How to install patch on Uniface 9.3.1

HI, the patches are self unzipping zip archives. 

However, since they (mostly) overwrite the urouter/tomcat code, you can get an error (usually about the file ucall), You need to go to your windows services and stop both these services.  (They will be named as you named them on install, but they're the Urouter service (Uniface Urouter?) and the Tomcat services (I seem to recall that 9.3 called that "Apache Tomcat")). 

Then execute the patch (from anywhere) and browse to your uniface install folder. It'll unzip over all the files in there, then start those two services again.
