Hola! Tengo licencia permanente de PIX4Dmapper v 4.7.5 y windows11. Y desde hace unos meses el programa no funciona. Anteriormente sí que ha funcionado esa versión con W11. Solo parece la ventana de inicio del programa (adjunto imagen) y después desaparece. He leído mucho sobre este problema ([Windows 11 issue with PIX4Dmapper, PIX4Dfields, PIX4Dsurvey, and PIX4Dmatic [e9041]](https://community.pix4d.com/t/windows-11-issue-with-pix4dmapper-pix4dfields-pix4dsurvey-and-pix4dmatic-e9041/20960)) y ya desinstalé el programa OneDrive y actualicé los controladores NVIDIA. No me es posible regresar a windows 10. Además desinstalé QGIS, porque leí que alguien había desinstalado POSTGRESQL y lo había resuelto. Alguna idea??? Muchas gracias de antemano. ![captura_pix4dmapper](https://global.discourse-cdn.com/pix4d/original/2X/8/879315b21d878da0054442d1a9e00350ec9612a1.jpeg) ---

Hola! Gracias por su respuesta. Pero ya dije que había actualizado la tarjeta gráfica NDIVIA. Finalmente el problema venía de la variable de entorno PROJ\_LIB. La eliminé y el programa empezó a funcionar. Saludos ---
