Firstly, in order to fix the issue, perform a full system scan using your security program or a utility from Software Informer database. After that, remove the program from your PC and run CCleaner to make sure that there are no leftover registry keys in your system. Reboot your computer and install the software again. Once the process is complete, right-click on the launcher and select Run as Administrator. If it doesn't work, reboot the computer press the F8 key and try running the application in Safe Mode. If it works, a program from your PC is conflicting with Reuters News Suite Server. To determine the program that cause the issue, you will need to perform a clean boot. If this doesn't help, right-click the Reuters News Suite Server launcher, select Properties and open the Compatibility tab. Check the Disable desktop composition box, click Apply, OK and try to run the software. If none of these help, you will need to contact the developers.
