Hi,

I'm using SW2011 SP4EV 64-bit on Win7 64-bit, all are en Italian language.

When I double click on a part via windows explorer the message that I attach came out.

I don't have the problem of two SolidWorks.exe istances, but only this message and the part is open correctly.

I tested SW 32-bit on Win7 32-bit and the problem doesn't came out.

Ideas ?
