Hi. Have the problem.
After Update windows 10 (from 2015 to 2019) I can't edit SQL code in components, but stil can build projects. Error: "The Query Builedr is not installed, you can download it for free at www.allrountautomations.com"

Delphi run as Administrator

The Query Builder can be downloaded here:

https://www.allroundautomations.com/files/qb.exe

Thanks for the help, it works. But still can't open SQL Editor and Variables Editor... in popup menu. Cant see errors. After trying to launch the SQL Editor or Variables Editor, the Delphi environment becomes unavailable

Problem solved. The problem was this: I used to have two monitors, brought a laptop home, and there was one monitor. Plugged in a second monitor and it worked. Although this problem is not related in any way, but it can be useful to someone
