if theyre the older ones they need the unlock file, if its not reading those its because the exe doesnt have permission to read external files so they need to be ran as admin
its specifically Damsel Quest, The Trade and Deepground Lab
i just tried running Damsel Quest as an admin but it did not work
Damsel Quest and The Trade are having problems with "unsupported compression algorithm" while Deepground Lab has a problem with "No manager for installer unknown"
also sorry about this realms
