How to solve Naviswoks Network License unable to get from network in VPN connection?

If your user from remote site office report you that they cannot user their Navisworks with VPN connection and faced with below error, you can settle with the solution mentioned in following.

"A valid license could not be obtained by the network license manager.

Error [1.5.-15]"

"A valid license could not be obtained by the network license manager.

Error [1.5.-18]"

1) Right-click My Computer. Click Properties.
(for Vista and Windows 7, click the "Advanced system settings" link.)
2) In the System Properties dialog box, click the Advanced tab.
3) On the Advanced tab, click Environment Variables.
4) In the Environment Variables dialog box, under System Variables, click New.
5) In the New User Variable dialog box, enter FLEXLM_TIMEOUT for the name and 10000000 for the value.
6) Click OK to close each dialog box.
7) Launch the Navisworks application.


If you are able to obtain a license, the value of 1000000 microseconds (1 second) is sufficient. If you still cannot obtain a license, repeat the procedure; increasing the value in 1000000 microsecond increments until you are able to obtain a license from the license server.

Although I only talk about Navisworks in this post, you still can use above solution method for other Autodesk Application as well.


May you all be happy.
(Be knowledgeable, pass it on then)
