installer normally.
