Please note that some ProM packages (like LpSolve) use libraries that differ per system, and that 32-bit and 64-bit Windows are different systems. If you change from 32-bit to 64-bit (or vice versa), please remove all packages and install them again (which will install the correct versions of the packages) using the Package Manager before running ProM itself. Tyring to run ProM with a wrong version of a package will not work, as ProM will not be able to load such a wrong version.
First steps
Please see the First steps section of the ProM 6 installation page.
