FAQ: Missing Areas of the User Interface in Discovery Live

When launching Discovery Live, one or more areas/functions are missing

• The Discovery Live interface and toolbars may appear to be the same as Discovery SpaceClaim
• Some toolbars or buttons may be missing
• Discovery Live simulation functions may not be accessible
• The Discovery Live design window may be gray or empty
• Legend from the Discovery Live interface is missing.

 

The 5 most common causes of this problem are as follow:

1. The graphics card does not meet the minimum hardware requirements to run Discovery Live.

2. The graphics card drivers are outdated.  The latest drivers can be found here.

3. Check if there is DLL file nvcuda.dll in Discovery installation directory and delete it.  It is typically in C:Program FilesANSYS Incv193scdm .
Do Not Delete LLD file: nvcuda.LLD

4. Critical files or changes to the PC that take place during the installation process are blocked by third party antivirus programs or Windows Defender.

To resolve this problem:

1. Uninstall all Discovery products
2. Temporarily disable any antivirus, antimalware, and/or Windows Defender functions
3. Ensure that you have full administrator privileges on the PC
4. Right click the Discovery installer, select Run as Administrator, and follow the prompts to complete the installation

The installation process will need to be allowed to make changes to the Windows Registry and some system folders in Windows.

You may need to contact your IT administrator if you do not have sufficient privileges to make the necessary changes.

5. If the scale/text size is set to more than 100% in computer Display Settings, it may result in Legend not showing up in the Discovery Live interface. Setting the scale/text size back to 100% resolves the issue.

Below are the steps to change the scale/text size:

1. RIght click on your desktop and select “Display Settings”.
2. Set “Change the size of text, apps and other items” as “100% (Recommended)”. See below snapshot for reference. This option for changing the text size may be different in different machines. For example, there could be a slider for adjusting the % of text size instead of a dropdown. In any case, the requirement is to set the value as 100%.
3. After changing the text size, restart your PC.
