Thanks for your interest.
I'll try to fill you in. Windows 7 Home Premium SP1 64 bit 4GB Ram Toshiba Satellite AMD E300.
When I try to run the exe in Folder Blue, the mouse pointer starts to indicate activity and then reverts to being just a pointer. End of deployment; no messages. If I change the folder name to, say, BlueT, the exe will run; if I revert to Blue, it won't run. In the post above, I mention that deleting the Blue Music folder had no effect on whether the exe in Blue would run, it still wouldn't. But, then I did a through search for any remnants of Blue Music; shortcuts, start menu entries etc. Once all those had been removed, the exe in Blue now runs as expected. So this suggests a rule in Windows 7 about folder naming that is new.
BTW, these are applications I developed.
