Mathcad Prime 3.0 CU license issue

I have Mathcad Prime 3.0 installed and have a floating CU license, but maintenance has expired in 2014. I was issued a new license to remove the expiration dates, but still when I open Mathcad Prime, it only opens express. Any ideas what might be going wrong?

Hi,

in the past when I had Mathcad Prime 2.0 installed, there was a file C:\Program Files\PTC\Mathcad\Mathcad Prime 2.0\Doc\en-US\Mathcad_Prime_Installation_Guide_en-US.pdf. I hope you can find similar file in your installation.

In my file following information was included:

    Thank you Martin,

    This is as big help.  In my case, I have a floating license, and it seems I need to re-establish a working

    FlexNet Server.

    When I run the Installation Assistant, by pointing it to my license file directly it authenticates the file and then hangs with a status of "Installing License Server"


    Not sure if you have come across this. I seem to recall having this difficulty in the past, but alas cannot remember how it was resolved.

    Thanks again for you help, and have a great weekend.

    Hi,

    OK, you have floating license.

    If you open license file look at PTC_HOSTID in SERVER line. The value assigned to PTC_HOSTID is physical address of network card. Does it belong to your computer ?

    If YES, then FLEXnet is installed on your PC. Do you know FLEXnet installation directory ?

    If YES then you will find license.dat file in licensing subdirectory.

    Now you can update the contents of license.dat file using your new license file. I use following procedure:

    1. open license.dat file in Notepad
    2. open new license file in Notepad
    3. select SERVER and DAEMON line in license.dat file, press CTRL+C
    4. select SERVER and DAEMON line in new license file, press CTR+V
    5. in new license file, press CTR+A, CTRL+C
    6. in license.dat file press CTRL+A, Delete, CTRL+V
    7. save license.dat file
    8. close and don't save new license file
    9. restart PC
    10. start Mathcad Prime and apply procedure mentioned in Mathcad_Prime_Installation_Guide_en-US.pdf
    11. Specify Server (name of your PC) and Port (7788)
