- Fixed an issue where the Mass Effect 2 launcher was being associated with files that have no extension.

I think you understood what my problem is. I mean was, the solution is here as follows,

1. Open regedit.exe
2. Backup these locations (you may export each of them);
- HKEY_CLASSES_ROOT\.
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.
- HKEY_USERS\S-X-X-XX-XXXXXXXXXX-XXXXXXXXXX-XXXXXXXXXX-100X\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.
3. The final one is your unique account (user) on that pc.
4. Now delete those locations (back ups are good).
5. Log off and log on again.

Henceforth the files with no extension (for example hosts file in C:\Windows\System32\drivers\etc\hosts) will not open with Mass Effect 2 launcher by default.
