Gns3 Error Failed to determine version of Dynamips Windows 8


Gns3 is not working on Windows 8:



When I start using GNS3-0.8.3.1-Standalone-64-bit on windows 8 64bit, I got the error “failed to determine version of Dynamips”. After long troubleshooting I am able to resolve this issue. I don’t know exactly why dynamips giving this message but from error wording it seems like that it is because of gns3 compatibly issue with windows 8.  


Anyway you can follow the below steps for resolving this issue.
1.       While troubleshooting with Dynamips.exe I notice that some .Dll files are missing on windows 8 in order to start Gns3 on windows 8. These are “Packet.dll” and “wpcap.dll” I copies these two files from my windows 7 machine to windows 8 and then test dynamips again and I got the positive result with message “Dynamips 0.2.8-RC3 successfully started “. You can download and copy these to files to C:\Windows\SysWOW64 on windows 8. If you have a windows 7 installed then you can also copy these two Dll files from same above location and can paste these into Windows 8.


2.       Hope this will resolve your issue if not then you add gns3.exe and dynamips.exe to firewall allow applications from firewall setting and test again.



3.       Also try to run gns3.exe and dynamips.exe in windows 7 compatibility mode from properties\ compatibility tab.

Please share your experience if your issue is resolved also if you have same issue with dynamips then feel free to ask any question.
