Two licenses for the same computer

Greetings

I want to get another license for this, to use the proxy checker. Will it work if with one I will check the proxies automatically for google search, and the other I will use to check automatically that list if they are anon?

Fairly sure SER uses a mutex to ensure only one copy is running. Even if this is wrong, there are numerous free proxy checkers available, a second copy of SER is overkill.

What exactly are you trying to acheieve?

I use two indexers now, with one I check automatically proxies for google search, second one checks anonimity, and gscraper scrapes for links. Problem solved. Those indexers are installed on two users on the same computer. Gscraper is installed on one of these users.
Everything is automated, I only have to take the links and verify them in gsa ser. Although I think I will automate that too.
