Golddiggie, thanks for the excellent suggestion - that worked perfectly!
Interestingly, the extract process created a new "VMware-workstation-full-7.0.1-227600.exe" in the extract folder, which is just a few kB smaller than the downloadable version. And this new exe worked fine (as did clicking the msi file directly).
I have no idea what caused the original problem - something in the wrapper, but I can't imagine what.
Anyway, thanks a million - installing now, so I hope it all goes well.
Cheers,
Michael...
