Portable Catia V5 R21 generally retains the full functional capabilities of the standard platform, assuming the package was built using an all-inclusive hybrid license profile (like HD2 or AL2). Users have access to the core workbenches that made R21 famous:
| Problem | Likely cause | Workaround | |---------|--------------|-------------| | “CATIA application failed to start” | Missing VC++ 2008/2010 runtimes | Install runtimes locally or place DLLs in app folder. | | License error -1 / -5 | Emulator blocked by antivirus | Disable AV or add folder exception. | | White screen / no 3D view | OpenGL incompatibility | Run in software OpenGL mode: set environment variable CAT_OPENGL=0 . | | Crash on file save | USB drive removed or full | Save to local drive first, then copy to USB. | | Slow startup | Large settings folder | Delete CATSettings subfolder (reset settings). |
