Hello all, glad to be here.

I am a Computer Manager at an institution, and as such responsibility falls on me to keep professors connected and happy...

Anywho, I have a professor running win7 on an older laptop, and upon installation, we have found his (fresh) install of ANSYS 2019R1 unable to pull a network license over Cisco VPN. The strange part is, a 2018 build of ANSYS is perfectly capable of doing so under the same conditions.

Both work fine when on-site, as well.

 

When starting 2019R1 Mechanical APDL, there is an extended hangtime (up to a minute in some cases) before the applications states it is unable to pull a license.

 

I have:
   Ensured telnet/pingability of client pc to the license server,

   checked/added firewall exceptions,

   removed any installations older than 2018,  and

   fully reinstalled 2019R1 to no avail.

 

Has anybody encountered a similar issue?

 

While I understand win7 is deprecated, any direction is greatly appreciated.

 

Regards,

 

-Mason

Hi Mason,

What version License Manager are you running on the License Server?

It may be one of two things:

1. License Manager is older allowing 2018 to run. (Updating the ANSYS License Manager software on the License Server should fix this)

2. The license file you are using is not current in TECS. (Meaning it will not allow newer programs to run)

You can check the following for License debug information that may point to the issue:

The directory:    %TEMP%.ansys

Will have licdebug files in it.

Check these files for any errors.

Please let me know if this helps!

Best,

Geo

Hello Geo,

 

My server is running the 2019 R1 License Manager, which seems to function fine for all the lab computers running 2019 R1. I will have the professor bring his laptop in so I can comb through the license debug information. I'll keep you posted.

 

Regards,

Apologies for the delayed response,

The "licdebug.ANS_INFO.193" file seems to be the most informative:

This log seems to be old. Does this align with the time that the professor encountered the issue ?

On the license server machine, open up the installed license file(s) , default under, C:Program FilesANSYS IncShared FilesLicensinglicense_files*.lic, then check the first line of each installed license file, you will see SERVER

Use that exact with ping command. Try pinging it from the license server machine and client machine, do you get the same IP ? If not, you have to correct this. You can modify hosts file on client side and see if it can force to resolve to the IP that server sees itself. 

Also, on the client side, check if it specifies the server with the exact same . If not, check if that resolves to the same IP.

Thanks,

Win
