Solution
This can usually be solved by the following steps:
1. Go into NI Package Manager and make sure that the
Show full version numbers and infrastructure packages option is checked from inside the menu accessed by selecting the cog in the upper right-hand corner of NI Package Manager.
2. Go to the
Installed tab uncheck the box
Products only. 3. Enter "rabbit" into the search bar. Uninstall anything that shows up in that list.
4. Go to the Windows Add or Remove Programs menu and search for the RabbitMQ server entry. Make sure to uninstall this as well.
5. Restart your computer and try installing SystemLink, FlexLogger, or the LabVIEW NXG Web Module again.
If this didn't solve the problem, you can try deactivating your anti-virus. This is because security software can sometimes block the installation of RabbitMQ or other dependencies of SystemLink, FlexLogger, or the LabVIEW NXG Web Module.
