Okay guys, I tried everything, I saw another post about this but none of its guides worked.
so now i'll give u a precise action of what i did:
1. Inserted CD1 of Red alert into the DVD/CD drive.
2. Cancled the auto run and went into explore the disk.
in this stage there were to posts with too ways, one way was like:
Go To Setup95 Folder (i went to it) and right click on setup.exe that set the complitability mode to win95 (did so) than run the install from that file. here is the problem with that: when i run the installer from that file a DOS window opened and says that the installation could not find Setup.mix (wich is found to be in the folder Setup and not in Setup95) so i tried doing the same with the Setup.exe file in the Setup folder and the same error came.

now for the second guide,
I went to explore the disk and right clicked on Setup.exe that changed the complitability mode to windos 95 and runed the file. it was loading normally the wizard (windows is prepearing the install wizard wich will guide you throught the installation) and when it finished prepearing (100%) it gave me that error: Windows 5.1 Is Currectly Running. This version of Red Alert is a Windows 95 only product.

any ideas why isn't this working?

First put the RA CD on first CD/DVD drive.
1) On RA CD, there are folder named SETUP and there are dos version of the installer, install.exe. Launch it.




2) It'll start and then ask for sound card, I selected none.
3) Then it asks where to install. C:\WESTWOOD\RA
4) Files copied....
5) After install go to where you installed it.

6)
Download 1.08 patch. http://www.sharoma.com/ral/files/ra108usp.exe.

7) Copy the patch file ("ra108usp.exe") to your RA folder ("c:\westwood\redalert").
8) Doubleclick the patch file to start file extracting.
9) Now, on the folder there should be file named "patch.exe". Doubleclick it.
10) Wait while it patches RA. Dos screen will appear for while. Let it finish.
11) Now you have patched the game, create shortcut for file named "RA95.exe". Rightclick the shortcut and select Properties. Click Compatiblity tab. Apply following compatiblity settings to shortcut: Windows 95, 256 colors, 640x480, Disable themes and turn off advanced text services.
12) Done, launch the game by using this shortcut.

Agine, when i run the Install.exe file it says:
Unable to load the Setup.mix file from the CD-Rom

Edit:

I managed to install the game NORMALLY (not from the dos) but now when i click RA95.exe it says: The Procedure Point SMapLS_IP_EBP_12 could not be located in the dynamic link libary KERNEL32.dll

Edit2:

I managed to patch the game after i downloaded the patch file u gave and.. it works! u guys sure know ur job! i appriciate that.

im hoping somebody can help me with this problem whenever i click install or start the setup.exe an error occurs and a popup says "C:\WINDOWS\SYSTEM32\AUTOEXEC.NT. The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose 'Close' to terminate the application." ive seen a few other posts on other forums of people with this same problems but i havnt seen any posts on how to fix it. anyhelp would be appreciated

Start->Run:
c:\windows\system32\cmd.exe

Enter following two commands to the prompt:
copy c:\windows\repair\autoexec.nt c:\windows\system32\
and
copy c:\windows\repair\config.nt c:\windows\system32\

Answer yes, if asked to overwrite file.

Update your antimalware programs and do a scan.

Hey guys. I have the same problem, can't find setup.mix even when I click Install.exe in the setup folder. And it won't work either if I click Setup, no matter what I do, even if I use the compatibilty mode, still does the same thing. Can anyone help?

It ask for CD,
for your information, i dont have CDs and i install it from the files i download from Internet...

I've successfully install the game but just cant run without the CD.

any solution for this?

Buy the game. It's still being sold under the title Command and Conquer The First Decade.
