err1501 The process cannot access the file because it is being used by another process.

[Akronae]

After installing ERAM, with no further instruction from the installer or github, I try to execute C:\ERAM\install.bat with an administrator CMD and I get this error:

C:\ERAM>install.bat
Device node created. Install is complete when drivers are installed...
Updating drivers for *err1501 from C:\ERAM\eram.inf.
devcon failed.
The process cannot access the file because it is being used by another process.
        0 file(s) copied.

I tried to restart my computer, still the same error.
Tried to delete all the files in C:\ERAM and it worked so I guess the file that cannot be accessed is somewhere else.

How should I install this software properly?
