Error: couldn't execute "qwedt"

Hi,

I'm using Quartus II 64-Bit Version 10.1 with Altera U.P. Simulator Version 10.1

After I select File > New Simulation Input File, get the following error message:

error: couldn't execute "qwedt": no such file or directory.

Unfortunately I couldn't find a solution on the Internet. Can someone help me to fix this problem?

Thanks, best regards

    You may get this error when you try to launch the ModelSim® simulator from the Quartus® II software, using the NativeLink® integration feature.

    The Quartus II software requires the directory containing ModelSim executables such as vlog, vcom, and vsim to be in the PATH environment variable.

    For example, the PATH variable must include the following directories for the ModelSim SE software and the ModelSim-Altera tool on a PC platform:

    <ModelSim SE Installation>\win32

    <ModelSim-Altera Installation>\win32aloem

    Try running qwedt outside of qsim. If it installed properly, it should be in the <quartus installation>\quartus\bin or quartus\bin64 directory.

    If it's not installed there, you will probably need to re-run the UP installer.

    I had the same problem. Turns out you need to make sure that quartus_sh.exe is run from the altera\10.1sp1\ quartus\bin\ directory NOT the \bin64\ directory. Then it should be able to find the qwedt.exe just fine. Should work with quartus 10.1 as well (no sp1).
