chimera.uchime crashes with the following error message:
“This application has failed to start because cygwin1.dll was not found. Re-installing the application may fix the problem”
I am running 32bit v1.22.0 on windowsXP (could not get mothur to run on ubuntu 11.10).

Then it crashes. Do I really need cygwin here? Can’t believe it. I actually have cygwin installed. Any ideas?
Hello! I am also having a problem with the cygwin1.dll being missing error. I am running the same batch file on two different computers, both computers having Windows7, but the error appears on Computer A but not on Computer B. At first I thought this might be an issue relating to the version of MOTHUR, but I tried the batch file on both 1.22 and 1.23, and either MOTHUR executable works for Computer A and neither works for Computer B (ie, Computer B always gives the “missing cygwin1.dll” error). I don’t know of any significant differences between the two computers - in fact, they were both clean installs of Windows7 as of last week - other than that Computer A is a desktop and Computer B is a laptop (Lenovo ThinkPad E420).
I found a work-around! Not a fix, but a “good enough.”
Get Cygwin. Copy all of the .dll files and slap 'em into your folder with the MOTHUR executable (if you just put in cygwin1.dll then it will just ask for yet another .dll). I haven’t tested which subset of the .dll files is required, but by putting them all in there I was able to run chimera.uchime and finish my work. I am the first to admit that this is NOT an elegant solution.
I can’t help but wonder if the difference is related to the version of Windows7 on the two machines that I have been using - chimera.uchime is working on Enterprise but not on Professional. Thoughts? Better solutions?
