Please add "winPreVista" to IUSE_VMWARE_GUEST in the app-emulation/vmware-tools ebuilds. I am not certain when this guest was introduced.
now it should be fixed in the overlay
REFERENCE: Bug 616958 : 12.5.7 version bump including app-emulation/vmware-tools-10.1.6.5214329 . vmware-tools-10.1.6.5214329.ebuild contains: IUSE_VMWARE_GUEST="... windows winPre2k winPreVista" Thus, to me, this bug seems to be FIXED / OBSOLETE; BUT: "winPre2k winPreVista" refer to versions which are _not_ supported any more and - if really used - would induce severe security risks. On the other hand, they are _still_ supported as possible installations by VMware Inc. / VNware-Workstation 12.5.7.5813279 !? @ Thomas / security@gentoo.org : Your judgement?
