Is it possible to downgrade an installation of Windows XP x64 to x32 without losing the software profiles?

    Accepted Solution

    As far as I am aware - you will have to do a reinstall.

    It is similar to upgrading from 32-bit to x64 - you require a reinstall in that case as well.

    There may be workarounds - but I would suggest for system stability that you follow this course of action.

    Correct, it requires a full reinstall from scratch.....

    How about the software profiles ?

    By "software profiles" I take it that you mean "Program Files"

    These will have to be fully installed to make certain that the programs run - as far as I am aware - a 64-bit registry is incompatible with a 32-bit one - so your programs wouldn't run in any case - even if you ghosted them over.

    I recommend that you backup your important data - and reinstall windows and your programs for a reliable solution.
