Installing DNVM in Windows 7 fails if username contains special characters

[nordbergmikael]

On my home PC I use the user account "Yours & Mine". DNVM install fails with:

@flykoh What's the version of dnvm?

[glennc]

Closing this one, without more information about what version of dnvm and what the username is it is hard to diagnose. We have had problems with spaces in usernames, and we did some work to fix that. So it is possible if you have an older DNVM that you haven't got that fix. Otherwise if it is still happening on the latest DNVM then you should post back and tell us what the username that is breaking is, see if it is a special character or something that causes the Powershell script to break.

We will re-open if we get more info :)

I am experiencing the same issue. My username contains an apostrophe.
