I don't know if anyone else here is using QB Pro2006 but I thought I'd ask. QB did an auto update this morning, but the update won't install. I'm getting a 1603 error from QB's installer.
The info at Intuit's site says that's a Windows Installer problem and to delete it and re-install WI. Which I did and I went to MS's site to get the latest version of WI. WI installed fine.
Try to update QB again and get the same error. Anyone else having this problem with a recent QB update? I'm currently on R10P.
