After getting the error that I originally indicated, yesterday I performed a series of tests on the computer and I had to uninstall PF3 concluding that the error I got was caused by lack of space in the partition where I was installing the program.
Now, I installed it on another new partition, and everything seems correct, except that when I tried to activate the product, I get the message attached.
I thought that with the first error the registration of the program in the equipment was not carried out, when apparently, it turns out to be realized.
That is, since it was impossible for me to unlink the PF3 registry from my computer, I uninstalled the program as it was, resulting in the license blocking.
I clarify that I am not installing it in any other equipment, but in which I have always had it installed.
Can you give me a solution?
Thanks in advance.
