I dont think they can guarantee that at this moment with Tableau Prep.
I have most of versions installed on my Windows just in case I see if a version is crashing a lot I go back to an earlier one. Today I used 2019.1 and it was ok on Windows 10.
I would give it a try and fingers crossed it will work for you. Performance seems a bit improved on W10.
Thank you for sharing your findings.
Actually I had this issue in Prep 2018.3.3 on Windows 2007, were Tableau Prep stopped running because an underlying process stopped unexpectedly. If this problem continues, try reinstalling the product."
Did followed the steps suggested by support. but didn't help at all.
So thought of posting in community before upgrading if anyone has given a try.
Is there a bug with Prep 2018.3.3 on Windows 7? Ciara Brennan
Hi Chaitanya, I haven't heard of a bug with 2018.3.3 and Win7. Did you get back on to Tech Support about it?
