Warning/Disclaimer ityadi: Assuming that you, the person facing this problem, owns a licensed, legitimate copy of the software. You got no business taking my name when the aunty-piracy overlords throw you in ze gulag for using warez – Comprende?
The problem lies not with the Software [Unigraphics NX], but with its license manager that is supposed to run as a service in the computer. It enables you to run Unigraphics NX on workstations that access the license manager before running. However, the license mangers of Unigraphics NX4 and Unigraphics NX3 [and possibly other older versions] fails to run as a service in Windows 7 [and also Windows Vista], thereby terminating the installation. As a result Unigraphics NX will refuse to work even if installed on your workstation.
There is a workaround though. Installation of the License Manager terminates when it tries to start the file – meaning the file has already been transferred to the Hard Disk – and when it fails to start, it informs you so, after which you cancel the installation process.
- After you receive the message saying that installation failed to start the service, do not click Cancel immediately.
- Instead, go to the following location [or the path you had selected for installing the license manager – this one is the default location]:
C:\Program Files\UGS\License Servers\UGNXFLEXlm
- Copy all the files that you find inside the folder UGNXFLEXlm.
- Create a new folder somewhere else, say the root of your c: drive, and name it suitably – say UGNXlm, and transfer the files you had copied into the newly created folder.
- Now you may click on the Cancel button, I had asked you not to click on earlier.
- Open Notepad and copy-paste the following into it [uncheck Word Wrap (Format>Word Wrap) to be safe]:
echo @C:\UGNXlm\lmgrd -c c:\UGNXlm\ugnx3.lic -l C:\UGNXlm\log.txt >c:\UGNXlm\nx3_server.cmd
where, ugnx3.lic should be replaced by the .lic file name of your license file. You may also replace nx3_server with a name of your choice.
- Save that notepad file, giving it a name “nx3_server.cmd” including the double-inverted commas as shown. The file name [here, nx3_server.cmd] should be same as the name you had used inside the Notepad file [.cmd].
- Once done, it will create a new file nx3_server.cmd [in my case].
- Before starting Unigraphics, run this .cmd file. After this, Unigraphics NX should run without issues.
- If, unlike me, you happen to use Unigraphics frequently, then you may copy a shortcut of the .cmd file [nx3_server.cmd] to the startup folder. License manager will start the moment you log into Windows.
If you also happen to own a licensed copy of Unigraphics NX5 or beyond, then you could copy the lmgrd.exe file from there and use it to replace the file having the same name in NX4.
