[TRNSYS-users] file permission problem with TRNSYS/genopt

[Matt Duffy]

Ben,

Please make sure you're using GenOpt 2.1 and NOT GenOpt 3.x. I believe
that is the error when using that version of GenOpt. You should be able to
download GenOpt 2.1 at the bottom of the following site.

Please let me know if you have any further issues.

Best regards,

Matt Duffy

Subject:[TRNSYS-users] file permission problem with TRNSYS/genopt

Hi,
I am running TRNSYS on Vista with GENOPT in order to use TRNOPT.  I have it
all configured for my system, based on the Example.  I set it running, it
runs the first simulation fine but then I get the following error:

Error message:
**************
genopt.lang.OptimizerException:
Program error. Attempted to delete non-temporary file.
GenOpt terminated with error.

Jeff at TRNSYS suggested it was a file permission problem with Vista, so
I've tried a variety of things, running with Admin rights, changing
permissions on TRNSYS/genopt folder trees to 'full control', turning off
User Account Control, to no avail.  Another suggestion was to move it out of
the 'Program Files' folder, I uninstalled genopt and TRNSYS and reinstalled
them in a different (non-system) directory, but still encounter the same
problem.

Next I dug out an old very slow XP laptop and installed TRNSYS et all on
this, eventually getting it running but with the same error!

I'm tearing my hair out slightly, up against a deadline now and wasting
hours trying to get the TRNOPT simulations running with no progress.  If
anyone has any advice or has seen this please get in touch, either via
mailing list or on ben @ mendipclimb.org.uk

Jeff - I guess you'll read this, any further advice appreciated, I'm just
posting here as I guess you won't see this until Monday now

many thanks,
Ben
