Uninstalling FLEXnet Manager

I have been working with Flexera's FLEXnet Manager for a while now. It is the workable version of SAM-Report Lite that you can install to analyze your network license usage. Installing is quite the chore but not impossible if you have an experienced IT department. Uninstalling it is not so easy of you have a 64-bit server.

On a 64-bit server (ex. Windows Server 2008), there is no official uninstall tool so it has to be done manually if you intend on keeping the server. Here's what I did to remove it from our lab server (the production version is staying for obvious reasons...).

1- Stop all related services from the management console.
2- Backup all related folders.
3- Open a command prompt with administrative privileges (Windows Server 2008 only).
4- Navigate to the folder that contains the FLEXNET.BAT file for the Admin, Reporting or Agent module.
5- Type the following command: flexnet service uninstall
6- Repeat step 5 for each module.
7- Use an uninstaller such as RevoUninstaller to uninstall each program module (a WIN64 error will appear for Admin and Reporting. Just skip it).

There you go. Worked for me. A little bit of a pain but not impossible. Good luck!

LISP programming primer

I received a request from a client asking me to look at a LISP program he wrote that did not work correctly. I said yes and received the following code:

(COMMAND "osnap" "End,Mid,Cen,Node,Quad,Int,Ins,Perp")

LISP and all programming languages require a certain syntax when writing code for it to work. The above code did not conform to the needed syntax. Here is the corrected version:

(defun C:MYOS (/)
(setvar "OSMODE" 255)

The first rule of LISP, everything HAS to be in parentheses. The second rule is that each set of parentheses gets evaluated individually. The third rule is that all LISP functions must be defined with a DEFUN command.

The C:MYOS defines a function that can be launched from the command line by typing MYOS and then ENTER. The (/) indicates that no arguments or local variables are being used. The SETVAR command is used to modify AutoCAD variables like OSMODE which is responsible for the active OSNAPS in your AutoCAD session. Each combination of OSNAPS will have a unique code. The AutoCAD documentation explains this variable very clearly. The text following the semicolon is a LISP comment which is ignored by AutoCAD when running the function.

An alternative to this simple little function is to script the operation is a file like MYOS.SCR. In Notepad, type the following text with NO spaces at the end of each line and press ENTER at the end of each line as well.

Scripting is handy for some operations but can be tricky at times. The underscore + dash before the OSNAP command are used to internationalize the script (any non-english AutoCAD will recognize it) and to deactivate the dialog box so that the answers are sent as plain text.

In both scenarios, write your code in Notepad and then drag and drop the file into your AutoCAD session to load it. The LISP function must be launched on the command line but the script will run automatically if no command is already active.

Hours and hours of fun are possible when you start dipping into automation. Not for the faint of heart!!!

Happy coding!
