Hi all, Question 1: What I'm trying to do is: that my app needs Autodesk Map 3D 2005 and I HAVE TO install my app with Autodesk Map. I'm using "Wise for Windows Installer", and when I lounch acadmap.msi, whith cmdline like this: ACAD_SILENT_LICENSE=YES ADDLOCAL=ALL INSTALLDIR=[ACADDIR] ACADSERIALPREFIX=[SERIALPREFIX] ACADSERIALNUMBER=[SERIALNUMBER] ACADDEALERNAME = "MyCompany" ACADDEALERPHONE = "8-699-52777" Installation begans, but when it starts to copy new files I'v got an error "AecXmlBase45.dll is not valid short file name" and installation exits. :( Question 2: Autodesk Map 3D 2005 consits off 2 CD's. How to tell to installer that it have to ask another CD? (Which property is responsable for that?) P.S. If my post is not for this newsgroup please tell where I must to post it. Thanks
