Curse Client v4 (PC) - Early Access Beta

I am very proud to announce the official launch of Curse Client v4 Early Access Beta!

The New Client is Born

After the launch of Curse Client 3.0, we began taking notes on the most frequent user requests, complaints, and general feedback. The result of this feedback is version 4. In development since May, version 4 of the Curse Client has been redesigned from the ground up. Written in C# and utilizing Microsoft WPF technology, the Curse Client now sports a modern user interface and an entirely new set of features.

  • AddonSync - Keep your addons in sync across multiple game installs and computers. Backup and restore addon settings, automatically.
  • UI Wizard - Create your own UI packs, and share them with your friends.
  • Addon Icons - All addons now have icons for better identification and visual feedback.
  • Integrated Bug Reporting - To assist authors in identifying issues and handling feature requests, the new Curse Client now includes an integrated bug reporting module.
  • New Scanning Technology - Checking for addon updates now only takes a couple of seconds, and uses a fraction of the CPU as version 3.
  • Small Memory Footprint - The new client has been optimized to fit within a tiny 1 to 3 megabyte footprint (when idle) and 1 megabyte when trayed.
  • Better Customization - Choose the information you want to see in your addons list, the number of simultaneous downloads and even your UI theme (two in beta, with more to come).
  • Better Searching - Search addons by name, category and author, instantly.
  • Better Security - The Curse Client is now digitally signed by VeriSign to ensure authenticity. Additionally, all client-to-server communication has been secured with HTTPS-level encryption.

Below are instructions for how you can get into the early access beta, as well as screenshots showcasing the new client.

A native, Cocoa-based Mac client has also been in development, and will soon be entering beta.

Installing the Beta

Simply download the installer from and run it. The installer will verify a compatible version of .Net is on your computer, and update it if necessary. Depending on what version of .Net is installed on your computer, this process can take anywhere from 30 seconds to 5 minutes.

How to Report Bugs & Feedback

Please report all bugs using the integrated bug reporting tool. This will automatically include a snapshot of the Curse Client log data, as well as your operating system information. We're excited to hear what you think about the new Curse Client.

    It would be nice if there was a linux client. Or something better than clicking on 30 links to update my addons every weeks. No V3 doesn't work even with IE6 installed using winetricks.

    Looks like I may have to set up a windows virtual machine and share the folder with the guest and tell the updater to use that. Seems like a lot of overkill for something that could be done with a bit of rate limiting and connection tracking (see contrack in iptables). A premium client could be offered using something like ssh port forwarding to auth the user.

    I'm betting posting about a linux client is a bit of a no-no guessing by previous posts for older versions. Also if this was a java app it would be at least as portable (and the code would not be visible).

    I started Curse client ver. 4.0.14 today and it told me it was updating to ver. 4.0.16. after a few seconds a small window popped up quickly, to quick to read, and then I was back on my desk top. When i try to run it now nothing happens. If i try to reinstall it tells me that there is an issue but only gives me an ok button. It also will not uninstall.

    Looks like it will be very nice. I have to second (or third) the questions about a native linux client, or at least something that is compatible with wine.

    @aigarius: the client won't run under mono. It's using some techs that mono doesn't support currently.

    @grayal: i'll forward this

    but just to remind everyone. Posting feedback/questions in the bug tracker will help much more than posting here about it. & Adminstrator

    The 'automatic' installer fails spectacularly on Linux. Just give us a simple archive that can be unpacked into a folder and have it work there. You can even test how it will work by using the Windows version of Mono - the open source .Net implementation that works in Win, Lin and Mac.

    This client do not work on Windows XP without administrator rights! The setup program did not ask the user on installing of the autostart process!

    I installed The program last night and it worked perfectly fine. then when i started my comp back up today it wouldn't start the client, i watched my processes over the task manager and it wont even start a process or anything and if it does the process instantly disappears. I even tried to reinstall it but that didn't help either.

    anyone know what the problem could be?
