Does this happen in or just one specific room?

Temporarily disable your antivirus during the installation process to prevent file quarantine. To narrow down the best solution, let me know:

| Issue | Solution | |--------|----------| | “Failed to install room” | Uninstall IMVU completely → delete %localappdata%\IMVU → reinstall from IMVU.com | | Stuck at “Loading 0%” | Disable VPN / proxy. Switch DNS to Google (8.8.8.8 / 8.8.4.4) | | Room installs but stays black | Update graphics drivers. In IMVU settings → turn “Advanced Lighting” → restart | | Web version (IMVU Next) fails | Switch to IMVU Classic desktop client (more stable for rooms) |
