Hmmm download the game again I guess.
You should have the language files allready.
Sadly some bgt games are detected by some antivirus programs as malware.
On win7 I just exclude as they become a problem.
However on win10, I am seriously thinking of having a folder for stuff that I know is not malware called unprocessed or something, I will first run the file to see if it is in fact malware normally but if its a game I will put it in a temperary location where I can run without it being scanned then later put it in its own folder and exclude it.
Sadly I think a lot of script based code is flagged by default as harmfull probably because it potentially could be, that includes autoit, java and bgt, and at one stage a certain version of the nvda compilers for python was detected as a virus.
It doesn't happen for all games though so for all we know it could be a certain thing or function.
I had this with a chinese installer once for a game, it always said it was malware, the game ran fine.
I got round that by making the installer in innosetup.
I do wander to be honest how much it is to get a personal certifficate, no one will be able to afford any professional signing certs for well their pro projects especially if they are a small company.
Then again all we need is a certifficate or something that says that we are a trusted company and not anything untoward.
However there must be a way.
I do wander if you could use a gpg or other key to sign your stuff for free or something or low cost.
It wouldn't give us the flexability of say a signed whatever with all our blurbs, contact details company name, email address, etc, but I do wander what a minimal cert would cost.
It doesn't even have to be for uac or admin access it just needs to be a dummy file to say stuff is ok.
Then again if hackers could do that then you would have a problem.
And in addition to certifficates expiring they do get stolen or companies do mangle releases from time to time.
I do wander though if an indevidual cert could be made, we don't need it to do much except get past security really.
I do wander how those at nvda do it as nvda needs to run in uac and a few other things and nvaccess is opensource.
