Could not find rtl_work.TB.vhd

Thank you for the effort.

I typed:

...

vcom -work rtl_work fixed_float_types_c.vhdl

and it returned:

# Model Technology ModelSim ALTERA vcom 10.0c Compiler 2011.09 Sep 21 2011# ** Error: (vcom-7) Failed to open design unit file "fixed_float_types_c.vhdl" in read mode.# No such file or directory. (errno = ENOENT)# E:/altera/11.1sp2/modelsim_ase/win32aloem/vcom failed.

I moved from desktop to D: and tried again but failed with the same code, i try giving them write licence to all project files and folders, also with that failed.
