License Error

[MS_Santos]

I'm with license error every two days pops up even clicking on does nothing, I need to restart the machine to get back normal. I went over the installation, checked the MAC of the license next to the machine, removed the Antivirus and released the Windows firewall

 Hi,

Article - "Error “FLEXnet licensing error: "(-61), Cannot read license file data from license server system" while launching applications configured with PTC FLEXnet Admin License Server": https://www.ptc.com/en/support/article/CS27950

Hi,

you have provided little information.

Q: Is FLEXnet installed on the same computer as Creo ?

Note 1 : You do not have to restart computer. Simply stop/start lmadmin_ptc service to "refresh" license.

Note 2 : The computer where FLXEnet is installed must not go into sleep mode, when you stop working.
