Your home directory most probably has weird access rights.  I suggest
to take ownership on the entire tree under C:\Users\jan, via the
Windows Explorer's "Security" tab; then restart Emacs and try again.
This will save you a lot of grief down the road.

Alternatively, change the value of %HOME% to point to a directory
outside the C:\Users\ hierarchy, preferably to another volume, like
D:\jan, if you can.  Putting user files on system disk is known to
cause trouble on latest versions of Windows.
