C++ compilers

I have downloaded Bloodshed Dev4.0 and the other C++ compilers, but when I try to open them, I get the message "document's format is invalid or not supported."
What does this mean and how do I fix it? Thanks.

That could be many things, take a screen shot and post it.
I'm thinking it has to do with the fact that those compilers try to associate .c and .cpp files with them, if multiple registry entries were made they may be conflicting.

The compiler executable(s), the compressed file(s), or the associations like Waldo2k2 mentioned?

A possiblity is downloading in ascii mode instead of binary mode. Some download managers will do that.

If the compressed files have a .tar, .lzh or such and you're using Winzip, then you'll need a program that decompresses that format in addition to Winzip.

What OS are you using, and what compression utility are you using?

Thanks for responding, but I'm really new at computers. I want to learn C++, so I'm trying to download the Bloodshed Dev4.0 C++ compiler since it is supposed to be one of the easier ones to set up.
So Waldo2k2, what do you mean by taking a screen shot and post it? How is this done? Also ronin, I didn't quite understand what was said. How do you download in ascii mode? What is an OS and compression utility? Can you state what you said again for someone without knowledge of computer jargon. I still don't really understand why I'm getting the message, "document's format is invalid or not supported" when I try to open the C++ compiler. Thanks.

My guess is that they are zip files and you don't have winzip. please post the extension of the file format. How to do this:

Right click the downloaded file and select properties. When the properties window opens, press the "print screen" key on the keyboard, which is located after the F12 button at the top.

Then open windows paint by going to start---programs---accessories---paint.

Go to edit--paste or press control+V. You will see a picture of your desktop and the dialog appear. Go to file---save and save it as a jpeg by selecting JPG from the drop menu under "file name".

Then come here, click "post reply", and at the bottom, under the reply box, you will see "Attach file". Click choose and select the image you just saved and click ok. Then click submit reply.

Hello Ride-or-Die. I couldn't save it as a jpeg because the drop menu under "file name" only had bmp, dib. So it is saved as a "24-bit Bitmap(.bmp,.dib). Also, after clicking "post reply", I do not see "Attach file" under the reply box. I do see a forum rules box that says, " You may not post attachments." Am I missing something? How do I attach this file? Thanks.

its ok to attach a file.

look right above submit you will see a little txt box with choose next to it.

Hello Ride-or-Die. I tried clicking "post reply" again and got a different screen. So I was able to attach the file. I hope you can see the image okay.

u need winzip, www.winzip.com
