See the IBM Informix machine notes for a list of supported Windows operating
systems on which you can install the products.
Important:
The following requirements might be lower for your system,
depending on the operating system and environment.
A typical installation of the IBM Informix software bundle requires approximately
750 MB of disk space. Some installation choices require additional disk space. The
installation application informs you of the total disk space required by your setup
before you copy the binary files to your host computer.
An installation requires approximately 1 GB RAM.
Ensure that you have 1 GB free space available in your temporary directory before
installation. This is to allow the extraction of the installation media and for
running the installation program. This location can be altered by setting the
IATEMPDIR environment variable to a location that contains sufficient storage
prior to invoking the installation program.
32-bit installation media on 64-bit Windows computers
If you want to use the 32-bit installation media on a 64-bit Windows computer, the
Windows 32 on Windows 64 bit compatibility folder (usually %windir%\SysWOW64)
must occur in the path environment variable in front of the native 64 bit folder
(usually %windir%\system32) before installation is started. Failure to meet this
prerequisite can result in an aborted installation because of a missing prerequisite.
The suggested method for starting the installer is to open a command prompt, add
the compatibility folder to path (set path=%windir%\syswow64;%path%), and then
run the installation application from this command prompt.
1.
Open a command prompt.
2.
Add the compatibility folder to path. For example, if the Windows on Windows
compatibility folder is in %windir%\SysWOW64, set path=%windir%\sysWOW64;
%path%
