The installer is working fine for me now on Win 10 64bit, w/ Office 2013. No errors so far after installation.
I tried out the new Slice function (thanks btw!), and while it appears to be working, I'm getting an error message before the results display. Unlike the example you provided, I'm also wrapping the formula with the Dump function.
=Dump(Slice(XPathOnUrl(B2,"//div[contains(@class, 'brs_col')]/p[contains(@class, '_e4b')]"),1,0))
So I was just doing a test to scrape the "Searches related to..." at the bottom of the page.
But then the results appear correct.
Was the new Slice function meant to be used on it's own in place of the Dump function when trying to return all the values of an array? When I tried using Slice and Xpathonurl alone as in your example, it only returned one result.
