Thanks to all for your replies.

First, I put it in Program Files x86 when unpacking the zip file.

I can't be sure that QB64 was installed; because I planned to uninstall; but can find no sign of it to perform a Windows Uninstall.

However, I did find 4 entries in the registry that referenced qb64. Should I delete these before attempting to reinstall?

It appears that I have two ways to get qb64 into its own directory,
          Perform a Windows Move and move everything out from under Program files to its own directory - - -
          OR delete everything and reinstall from the extracted zip file.
          What procedure does the group recommend?

Also, is there a link to the install procedure?  I found a readme file in the zip; but the readme had little guidance.

What kind of install sequence can I expect?

Thanks again to all.

PC is an IBM clone running an Intel I5-4590 @ 3.3 gHz
8 gb RAM
2 TB disk
Win 10 64 bit

What do I do to get QB64 1.4 to run?

I granted full security control to the QB64 folders.

I tried to run QB64.exe
All I get is a screen that looks like a DOS window with the message
"press any key to continue"

A press of any key closed the window and nothing further happens.

What is it, that I'm doing wrong?

Many thanks
