Modelsim PE Installation issue

Hi,

My company owns ModelSim PE 10.5 edition which is a full feature tool. I

am getting the following error messages:

Error: Error: Can't launch the ModelSim software -- the path to the location of the executables for the ModelSim software were not specified or the executables were not found at specified path.

Error: Error: You can specify the path in the EDA Tool Options page of the Options dialog box or using the Tcl command set_user_option.

Error: Can't launch the ModelSim software -- the path to the location of the executables for the ModelSim software were not specified or the executables were not found at specified path.

Error: Error: NativeLink simulation flow was NOT successful

I have put the correct location of the executables in the TOOLS - OPTIONS -EDA_TOOLs_OPTIONS

L:\MODELSIM\win32pe\modelsim.exe

I have also tried

L:\MODELSIM\win32pe\modelsim.exe

Any suggestions to integrating this full tool set??

Thanks!!
