Thanks for reply, I've installed it again but there is no log file or folder anywhere, neither on that folder nor on my pc..
When I start visual studio, in the output tab there is three of this error: The Visual Studio HTM Editor Package ({1B437D20-F8FE-11D2- A6AE-00104BCC7269}) did not load because of previous errors. For assistance, contact the package vendor. To attempt to load this package again, type 'devenv /resetskippkgs' at the command prompt. And nothing change if I start visual studio whit this command "devenv / resetskippkgs"..
