Request for D5 Lite for SketchUp v1.5.0 Installer

Dear D5 Support Team,

I am currently experiencing an issue with D5 Lite for SketchUp v1.6.0 .

My environment is:

  • SketchUp 2026
  • D5 Lite for SketchUp v1.6.0
  • Windows 11
  • NVIDIA RTX 4090
  • D5 Render itself works normally

The problem is that D5 Lite does not launch from SketchUp.

The log shows errors such as:

[SessionGuard] strong ready barrier failed

app_session status=failed

failed to open editor through RPC: 0

I tested the same installation using a newly created Windows user account with an English-only username, and D5 Lite appears to launch normally under that account .

However, my main Windows user profile uses a Korean username, so the user folder path contains Korean characters:

C:\Users\황진웅

Therefore, I suspect that D5 Lite v1.6.0 may have an issue handling non-ASCII / Korean characters in the Windows user profile path.

I would prefer not to create or migrate to a new Windows user account just to use D5 Lite.

Could you please provide me with an offline installer or download link for an earlier version of D5 Lite for SketchUp, preferably v1.5.0 ?

I would like to test whether v1.5.0 works correctly with my existing Korean Windows user profile.

If v1.5.0 is unavailable, any previous stable version compatible with SketchUp 2026 would also be appreciated.

Thank you for your assistance.

Best regards
