For fixing "File is changed W[2007] L[2] crossfire.exe" error.
This is a common error that's why I feel it's necessary for me to Post this.
The Usual Fix;
1. Open CF Folder
2. Look for version.ini file and Open it.
3. Change/Edit the version to 1063 and Click "FILE" then "Save" then Close
4. RIGHT-CLICK version.ini File then TICK the Read-Only box then Click Apply then OK.
5. Run CF LAUNCHER or patcher_cf2.exe
If you cannot change/edit the version.ini file and "Access Denied" pops-up.
1. Open CF FOLDER
2. FIND version.ini file
3. Right Click version.ini file then click PROPERTIES
4. Click Security Tab and Click Edit(Permission)
5. Tick Full Control and Click Apply.
6. Open version.ini file
7. Change 1062 to 1063 and Save
8. Right Click version.ini File then PROPERTIES
9. Tick Read Only then Click Apply then Ok.
10. Launch Crossfire.
