ERROR "refprp64.dll could not be found"

1. First, I created a new folder 'work' in Disk 'F'.

2. Then I copy the 'REFPROP' folder under the 'work' folder.

3. I copy REFPRP.dll and REFPRP64_thunk_pcwin64.dll in the folder of 'REFPROP'.

4. I put refpropm.m, rp_proto.m and rp_proto64.m in the 'work' folder.

When I finish written the program, and have set the working path and saved the file as 'F:\xx\xx\work', then run the 'a.m' program, there is still error:' refprp64. DLL can not be found. Please edit the refpropm. m file and add your path to the ABO lines.'

Hi,

This missing DLL, as well as several other matlab files, must be downloaded separately from the primary installation of REFPROP, as mentioned in the 'MATLAB wrapper of REFPROP' Installation instructions.

Please click the hyper-linked files on that webpage to download these files and move them into your REFPROP installation folder (c:/Program Files (x86)/REFPROP).

Thank you very much for your answer, my problem has been solved by rewritting the refprop.m.

hello,what you did in refprop.m file , iam facing same issue.

[Xia Zhou]

you may change the file path in the "refprop.m" to your "xx.m" path. For example, the file path in the "refprop.m" may be "c:/Program Files (x86)/REFPROP", you can change it to "C:\Users\Desktop\work" (the file path that your .m file is).
