Hello,

It seems like you're encountering a challenging issue with Trados Studio 2024 on a Parallels virtual machine. Let me guide you through some steps to help resolve this problem:

### Step 1: Verify Windows Updates

- Ensure that your Windows 11 virtual machine is fully updated. Go to **Settings > Update & Security > Windows Update** and click **Check for updates**. Install all available updates and restart the VM. Repeat this process until no further updates are available.

### Step 2: Repair Trados Studio Installation

- Open the **Control Panel** in Windows.

- Navigate to **Programs > Programs and Features**.

- Locate **Trados Studio 2024** in the list, right-click, and select **Repair**.

- Restart the VM after the repair process is complete.

### Step 3: Check .NET Framework

- Confirm that .NET Framework 4.8 (or later) is installed:

 - Open **Control Panel > Programs > Turn Windows features on or off**.

 - Ensure that **.NET Framework 4.8** is checked. If not, enable it and restart the VM.

- If .NET Framework is already enabled, refresh it:

Hi Anna,

Have you tried allocating more RAM to your Windows 11 VM inside your Mac? You can do this in the Parallels settings somewhere. 

Hi Anna Gilham

You have a subscription for Trados Freelance - Annual Saver - which includes a support contract, please login to your Account Portal and click on Support and raise a ticket directly with the technical team so they can investigate this.

Best regards,

Anca 

Hi Michael, I did, yeah, but I only have a total of 8 RAM, so maybe that is the issue. Thank you for your suggestion. Kindly, Anna

Great, thank you I will do that.

PS: I agree with Anna: ask RWS support! However, I also asked Claude, which I use a lot in my Supervertaler development with Trados, and it said the following (maybe useful):

A few things to try, roughly in order:

1. Read the actual Trados log (not Event Viewer). Open the newest file in %AppData%\Trados\Trados Studio\Logs\ after a crash and look at the last FATAL/ERROR line – it names the real cause.
2. Turn off 3D acceleration in Parallels. In the VM's settings → Hardware → Graphics, untick 3D acceleration. The "Initializing Views" stage is where Trados renders its UI, and in a VM the virtual GPU is a common cause of crashes there. This is a reversible checkbox on the Mac side – no Windows changes needed.
3. Delete plugincache.xml in the Trados AppData folder – Studio rebuilds it on next launch.
4. Confirm .NET Framework 4.8 is installed (required by Trados 2024).
5. Raise a support ticket – your Freelance Annual Saver subscription includes a support contract, via the Account Portal.

Optional (only if step 2 doesn't help): disable WPF hardware acceleration via the registry. In regedit, set HKEY_CURRENT_USER\SOFTWARE\Microsoft\Avalon.Graphics\DisableHWAcceleration to a DWORD of 1, then reboot. Why it's optional and last: it does the same job as step 2 (forces software rendering) but from inside Windows, and it applies to every WPF app under your user account, not just Trados – so it's broader than needed. Step 2 achieves the same fix more surgically and without editing the registry, so try that first. The registry key is fully reversible (set it back to 0 or delete it).
