Hi Pedram,
Did you install the redistributable libraries (Visual Studio C++ and Intel Fortran)?
https://windows.lbl.gov/redistributable-packages
Also, are you doing all the procedures (installing, working) as Administrator?

Kind regards,
Zugur

Hi Zugur,

yes i did all of them. and it was working before probably it has some conflict with visual fortran and visual studio that i have installed recently.

If you installed other visual studio fortran and visual studio libraries, you may need to reinstall the ones linked on the THERM download page.

If THERM was running before, and isn't now, then something changed on your computer. 

The file THERM is trying to access is on Program Files x86.

Maybe something changed about permissions -- try running THERM as Administrator, which should give you permission to access that folder. 

Also, if you have permission to access that folder, make sure that gasses90.dll is actually there.

Yes it should be because of installing vs2015 and visual fortran.
The file is there and i run it as administor also but still didn't eork.

[Robin Mitchell]

Did you need to install those versions for some other software? I think they are older versions than what THERM needs.

[pedram ayyobi]

That's for programming with fortran. I need to check them all again. Just so strange

[Robin Mitchell]

I will check with our programmers to see if there is a way to have both installed and used for different cases, possibly through the registry.

Ok, thanks.
