Fix by r.2.d.2_PL
Warcraft 3 uses microsoft Visual C++ 8.0 runtime libraries. If the libraries are not installed in the system – w3 gives warning about the system misconfiguration.
You can download microsoft libraries from here. Don’t worry – digitally signed by microsoft. Taken from VC5 package and legal to distribute freely. After the installation Warcraft3 will run normally.
Step 2: If it didn’t worked **
** you should do it after you tried previous method but it didn’t worked
If installation of previous file didn’t worked and WC3 still can’t be run you need new version of microsoft installer (download page – directly from microsoft). Select your OS language from list, then go bottom and you’ll find something likeWindowsInstaller-KB893803-v2-x86.exe
Download this, install and then run the fix by r2.d.2_PL again.
