How to properly update xlwings
Question: After xlwings is updated from `0.6` to `0.7.0`, I have the following problem.

**Although xlwings works** , when I click **Import Python UDFs** , I get an
error that tells:

> Run-time error '1004' Cannot run the macro...

The macro may not be available in this workbook or all macros may be disabled.

_Xlwings_ web site only tells about installation of the package. I could not
see steps for upgrading the package.

What is the proper way of upgrading _xlwings_? What should be the steps for
the upgrade?


Answer: The python package itself is updated like every other package (`pip install
--upgrade xlwings` or `conda upgrade xlwings`).

Updating the Excel add-in is explained
[here](http://docs.xlwings.org/en/stable/command_line.html#add-in-currently-
windows-only), the easiest way is to run `xlwings addin update`.

However, this expects that you have also installed the add-in previously with
`xlwings addin install`. If not, you could also update it manually by
replacing your current version (wherever that is saved) with the latest
version that is in the xlwings package (run `>>> import xlwings`, `>>>
xlwings.__path__` to see where the xlwings package has been installed).

By the way, I assume you're facing [this
issue](https://github.com/ZoomerAnalytics/xlwings/issues/331) that had been
fixed with v0.6.4
