You could try the Squirt the Cat installer or try the DOS version in DOSBox. http://www.squirtthecat.com/games/leisure_sui … ry_7/index.html

Polish version doesn't have a DOS Installer so Sierra Installer from sierrahelp don't work. Jafa installer also doesn't work with Polish Version. I wanted to report it to him, but I can not register on his forum

You can try to email him.

But i don't know his e-mail

Used to be on his forum.

I can't register on his forum! So I can not find out what the email address is.

Looks like he has removed all contact information from the forum. One other alternative is to try ScummVM.

Polish version doesn't work properly from ScummVM 2.0 unfortunately. Earlier versions ScummVM not supported Larry 7

It should return the hash that can be reported to the SVM team to add support for your version.

Someone has already reported it on bugs.scummvm.org, but the ScummVM team has not reacted. Here:
https://bugs.scummvm.org/ticket/10125

Is this a fan translation?

No. This is a translation made in CD Projekt

Probably not an official Sierra release. If you can ID the various language related patches you should be able to drop them into an installation with the StC installer it should work.

This is official release for CD Projekt so i can't ID related language patches
