It seems there is something happening on the versioning.
Latest version downloaded from Invantive Query Tool
Install creates an .exe with version 23.0.94:
On Query Tool, from Help, it says “Unofficial”
Version 23.0.128 dowloaded from Release notes
Invantive Query Tool
creates a .msi file of 270 MB but install does not work (install window appears for a few seconds then disapear and nothing else).
A sharp eye!
The display of “Unofficial” was a bug introduced in 23.0 and fixed on the latest releases.
However, these are not yet downloadable as release 24.0 is upcoming. For urgent issues, please use the latest 23.1-BETA, which will largely resembly the release 24.0.
