when i select the folder with the first .bin part , the installer don recogniize the file.
If all the parts are in the same folder as the install file, it you shouldn't need to select anything. It is possible that file is corrupt, and redownloading it may help.
First, though, if the game is still installed:
Are you shutting down all non-essential programs (especially anti-virus) before starting the game? Firewalls have caused conflicts (generally on loading screens) and overlays from graphics tweaking/monitoring programs or chat programs have also caused issues.
Try exiting out of Galaxy, and starting the game directly from the '..\Divinity Original Sin Enhanced Edition\Shipping\EoCApp.exe' program file, by right clicking and running as administrator.
If you have any generic or obscure USB controllers (or other devices) plugged in, try disconnecting them. Crashes on startup with faulting module names of ntdll.dll and EZFRD64.DLL, can (particularly for the latter) be related to USB controllers or PS2 to USB adapters (for various games).
One person reported a crash using the Wii U controller adapter in Dinput mode, which could be fixed by uninstalling the drivers (though that also eliminated rumble support).
Another reported this issue with a USB hub, and Windows 10 in particular seems to have more problems with USB devices that are not fully recognized.
Check for updated graphics drivers, and Windows updates in general.
For Windows 7, please make sure you have Service Pack 1 installed. That is the minimum required version of Windows (64 bit).
Try verifying local files, if you didn't already do so: in Galaxy, select Divinity: Original Sin Enhanced Edition in the left column, then click on the More button, and in the Manage menu select 'Verify / Repair'.
Especially if you have a relatively high desktop resolution, you can try temporarily lowering it, to limit what the game will auto-detect. If that allows the game to start, you can then exit and restore your desktop resolution. With V-sync disabled in the graphics options, the game may be ok at the higher resolution.
If you check the Event Viewer, does that give an error code or 'Faulting Module' file name that might help identify the cause of the crash?
- click Start (or WinKey-R), then type "event viewer" into the search box. in Windows 10, 'event' should bring up 'View event logs'.
- after starting the Event Viewer, expand 'Windows Logs' in the left column and select 'Application'
- in the center column, look for a recent error (maybe sort by Date and Time) for the game
- check the information under the 'General' tab below the list of events, starting with "Faulting application name..."
If you get a VC related dll error when trying to start from the executable, try manually installing the 2013 redistributable (normally GOG should install this, if required, when you install the game).
C:\Program Files (x86)\GalaxyClient\Dependencies\__redist
or on the page for the latest downloads, you can scroll down a bit to get the 2013 link. https://support.microsoft.com/en-ca/help/2977003/the-latest-supported-visual-c-downloads
Try browsing to the '..\Documents\Larian Studios' folder and delete the 'Divinity Original Sin Enhanced Edition' subfolder.
This folder contains the saved games, configuration files and a level cache folder. Normally I would suggest renaming the folder for troubleshooting purposes, but if you don't have any saved games that isn't an issue.
Next, extract the replacement folder from this download
into your '..\Documents\Larian Studios' folder, and see if that will let you start the game.
The graphicSettings.lsx file is set to 1280x720 Windowed mode, Very Low quality preset, which you can change in the options (manually, or hit autodetect) if this gets the game to start.
If that doesn't help, you can delete the downloaded My Documents D:OS folder.
