What do I have to do to fix the error "Failed to copy file needed for patch". It happened on the crossfire.exe file. Need Help.

Hello,

To fix the error “Failed to copy file needed for patch” that occurred with the crossfire.exe file, you can try the following steps:

Navigate to the Crossfire installation folder on your computer.

Search for the stuck .dll file by name within the installation folder.

Delete the problematic .dll file(s). This may prompt the system to regenerate the old ones and allow the patch to continue running.

If the issue persists, you might want to try running the selfupdate_cf.exe, patcher_cf.exe, and crossfire.exe files in that order, and if any pop-ups appear, close them before trying to run Crossfire again.

I hope the information may helps you. 

I have the same problem and tried everything you mentioned
