3112074 - Tomcat and SIA are not starting or responding after an upgrade [cannot load hsdis-amd64.dll]

After an upgrade from BI 4.2 SP06 to BI 4.3 SP01 patch 600

• SIA is not starting.
• Tomcat is not responding. Although Tomcat shows as running but is not responding after install finishes.
• Tomcat work folder is not getting generated.
• The sizes of either of sapjvm bin folder, tomcat bin folder and lib folder are different when compared to a working server.
• Tomcat is not responding (part of original issue) and this is being looked into.
• This error is seen in the BI 4.x install logs (setupengine.log) and tomcat stderr logs as well
