The System Requirements page indicates that a 64-bit host OS is required, which implies a 64-bit CPU. At the bottom of the page, they say that you can run a 32-bit OS inside VM Player which is probably not what you want. They further clarify that VM Player Plus 6 is the last version to support a 32-bit OS (and CPU) and that you can purchase Player 7 and downgrade the key in order to use Player 6 with a current license and support.
If you want it for personal use, then VM Player 6.0.7 free (non-Pro, non-trial) is—at the time of this writing—the last version that you can get which will run on a 32-bit CPU.
If you are wondering what features you will be missing out on, you can check the Release Notes of later versions. For the most part, it is just bug- and security-fixes, occasionally adding support for new OSes (e.g., Windows 10), improving performance, changing/adding/improving the virtual hardware devices, and sometimes changing system limits.
In case you concerned about using an older version, notice that VM Player 6.0.7 was released on July 7th, 2015, a full 7 months after version 7.0.0 was released. This shows that they have not completely dropped support for version (32-bit) Player 6 and are, for the time being, providing security-fixes and even bug-fixes. You can also request support for any problems you encounter by posting in the VMWare Player forums.
The Windows version is not enough to answer compatibility questions. The actual CPU is much more important. – Daniel B – 2015-02-04T13:36:32.657
I've added a screenshot which is pretty self-explanatory + cpu info – knarf – 2015-02-04T13:59:30.350
VMware Player 7
is 64-bit only. This means your limited to using the previous version which would beVM Player 6
which you have in your folder display in the screenshot. – Ramhound – 2015-02-04T14:06:57.800I found it on oldapps.com and was reluctant to run it since I have no way to know if the file is genuine. – knarf – 2015-02-04T14:08:55.210
