I take it that you got the infamous 'The MSI " failed' message, eh?
If it can't be reinstalled, it is almost a certainty that it will never be reinstalled unless you perform a clean install of your operating system...
...Which I had to do when I encountered this problem. I tried their solution, in 2 different versions of Windows (7 and 8.1), with previous versions of VMware Player (7.1.0 and 7.1.1); and it was a complete farce.
I will repeat what I told them: It is absolutely unacceptable to put out a program that cannot be removed. It is even more of a farce when the solution is to go through a maze with a series of procedures, and even THAT doesn't work!
I have never come across a program that had the potential to present this much of a problem if it is uninstalled. I have never come across a program that presented this much of a problem to reinstall, once it has been removed.
My first guess is that the registry of this program can be easily corrupted by the introduction of another program; perhaps one that is as big, if not bigger, than this. Unacceptable.
I gave VMware Player 7.1.2 a test removal and reinstallation on my 64-bit Windows 7 host. I have had no problems removing and reinstalling the program...YET.
If I must say so, any chance you had of reinstalling VMware Player 7.1 2 may have gone out the window the sooner you installed Windows 10. That's not the only program Windows 10 can chop up in a desktop system. My Kaspersky Internet Security was severed from my system, and Windows Backup reported that my backup drive, completely healthy when repeatedly tested in Windows 7, was about to die.
Windows 10 seems to behave better in a laptop. If I were you, I'd downgrade and wait for Win10 Service Pack 1 for the desktop...
...But that doesn't mean that VMware Player will function normally after an OS downgrade. Like I said, anything that can corrupt this program's ability to be reinstalled (after once being removed) will do so. And they have not fixed the problem in as long as FIVE YEARS!
