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?
