We have heard of three reports from users who received the above error when trying to install BigOven or InspiredCooking Deluxe from a CD-ROM. The issue has to do with a bug in InstallShield, where it confuses the hard drive with the CD-ROM on some machines. There's an easy workaround.
First, double-check that there is adequate space on the hard drive.
If there is enough space, simply use Windows File Explorer to copy the the entire contents of the CD-ROM to a temporary location on your PC (e.g., a directory called c:\temp). Then, run the installation program from there. After the program installs, simply delete the temporary folder.
If there is not enough space to install BigOven, then of course you need to free up some space to install it. :-)
