Error "VTECRM Network service fails to create your license (err 4)"

Hi, I got the above error when trying to re-activate my 4.5 installation

Thanks in advance,

Lucio

I tried to update to VTE 15.10 and I get the same error on activation.

Please help!

Lucio

The error log contains the following message:
....
[Sat Dec 10 13:13:23 2016] [error] [client ::1] File does not exist:
C:/vtecrm/htdocs/modules/Users/CheckPasswordCriteria, referer: http://localhost:8015/modules/Morphsuit/RequestMorphsuit.php?morph_mode=installation
....

The file exists and I checked permissions, any idea?

I got the same error too.
Someone could help?
Thanks.

Hello Administrators, I have a 10.05 installation on Ubuntu 12.04, suddenly a request of configuration for the admin credentials was appeared.
If I try to register than I have the same problem with a "VTECRM Network service fails to create your lincense (err 4)"

Anyone found a solution for that issue ?!?!
Greetings

P.s. in attachment you can find a screenshot of the request of activation.
