An error occurred when sending commands to program 追蹤
our BarTender version is Automation 2016 R7, it is installed on 3 desktops which are checking licences using Seagull Licence Server which runs on one of the desktops as a service. SLS runs on Win7 / 64 bit. No internet connection.
The problem is, that on this "main" computer, every first launch of BarTender throws an error message "an error occurred when sending commands to program". Second launch is without problems. If I close the app and lanuch it again, error occurres. Following launch is OK again.
It seems that if I stop running SLS, the problem dissapears and every launch is smooth.
According to Google, the same error message occurs by some Office products (Word, Excel) and is related to DDE (Dynamic Data Exchange). Unfortunately, solutions are Office related.
Please, any idea, how to fix it?
