<div>Hi Stefan</div>
<div> </div>
<div>Yes, I checked whether I have versions of cygwin1.dll other than the one from the X2Go installation.</div>
<div>I ran the command you sent, it found the X2Go cygwin1.dll and generated some error messages that the name of some directories is too long, if I supress the errors the only cygwin1.dll is the one from X2Go:</div>
<div> </div>
<div>
<div>Directory of C:\Program Files (x86)\x2goclient</div>
<div>13.11.2014 15:45 3'247'117 cygwin1.dll<br/>
1 File(s) 3'247'117 bytes</div>
</div>
<div> </div>
<div>I even tried to create c:\cygwin\bin directory and copy cygwin1.dll into it, but it didn't help.</div>
<div> </div>
<div>Cheers</div>

Did you follow the instructions in the error message?<br/>
<br/>
"This problem is probably due to using incompatible versions of the<br/>
cygwin DLL.<br/>
Search for cygwin1.dll using the Windows Start->Find/Search facility<br/>
and delete all but the most recent version. The most recent version<br/>
*should*<br/>
reside in x:\cygwin\bin, where 'x' is the drive on which you have<br/>
installed the cygwin distribution. Rebooting is also suggested if you<br/>
are unable to find another cygwin DLL."<br/>
<br/>
While I wouldn't exactly recommend deleting all the versions you can<br/>
find right away, please do report back all the directories that contain<br/>
a cygwin1.dll.<br/>
<br/>
I'd actually prefer to use the commandline for that, because it allows<br/>
for easier copying and pasting:<br/>
<br/>
Open a cmd.exe and type:<br/>
<br/>
dir C:\cygwin1.dll /s >allmycygwins.txt<br/>
<br/>
and attach the resulting allmycygwins.txt file to your next e-mail to<br/>
this thread.<br/>
<br/>
I know for sure that I've used a 4.0.5.2 build of X2GoClient on Windows<br/>
10 without issue, so I'm actually suspecting a problem with your<br/>
individual installation (just like the error message suggests).<br/>
<br/>
Kind Regards,<br/>
