    Virtual PC problem

    I just now installed Virtual PC 2007 on my husband's laptop which has Windows XP Tablet OS installed. I created the virtual machine, installed Windows XP and everything works fine. I then installed OrCAD which is the program he wants to use, but the installation fails. He has this installed on a desktop running XP so it should work.

    Are there updates to Virtual PC that might solve this?
    Should I try installing Virtual PC 2004 (which I have on a CD from a previous MSDN subscription)
    Is there a list of programs which it works for?

    Re: Virtual PC problem

    Hi Deb

    I have a few problems with VPC 2007 and just went back VPC 2004 out of pure expediency as I had deadlines and got it running OK ( I virtualise servers and have ony one XP to play with)

    I have also found in the past that the Tabley XP operating system is a real pain as it does not have the same drivers etc from a "normal" XP desktop installation, and I guess this is why you are doing what you are. The Virtual XP will be looking at the Tablet OS system and probably cannot emulate the drivers.

    Try 2004 and see...it is what I would /have done just to see if it will work....but check for any service packs etc before you do <img src=/S/grin.gif border=0 alt=grin width=15 height=15>

    Just an after thought, does the Tablet have enough RAM?

    Re: Virtual PC problem

    Thanks for the sanity check. I to suspect it's the XP Tablet OS although Virtual PC does list it as a supported OS during install. I'll uninstall Virtual PC 2007 and install the 2004 version and see what happens. The error message I get during install of OrCAD is something about not being able to create the program group. I don't remember the exact wording right now but I assume it's referring to the menu item and directory structure under Start/Programs. It does however, create it and I see OrCAD in the Programs listing but it's empty.

    Maybe what I'll do is look at the structure on the working Win XP computer where OrCAD is working and duplicate its directory structure (and maybe registry). I don't know if replicating those on the XP Tablet laptop would confuse the installation program though.

    Re: Virtual PC problem

    Does this system meet or exceed the system requirements?

    Re: Virtual PC problem

    Yes, this laptop exceeds those specs. It's the Gateway Tablet PC, http://www.gateway.com/programs/convertibl...ex.php?rdr=v116 and is about 6 months old. It has Windows XP Tablet as the OS which isn't listed in your spec but it's listed in the drop down menu in Virtual PC during the install.

    I don't have time to try Virtual PC 2004 for a few days, but will update this post if anything changes.

    Re: Virtual PC problem

    You might check with OrCAD and see if it will run with Tablet PC, as it id different than the XP Pro or Home. I have seen several programs that will NOT run on a Tablet PC.

    Just because Virtual PC will install, it does NOT mean that ANY program will run on it. You may need to install a version of XP Pro or XP Home under Virtual PC to install OrCAD.

    Re: Virtual PC problem

    Good idea to confirm if OrCAD will run on XP Tablet. The OS I installed on Virtual PC 2007 was XP Pro (I have the CD from a previous MSDN subscription) and I still got the error when installing OrCAD so there still must be some ghosts of XP Tablet that XP Pro is seeing when run from Virtual PC. This would imply to me that the OS running under Virtual PC isn't completely independent of the computer's booted OS. But I am clueless about the internals. I did find this link http://support.microsoft.com/kb/327160 saying that XP Tablet is a superset of XP which in theory, should mean that if it runs on XP, is should run on XP Tablet.

    This version of OrCAD is quite old but works well on XP. I can't afford the $$$ to update to a new version of OrCAD but I will check if they support XP Tablet (which didn't exist when this version of OrCAD came out).

    I'd be good to see a list of programs that do not work (or that do work, which ever list is shorter) with Virtual PC. I'm sure Microsoft did testing on common consumer-type apps but OrCAD is an engineering design application (for printed circuit boards) so, although it's a very popular program for that task, I doubt it'd make their list of ones to test.

    Re: Virtual PC problem

    Your link to Gateway does not give any system specs. Also a model number would be helpful.

    Yes, Tablet PC is a subset of XP, so is the Home version, but it will not perform and do all that the Pro version will. If I remember correctly, Tablet PC has less than the Home version.

    Re: Virtual PC problem

    XP Tablet is a subset of XP Pro? The Microsoft link I included in one post said it was a "supserset" of XP Pro SP1, not a subset. The extra drivers handle the pen interface and other stuff.

    For the specs on this particular laptop, it has way more than the list another poster provided so it's more than acceptable in that respect for running Virtual PC. As for the laptop's model, "Convertible" is the name, it's the only one Gateway sells which is a tablet. The only options are different memory and hard drive size.

    Later today I'll uninstall Virtual PC 2007 and install 2004 as a test. I'll post back if anything good happens.

    Any thoughts on what the error message "can not create program group"? It's odd because it did create it (it shows in Start/Programs) but its submenu is empty. I considered re-creating this directory structure based on another XP computer I have that already has OrCAD installed.

    Re: Virtual PC problem

    The version of OrCAD was built for what version of Windows?
    Since it is a OLD version, you may want to try installing it by "Right clicking" the 'setup exe' file and select the 'Properties', then the 'Compatibility' tab. Then enter a check mark at "Run.....mode for" and then select the Windows version this program was designed for. Then OK out and then "Double click the install (setup) file, and have a go at it.

    Re: Virtual PC problem

    Ok here's my update... <img src=/S/fanfare.gif border=0 alt=fanfare width=31 height=23> I got OrCAD to work under Virtual PC 2007 by deleting the previous virtual instance which had WIn XP Pro and installed Win 2000 as the OS instead. Even though this OrCAD works fine on another PC with XP Pro, it wouldn't install properly running XP Pro from the tablet.

    I do however notice that the mouse is very jerky when used w/in the Virtual PC window. Is that normal? I haven't installed any special mouse driver but having the movement be choppy and lag the real motion makes it difficult (and annoying) to use especially when working on fine details such as PCB layout.

    Thank you for all the suggestions.

    Re: Virtual PC problem

    I assume you mean for the jumpy mouse cursor problem.... I can do that but I already assigned 300+ MB (I don't remember exactly #), and I only have OrCAD installed. That's one hungry mouse if it uses this much memory. To change the memory I have to delete the vm and reinstall it. I didn't see where I could change this after it was already set (the Settings menu just lets me view it, not edit it).

    Re: Virtual PC problem

    Yes.

    Windows Virtual PC is an emulation of the operating system you have installed within the application. It may have a series of drivers from the Virtual OS but it still has to use the hardware that the host operating system is on, you are not using a new OS but an emulation. An analogous example is DOS in Windows XP, XP does not have DOS but an emulation.

    The layers of a Virtual machine go like this:

    1) Virtual Application
    2) Virtual Operating System
    3) Virtual PC
    4) Host Operating System
    5) Host Hardware
    6) Host Network

    How #1 & 2 work depends on if there are generic drivers installed. I have a Dell laptop with 2 Gb of RAM, when I use VPC for one of my servers I have 1Gb assigned to my Virtual server, that means half of my RAM is used up (#4) and shared between (#2 and #4 above) You may find that the mouse is stuttering because the host operating system has too much RAM taken from it
