STVD 4.3.12 vs ST-Link V2, connection problem

[Sisto Zànier]

Hi everyone,

after solving a problem on Windows 7, I can no longer use ST-LINK/V2, or STM8-Discovery, for debugging via STVD (see version on attachment 2).

I've verified that both ST-Link and STM8 Discovery work correctly and in fact with these tools I can program through STVP, the micro STM8L used for my projects.

Instead, at every attempt to connect ST-LINK / V2 or STM8 Discovery, to my targe, it gives me the message of attachment 1.

I have correctly updated the ST-LINK/V2 firmware and completely uninstalled sttoolset and then installed it again, but this did not solve my problem.

I kindly help someone who has had similar problems.

Thanks to everyone.

Finally running same version of STVD on different machines always using same O.S., I've found an incompatibility of Windows 7 Professional SP1and STVD Swim debug using ST-Link/V2. Also with uninstalling and reinstalling again sttoolset 43, DAO350 nor DAO360 drivers does not more be installed.

Now I don't know how to solve this problem. Anybody can help mi with suggestions or solutions? Please...
