Windows – difficulty installing rdpwrap on windows 10 (to get multiple remote desktop connections)

remote desktopwindows 10

RDP Wrap helps to allow for multiple connections to remote desktop on eg Windows 7 or Windows 10. I tried to install rdpwrap going to https://github.com/stascorp/rdpwrap/ and I tried running the MSI under "releases", RDPWInst-v1.6.2.msi and it gave some error, and when I tried to reinstall it and I got no error and it wasn't clear what i'm meant to run or what if anything was intalled. And no concurrent/simultaneous remote desktop either.

Then I tried to uninstall it and it prompted me to allow c:\windows\installer\c4d5253.msi to run. I said yes. And it said "There is a problem with this windows installer package".

Note- I have a solution and will post an answer.

  • If you go to https://github.com/stascorp/rdpwrap/ there are three ways one may try to download the program. There's downloading the code, from the code tab. Or, under the releases tab, there's downloading the MSI file. Or, also under the releases tab, there's downloading the zip.

    Out of those methods, the method I used that worked, was to go to the releases tab, and download the Zip there. So, not the code tab, not that zip. And not the MSI under releases. But the zip under releases. RDPWrap-v1.6.2.zip

    Then, extract that zip to some directory. Start a cmd prompt run as administrator. So an administrative cmd prompt. (from there you can run install.bat that's better than being in a regular cmd prompt and right clicking install.bat and doing runas on the bat, 'cos apparently that can be buggy).

    Extracting the zip produces

    C:\rdpwrap>dir
     Volume in drive C has no label.
     Volume Serial Number is C811-E477
    
     Directory of C:\rdpwrap
    
    03/05/2020  15:34    <DIR>          .
    03/05/2020  15:34    <DIR>          ..
    03/05/2020  15:34               458 install.bat

    03/05/2020  15:34               249 update.bat
                   6 File(s)      3,602,876 bytes

    You needn't run RDPWinst.exe directly, the bat files run it with the right switches/options.

    Run install.bat from an administrative cmd prompt

    C:\rdpwrap>install

    A major thing that did is made this directory and these files

    C:\Program Files\RDP Wrapper\rdpwrap.ini
    C:\Program Files\RDP Wrapper\rdpwrap.dll
    

    You can run uninstall.bat but then you'd have to run install.bat again

    But you want it installed so run install.bat

    So you have those two files now in \program files\rdp wrap

    You could try

    C:\rdpwrap\rdpconf
    

    That will tell you if your version of c:\windows\system32\termsrv.dll (which came with your OS), is supported by your c:\program files\rdp wrap\rdpwrap.ini

    See what version your termsrv.dll is (rdp wrap will not and has not replaced this file).

    You can use right click..properties, or as I have for the sake of this post, the command line

    C:\rdpwrap>wmic datafile where name="c:\\Windows\\System32\\termsrv.dll" get version
    Version
    10.0.17134.706
    

    You can check yourself whether it's supported by your ini file.. either in notepad and edit..find and see or

    C:\rdpwrap>find "10.0.17134.706" "c:\Program Files\RDP Wrapper\rdpwrap.ini"
    
    ---------- C:\PROGRAM FILES\RDP WRAPPER\RDPWRAP.INI
    
    C:\rdpwrap>
    

    not there

    There are some versions there in this case but not my version

    C:\rdpwrap>find "10.0.17" "c:\Program Files\RDP Wrapper\rdpwrap.ini"

    ---------- C:\PROGRAM FILES\RDP WRAPPER\RDPWRAP.INI
    [10.0.17004.1000]
    [10.0.17017.1000]
    [10.0.17025.1000]
    [10.0.17035.1000]
    [10.0.17046.1000]
    [10.0.17063.1000]
    [10.0.17004.1000-SLInit]
    [10.0.17017.1000-SLInit]
    [10.0.17025.1000-SLInit]
    [10.0.17035.1000-SLInit]
    [10.0.17046.1000-SLInit]
    [10.0.17063.1000-SLInit]
    
    C:\rdpwrap>
    

    rdpconf.exe will say "not supported"

    Unfortunately the ini file bundled with the project is old.

    There is an update.bat but it gets an old ini file that doesn't support many termsrv.dll versions.

    So you have to go to the github page and look at issues or pulls and see if you can get an ini file with your build version in it.

    In order to replace c:\program files\rdp wrap\rdpwrap.ini you will have to stop the 'remote desktop services' service, so as to unlock the ini, then replace it, then start it. And you see from services.msc that it's called TermService. You can do sc queryex termservice to see if it's running or not. s (sc queryex is a bit better than sc query 'cos sc queryex shows pid). And you can do net start termservice, net stop termService, and taskkill it if it gets stuck 'stopping'.

    Then you can run rdpconf.exe see if it says successful.. (as opposed to 'not supported'). You could even use rdpconf before (re)starting terminal services

    And then you can do rdpcheck, and see if that says "limited connections" , or if it just works. (or you could test with mstsc, but rdpcheck is very quick to test)

    And then you know and hopefully it will work for you.
