3D Studio Max 9启动故障：卡在欢迎界面无法正常打开

Hey there, let’s work through this frustrating 3ds Max 9 issue on Windows 10 together. You mentioned this was fixed by installing DirectX 9 before, but it’s back even with DX9 installed—let’s break down your options:

Should You Reinstall DirectX 9? #

Absolutely, reinstalling DirectX 9 is still a solid first step here. 3ds Max 9 is a legacy app that relies heavily on DX9 components, and even if you have it installed, system updates, file corruption, or overwritten files can break things. Since this worked for you before, it’s worth refreshing those DX9 files first.

How to Refresh/Reinstall DirectX 9 on Windows 10 #

Windows 10 doesn’t let you fully uninstall DirectX 9 (it’s integrated into the system for legacy app support), but you can effectively repair or refresh it:

• Grab the official DirectX End-User Runtime Web Installer. Run it as administrator—it will scan for missing/corrupted DX9 files and replace them automatically.
• For a more thorough overwrite, open Command Prompt as admin, navigate to the folder where you saved the installer, and run:

  dxwebsetup.exe /q /c
  

  This command performs a quiet, full installation that ensures all DX9 components are fresh and intact.
• If you want to try a full cleanup first, third-party tools like DirectX Uninstaller exist. Note: This carries some risk (it can break other old games/apps that use DX9), so back up your system before using it.

Alternative Fixes If Reinstalling DX9 Doesn’t Work #

If the issue persists after refreshing DirectX 9, try these steps:

• Run in Compatibility Mode
  Right-click your 3ds Max 9 shortcut, go to Properties > Compatibility, and:
  • Check "Run this program in compatibility mode for" and select Windows XP (Service Pack 3) or Windows Vista.
  • Check "Run this program as an administrator".
  • Check "Disable display scaling on high DPI settings"—this fixes many UI rendering glitches on modern high-resolution screens.
• Adjust Graphics Driver Settings
  • Roll back your GPU driver to an older version: Newer drivers often drop support for legacy software like 3ds Max 9. Go to Device Manager > Display adapters, right-click your graphics card, select Properties > Driver > Roll Back Driver.
  • Or, download a legacy driver version from your GPU manufacturer’s website—look for options marked compatible with older 3D applications.
• Disable Hardware Acceleration on Startup
  Hold down the Shift key while launching 3ds Max 9—this opens a startup configuration window. Select Software Rendering or disable any hardware acceleration-related options. This bypasses GPU-specific conflicts that might be freezing the welcome screen.
• Repair Your 3ds Max 9 Installation
  Insert your installation media (or run the setup file from your downloaded installer), select the Repair option. This replaces any corrupted or missing program files that could be causing the issue.
• Close Background Applications
  Open Task Manager and shut down unnecessary programs (antivirus tools, other 3D design apps, cloud sync services) that might be using system resources or conflicting with 3ds Max 9. Some security tools block legacy software from accessing critical system components.
• Roll Back Recent Windows Updates
  Recent Windows 10 updates can introduce compatibility problems with old apps. Go to Settings > Update & Security > Windows Update > View update history > Uninstall updates, remove the latest cumulative updates, restart your PC, and test 3ds Max 9 again.
