If you get this message it is most probably because you have an underpowered PC which is struggling to run the virtual PC environment. To fix this you will need to uninstall the version included with your manual and install an older version of the VMware player that is more suitable for your PC.
Step 1 – Go to your control panel and under the add or remove programs section you need to select VMware player and uninstall it. Then restart your PC.
Step 2 – Download and install an alternative VMware player from here, all versions are free for personal use.
Step 3 – Once the new player has been installed you will need to edit the configuration file of the manual you have downloaded in order for it to be compatible with the older version of the VMware player software, don’t worry it’s very easy.
Locate the “Virtual Machine” folder where all of your manual files are located. You now need to find the “VMware Virtual Machine Configuration” file (this has a an icon next to it that looks like 3 blue windows overlayed over each other). Right click it and choose to open it with notepad (don’t set this as the default program though).
Locate the following text:
virtualHW.version = “9”
Now change it to:
virtualHW.version = “7”
Save it and close it making sure you kept the file in the same format (.vmdk).
Step 4 – You can now double click the configuration file and it will open your new version of the VMware player which should now run correctly.
