Hi Doug, 4D v12.6 (final version) was released October 8th 2013. Windows 10 was initially released July 20th 2015.
It is safe to say that v12 was *never* tested by 4D QA on Windows 10 because Windows 10 didn't even exist at the time of the final release of v12. v12.6 is listed as "Not Compatible" Windows with 8.1 (Windows 10 came out after 8.1)... http://download.4d.com/Documents/Products_Documentation/LastVersions/Line_12/VIntl/PDF_Format/4Dv12.6_Certif_Matrix.pdf v13.6 is listed as "Not Tested" for Windows 10: http://download.4d.com/Documents/Products_Documentation/LastVersions/Line_13/VIntl/PDF_Format/4Dv13.6_Certif-Matrix.pdf v14.5 and v14.6 is listed as "Compatible" with Windows 10: http://download.4d.com/Documents/Products_Documentation/LastVersions/Line_14/VIntl/PDF_Format/4D_v14_6_Certif_US.pdf v15.0 was listed as "Not Tested" on Windows 10: http://download.4d.com/Documents/Products_Documentation/LastVersions/Line_15/VIntl/4D-v15_Matrix-Certif_EN.pdf v15.4 is listed as "Certified" for the Win 10 anniversary update, but only "compatible" with the original Win 10: http://download.4d.com/Documents/Products_Documentation/LastVersions/Line_15/VIntl/20170902_CertifV15_4_INTL.pdf v16.0 is listed as "Certified" for the Win 10 anniversary update, but only "compatible" with the original Win 10: http://download.4d.com/Documents/Products_Documentation/LastVersions/Line_16/VIntl/4D_v16_0_CertificationMatrix_EN.pdf if a certified environment is important to your customer and your customer wants to use Windows 10, then you should be looking at either v15.4 or v16. -Tim ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
