QGIS 3 won't open in Windows 10 pro, how to fix?

Question

I have installed QGIS 3 in Windows 10 pro 64 bit, but it won't open the GUI. This is the error:

And then this:

Some specifications:

I had installed QGIS 2.18, and it ran perfectly.
I had installed the latest QGIS 3 under "Program Files" folder and also in the root C:.
I installed with OSGeo4W software and with QGIS desktop .exe, load to QGIS web page.
I run other software like PostgreSQL, GeoServer, GeoNetwork and ArcGIS  on the PC.

The comments were very helpful and I can now open QGIS 3 without a problem. I have done it in two ways:
With the help of Mapperz, look for Qgis-rel-dev-g 7.4.0.bat inside the installation of QGIS 3 and this run.

With the help of Techie_Gus, I can run QGIS 3 without problems from the OSgeo4w terminal.
Both ways work well.

I don't consider the language likely to be the problem, if not more the path as Techie_Gus said , because I did run QGIS 3 in another session.
I'll be trying to do what Xunilk says, to define the specific error.
The main problem was solved, and I could run QGIS 3, also, I think it is a path problem perhaps in the registry of W10, I will checked the environment variables.
