Hi Tomomi - then that must be it - sounds like a bug - can you please update support (the case you opened) with this information - the difference is that we have added more support for multi-languages since NOV and this may be causing an issue.
I am able to use in Hub. Hub is like QS IDE available as desktop version and Enterprise version. Cloud version is like Qlik as a company provides SAAS based IDE where complete platform is maintained by Qlik. But as I know the basic features in all platforms work in same manner.
This error looks to me specific to integration of Feb release with specific version of Excel, I saw today one more post on export issue in Feb release.
So what I am seeing here - is that export to Excel WORKS if you access QS Desktop using a browser via locahost:4848/hub - BUT DOES NOT WORK if exported from inside the Desktop interface - is that a correct assessment?
