Default Msieve can't find procrels

Was running an Msieve job when it crashed with this:

Code:
-> Running square root step ...
-> ./msieve -s 33373_189/33373_189.dat -l 33373_189/33373_189.log -i 33373_189/33373_189.ini -nf 33373_189/33373_189.fb -t 6 -nc3
-> Computing time scale for this machine...
-> procrels -speedtest> PIPE
Traceback (most recent call last):
  File "../factmsieve.py", line 2253, in <module>
    output_summary(NAME, fact_p, pols_p, poly_p, lats_p)
  File "../factmsieve.py", line 1911, in output_summary
    (ret, res) = run_exe(PROCRELS, '-speedtest', out_file = subprocess.PIPE)
  File "../factmsieve.py", line 350, in run_exe
    p = subprocess.Popen([ex] + args.split(' '), **al)
  File "/usr/lib/python2.7/subprocess.py", line 711, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1343, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory
The lattice sieving seems to have been completed. Is there a way to fix this issue and resume from the saved backup?

You mean "the python script cannot find procrels". Your factorization is complete; procrels is called by the script to do a little summary work/statistics on your factorization. Check your log file for the factors.

If you place procrels in the same folder as msieve and the lasieve binaries, the script will create a nice text file with your factors, the time taken in each stage, and a few other stats.

It is included with the GGNFS package. I have attached the windows version, zipped.
