If you problem is not resolved, can you share your log file please ( https://wrobot.eu/forums/topic/1779-how-to-post-your-log-file-with-your-topic/ ).
You get black screen (mainly when you use remote desktop software or when you try to record or take screenshot)
Since WRobot 2.0 you can get a completely black WRobot window when viewing with remote software like TeamViewer, to resolve it:
Close WRobot
Open and edit with notepad file "WRobot\Settings \RobotManagerGlobalSetting.xml"
Replace
<CanProtectAgainstScreenshots>true</CanProtectAgainstScreenshots>
by
<CanProtectAgainstScreenshots>false</CanProtectAgainstScreenshots>
(if you don't found first line, add second line before "</robotManagerGlobalSetting>")
Save file and you can relaunch WRobot.
Hello,
Check if your framework version is updated, you can also try to close WRobot and edit with notepad file "WRobot\Settings\RobotManagerGlobalSetting.xml" and replace "<CanProtectAgainstScreenshots>true</CanProtectAgainstScreenshots>" by "<CanProtectAgainstScreenshots>false</CanProtectAgainstScreenshots>"
It is remote deskop?
