Here is a truly trivial solution from the ST web page Peter BENSCH (ST Employee)

Normally, this problem should not occur on a PC or notebook that was purchased normally and not equipped with ST software for developing microcontroller applications. In this respect, the manufacturer of the PC/notebook would be the right contact person who would have to eliminate this problem.
However, if you want to help yourself, you could deactivate this typically unneeded software:
- launch "Device Manager"
- in the View menu, select "Show hidden devices"
- find the device associated with oem77.inf (it might done by selecting "Device by driver" in View menu
- right click on this oem77 - does it offer an option to remove the device? If yes, remove it.
- you'll maybe need to reboot the machine afterwards
We would be pleased if you would paste the result here and even more pleased if you would ask the respective manufacturer of the PC/notebook to remove the software from the standard installation.
