Parallels tools won't install

I installed the latest version of Parallels today (22 September 2016). Parallels tools refuses to reinstall. I have tried a number of times by selecting "reinstall parallels tools" in the Actions drop down menu, but each time I get an error message saying that Parallels tools won't install, and suggesting a reboot. I have tried the options in the Parallels knowledge base, article 8969. The first option (uninstall and reinstall parallels tools) doesn't work because there is no parallels tools installed and the second more complicated option seems to be set up for an older version of windows than windows 10, and anyway the options aren't available eg I can't uncheck items in the startup tab of system config - possibly because you need Tools installed to do this, anyway I can't do it.

 

And here are the screenshots for the two error messages.
Shot 1 is the error message when selecting reinstall from the action menu:

Shot two is the error message from scenario 3 from article 112609:

 

Resolved

 

It's an interesting case, please share your solution if it's not a big deal.

 

Well, it fixed itself somehow. There was a big Windows update that happened yesterday. I don't know if there is any connection, but last night I tried again, without any expectation of success, and Parallels tools just installed without any problem.

 

Well, seems like some Windows updates could be quite useful stuff).
