WSA shouldn't be interfering with any of your installations "if" they are Good files. When a new file is introduced into the system, WSA will takes its signature and try to make a determination in the cloud, checking if we have seen that software before. Malicious is obviously stopped, Good is permitted, and if it is Undetermined, we will run the installation in a sandbox, looking for malicious activity. If all is well, the program is allowed to install.
If you are experiencing any installation issues at all, I would encourage you to open a support ticket, using Help and Support inside of WSA, the log files are automatically loaded with your ticket and support should be able to assist in troubleshooting should there be a valid issue.
