Cannot install any addon missing b_l info

I had some problem with bsurface, taken by frustration I removed my preference, update my addon, but it don’t work correctly anymore. So turn back to factory setting and try to install my favourite addon from scratch, and then started the nightmare, cannot install any addon, all give me error fake_module missing bL_info, here a screenshot:

nothing work. So unistall blender, download again, delete all folders, in appdata and program folder, nothing to do, don’t work (also appear a new error…)

all this addon worked correctly with previous installation (until yesterday…).

Any idea about? Cannot work with this issue.

I’m on Windows 10 64 bit
phenom x6 1090t, gtx 580 3gb, 16 gb ram

Thanks in advance
