The first task you need to complete is to make sure that your computer meets the minimum system requirements. If your system does not meet these requirements, problems can occur, both within Infrastructure Map Server and at the operating system level.
Whether your operating system is Windows (32- or 64-bit), or Linux, the version is automatically detected during installation. The appropriate version of Infrastructure Map Server is installed. A 64-bit version of Infrastructure Map Server cannot be installed on a system running Windows 32-bit and vice-versa.
