I have tried to install QB desktop 24 literally about 100 times and it fails every time with a 1603 error code. I called QB support, screen shared and followed all steps until they couldn't help any more and gave me guide to repairing my .NET and MSXML. Nothing has worked. Has anybody ran into this, or might have some tips to try? My only thought was I downloaded microsoft visual studio and made a program built on .NET. I removed Visual before I even called QB support. It is worth mentioning I am in a dealership and my computer is the only one is having trouble installing QB desktop 24
