I don't know what exactly is meant by "set up a 32bit environment inside the 64bit system" but as far as I know you only need to install the scanning related software as 32-bit packages, i.e. a scanning user frontend like XSane as 32-bit package together with 32-bit packages for the SANE base software (i.e. packages like sane-backends and so on). Then it should work to download and install the 32-bit packages from Epson Avasys. Reasoning: 1. A scanning frontend links with the SANE library libsane.so which is in fact the dll pseudo-driver. 2. The dll pseudo-driver dlopen()s the other drivers which is here the epkowa driver. 3. In this particular case the epkowa driver needs a proprietary 32-bit-only library to operate the scanner. Therefore on a 64-bit system: If one runs a 64-bit scanning frontend (e.g. the 64-bit version of scanimage or xsane) then it links with the 64-bit version of libsane.so.1 which again wants to link with the 64-bit version of the epkowa driver which would fail if only the 32-bit Iscan package from Epson Avasys is installed but would wotk if the 64-bit Iscan package from Epson Avasys is installed. In the latter case the 64-bit epkowa driver wants to link with a 64-bit version of a proprietary driver library from Epson Avasys but this would finally fails because there is only a 32-bit version of these library. In contrast on a 32-bit system: If one runs a 32-bit scanning frontend (e.g. the 32-bit versions of scanimage or xsane) then it links with the 32-bit version of libsane.so.1 which again links with the 32-bit version of the epkowa driver which then can link with the 32-bit version of the proprietary library so that your scanner works. Summary: It should work if one installs on a 64-bit system the full scanning software only as 32-bit software but I never tested this on my own because I do not test scanners which need proprietary software stuff. By the way: An installed 32-bit version of XSane might require a 32-bit version of Gimp (which would require lots of other 32-bit libraries) when the XSane Gimp-plugin should be used to acquire an image from the scanner directly from within Gimp.
