How to Install 64-Bit Guest OS on 32-Bit VMware Workstation and 32-Bit Windows?

This situation is going to be very rare but will be useful if you are under this circumstances. This guide shows you how to install the 64-bit version of Windows or Linux virtual machines in 32-bit of VMware workstation which runs on the 32-bit version of Windows OS (Host computer- your physical computer).  Why did I say it as a rare case? If you have the latest physical computer and Windows 10, it is mostly going to be the 64-bit OS and hardware. Also, the latest VMware workstation does not support this option to modify the settings.

If you are still using the old computer and Windows 7 32-Bit as the host computer, then you must read this guide. Most, probably you will have the VMware workstation 32-bit only. This article explains how to check the processor compatibility and Install 64-Bit Guest OS on 32-Bit VMware Workstation

Do you like to run Windows 2008 R2 or Windows 7 64 Bit on your 32-bit host operating system? Then use the following tool and maker sure that your computer processor supports 64-Bit architecture and Virtualization Technology (VT). It is the physical processor feature, so if it has the particular architecture, then you are lucky to have the 64-Bit guest OS if not, nothing can be done.

To disable or enable VT on BIOS read this post.

Download Intel processor utility by using this free tool from Intel Site. After running the tool, it should show the support of Virtualization Technology (VT) and Intel 64 Architecture. 

64bit Guest OS

Above screen indicates this host can have 64 bit OS because VT and 64 Bit enabled.

How to install 64 Bit Guest OS in 32 Bit Host OS Using VMware?

Once the processor test result is ‘Yes’, select the 64 Bit Guest OS from the list in VMware.

64bit Guest OS

If 64-Bit not supported on your host then the following message will appear. You can ignore it and complete the VM creation.

64bit Guest OS

Once all set to start the 64 Bit guest OS, go to ‘Customize Hardware’ or ‘Edit virtual machine settings’, then select ‘Processors’. If your processor is dual core, then you can select two in the number of processors. In the Preferred mode, better to leave it as ‘Automatic’, so VMware will adjust the processor mode as per guest operating system’s requirement.

Now, start the 64-bit guest OS installation in 32 Bit host OS VMware, it will start and work fine.

  1. Dear MR
    i have read your posted, but i don’t understand. would you explain more, what must do it and download, thanx verymuch


  2. Dear,

    It is not “Intel 64 Architecture” which decides whether the system should runs 64 bit guest but the same is decided by “Virtualization Technology (VT)”
    There are many processors in market which has “Intel 64 Architecture” but not VT enabled.(eg:Core 2 Duo T6400,..)


  3. Thanks!!!
    I followed your instructions and it worked like a charm. One question though. When I go to computer properties it says that my virtual machine is running at 32bit. Is this because the host is 32bit or is something wrong?
