On the search for a hidden bug related with an other program I decided to uninstall my 2 versions of the Windows XP Mode on W7 pro x64; i.e the "independent" (non-VMware) and the Workstation 12 Player also with the XP Mode. Both VMs did before work normal. Because these VMs may possibly have had some relation with a bug in an other program I decided to remove them again for verifying it. The uninstall was started "as usual": Start -> Control Panels -> Programs. I do not remember but at some state I had also to use this Microsoft Fix-it-tool. The tool confirmed that the programs have been successfully removed and they are no longer listed under "Porgrams". The VMs have however not been completely removed. The folders VMware and its sub-folder VMware Player are still there with their contents. Starting the player shows the XP Mode; clicking on it produces however an internal error. The "independent" (non-VMware) XP Mode produces also an error asking for a new configuration file. Assuming that it would possibly be best to first completely remove the 2 VMs and install them afterwards completely new I tried to manually delete all of them which are in a folder under "Virtual Machines" but I was not granted permission, even being "owner" and "administrator". Any suggestions on how to obtain again "clean" Windows XP on the VMware Player? Thanks in advance for helpful suggestions.
