regedit fix also posted in Forums worked to fix convertor error so now I have it installed, waiting time to shutdown "Test" Production server.
yeah, test doesn't always mean it is not production. And since it affects payroll.... will wait.
If this doesn't work V2V then yes move all virtual to other host and reboot this esxi host.
With the remaining virtual machine in question shutdown of course.
see if that doesn't shake it loose.
Password to host found, exported files sent to support.
Thanks everyone for Ideas posted, and when I find the solution I will post it.
We now return to "How the Data Center get Glitches" where we hear Maria say, it was that way when I found it.
