    Since all the new dell laptops are running 64 bit now - how well will the 32
    bit acad 2012 run on 64 bit..... I still have Win XP Pro 32 bit and would
    like to not have to buy 2 versions of Acad..... what type of gains does the
    64 bit have as opposed to 32 bit

    I have W7P-64bit, and haven't had a lot of problems running most 32-bit
    programs. The one exception was trying to load AutoCAD 2000 - the 32-bit
    installation program would not run... Which is why I upgraded to AutoCAD
    LT 2009, and even then I had some some issues with trying to install
    some of the service packs for it - W7P-64 would not run them. Recently
    upgraded to AutoCAD LT 2012 and haven't had any problems. Not really
    sure if it installed as a 32-bit or 64-bit app, but I'm thinking it was
    64-bit.

    IMO, unless you're working on some large & complicated stuff, the
    difference between 32 & 64 shouldn't be noticeable..

  3. Problem one was AutoCAD 2000 trying to be installed on an OS that it
    does not support; Win 7 in this case.
    Same issue with AutoCAD LT 2009 on a Win 7 OS: It is not supported.
    LT 2012 is supported on Win 7 OS which is why it would load.

    Generally 32 bit programs will run on 64 bit machines but not the
    reverse. Issues can arise from the OS but Win 7 Pro, Ultimate, and
    Enterprise offer an XP emulation modes that allows XP and Vista based
    programs to be loaded. This may be what was need to be used to install
    the 2000 software. The start up will tell you whether or not the OS is
    32 or 64 bit. Also if you right click the My Computer icon on the
    Desktop and choose Properties this will list the OS bit rate. Same can
    be done from the Help; About dropdown in AutoCAD

    64 bit is the future and will run faster. Look for a minimum 6 gigs of
    RAM and certified graphics cards. You may also need to look at turning
    off Win 7's Aero theme too. Google running AutoCAD 2012 on Win 7 for
    other speed enhancers.

    The setup.exe for ACAD 2000i is 16 bit. I managed to install 2k on 64 bit
    Vista using Epsilon Install Kit. Be interested to know if Win 7 solves the
    problem, otherwise I guess I'll shift to Draftsight.

    I had very little trouble installing Acad 2000i on Win7 pro 64bit.
    1) Use a NON administrator account to install and run ACAD 2000i
    2) Give users full access to C:\Program Files (x86)\AutoCad 2000i
    3) Right click on Setup.exe and select "Run as Administrator"
    4) Ok the error message hiding behind the progress bar.
    5) If needed, run the service pack u090_u181p.exe as administrator.

    If you have express tools, install them manually
    Copy acettest.fas to C:\Program Files (x86)\Autocad 2000i
    Copy the \migrate express tools\express folder to C:\Program Files
    (x86)\AutoCad 2000i

    Start AutoCAD from the desktop icon. You may get the "Failed to update the
    system registry. Please try using REGEDIT". error. It's an irritant but
    doesn't seem to cause a problem. There are some usability issues, mostly
    with the clip board. One user reported that it doesn't always respect file
    locking.

    Is that the catch - ok in Pro, not in Home Premium?

    So I get Pro if/when I need to upgrade, and I'll keep your instructions -
    thanks.

    I can't say if Pro allowed it to install and run; it's the only version I
    use. I do know that running as admin made W7 unworkable in my environment.

    Another option: Longbow. Allows a user to run older 32-bit software on newer 64-bit machines.
