The mandatory version to be used for Microsoft RDP Client on android devices is: 220.127.116.113
Newer RDP client versions do not work with Produmex Scan! Previous versions might work, but should be upgraded to this one.
In some cases, no barcode is transmitted to our software, in other versions, non-printable or special characters are discarded. We also have reports of other issues with the newer Microsoft RDP versions.
It is possible to obtain the correct version from our FTP server, at ftp://ftp.produmex.name/Install/Microsoft and download "com.microsoft.rdc.android_18.104.22.1683-74_minAPI16(armeabi,armeabi-v7a)(nodpi).apk".
This refers only to the Microsoft Android RDP client. Other software manufacturers have not been tested.
