Windows 10. I've not used my 3 installations of QGIS for 6 weeks maybe. I updated them via OSGeo4w but I get the error "The code execution cannot proceed because OpenCL.dll was not found. Reinstalling the program may fix the problem".
OSGeo4w gives me the error
Package: qgis-common qgis-common.bat exit code -1073741515. Package: qgis-ltr-common qgis-ltr-common.bat exit code -1073741515
Reinstalling the programmes produces the same errors. Can anyone help please?
