Regarding the OP’s problem, it appears the installer exe requires to use resources held by other processes. For me it was Skype and Logitech wireless mouse software.
To work out what is “blocking” the installer:
- start task manager, you’ll see setup.exe running as a background process but consuming no CPU cycles.
- click on the “Details” tab in task manager
- scroll down to setup.exe, right click on it and select “Analyse wait chain”
- close the program / end the process which setup is waiting on
You may have to repeat steps 3 & 4 if there are multiple contentions. For me once I killed Skype & Logitech processes the installer popped up instantly. Also I ran setup.exe as administrator
