Hi, I recently downloaded Burai for the first time and tried to run it on my Windows PC. Accoring to the instructions here it seems like it would be sufficient enough to just extract the ZIP and launch the Burai executable from the bin folder. I tried it on three different PC's now, all have the latest update of Java. Whenever I simply click any given example CIF like TiO2 and try to calculate something like the SCF or the bandstructure and launch it it will immediatly stop the calculation and give me the same error report: ERROR in running the project: C:\Users\####\.burai\####
COMMAND: C:\Users\####\Desktop\BURAI1.3_Windows\exec.WIN\mpi\mpiexec.exe -n2
C:\Users\####\Desktop\BURAI1.3_Windows\exec.WIN\qe\pw.exe -in espresso.in I don't know do I have to set-up something or launch something when I install the software? If I click those error files it gives me: For mpiexec.exe:
It opens up a command prompt very quickly and then closes it again.
For pw.exe:
It bascially says that the Code cannot be run as msmpi.dll was not found.
But msmpi.dll is in the folder as well....
Any suggestions what I have to do here? Is it because I just start off randomly perhaps? Because I only wanted to try how the software behaves before I get into actual calculations and simply clicked the one I was interested in, the SCF and the band structure. But perhaps you can't simply start right in the middle but have to prepare the files first. I don't know...
EDIT:
I also tried downloading Burai 1.2 and get the exact same error messages simply with 1.3 swapped for 1.2.....
So I removed Version 1.3 and installed Version 1.2 and then directly moved the folder to C: as described in the installation manual. I set the path from mpiexec.exe to mpirun like I found on YouTube and also downloaded the latest version of msmpi.dll from Microsoft. After that I was able to at least open the pw.exe manually and it opens now in a seperate command promt saying:

So it seems like there is no issue with the pw.exe file anymore. Launching Burai 1.2 and starting a random SCF calculation I won't get the first error message anymore about the mpiexe.exe. Also switiching the command back from mpirun to mpiexec doesn't seem to cause any issues. I guess this first error message has been resolved by moving the folder into the C drive directly. However I still get the second error message with the pw.exe although it seems to work fine.
I also made sure to only save the files in the .burai folder under users as there seems to be an issue once you save it elsewhere.
At this point I'm pretty much clueless again about how to continue.
