Viewing post in Can't install app due to missing .dll file
i just donload the missing file here : https://fr.dll-files.com/download/1e0d62c34ff2e649ebc5c372065732ee/libwinpthread...
And add it to C:/windows/sysWOW64 folder, and it works ;)
(syswow64 is for 64bit version of windows, if u got 32bit version, the folder is : system32)
