Ansys mechanical APDL problem.
 

Hi :)
I installed ansys 12.1 on window 8. The workbench works fine, but when I run "ansys mechanical apdl", this error appears on the screen:

"Ansys is not istalled"

What's going wrong? I think that installation procedure was done correctly.

Moreover, if I run "ansys mechanical APDL product launcher" another error appears:

The ansysli_util file, which is required to determine which products are to be displayed in the license dropdown list, was not found or is not executable.
Path: C:\ANSYS Inc\v121\ANSYS\..\..\shared files\licensing\winx64\ansysli_util.exe.
This is a fatal error,existing

Help me please, and sorry for my english :D
