Sound Forge Pro 11 is a 32 bit application, there is no 64 bit version. However it runs without issue on a 64 bit PC.
OTOH, Sound Forge Pro 12 is 64 bits, and supports 64 bit VST-3 FX plug-ins. A 32 bit version of it can be installed if you so desire, even on the same PC . For instance, some Direct X plug-ins like the iZotope Mastering Suites which came with Pro 9 and 10, do not function on 64 bit Pro 12.
