General CD Install Troubleshooting
If you are having problems getting the game to install or the game is asking for a CD5, you may want to try some of the following suggestions.
When changing CDs during the installation, let the drive spin-up and then stop. Then click OK and see if the installer recognizes the disc change. Do this for all the CDs that are requested.
Try checking for a firmware/BIOS update for your CD or DVD drive. We have had several reports of sucessfull installs of the game once a firmware update was applied. You will have to check with your CD/DVD drive manufacturer for this kind of update.
If for whatever reason you are unable to do a Recommended or Full install, but you can do a Minimum install, please read How to "fake" a larger install from a Minimum.
If you have multiple CD/DVD drives, only install from one and do not try to use all of your drives. For some reason, this is confusing InstallShield.
If you cannot do any install without getting some sort of error or crash and you have about 5 Gig of free hard drive space, you can try to copy all 4 CDs to your hard drive, then run the install from there. Please note, you must copy all 4 CDs to the same directory for the install to run. If you get prompted for the next CD, then you have not copied the files over properly, or you have missed some.
Try turning off DMA for your CD/DVD drive. For some people, this has allowed them to install. You can find this checkbox by going to your Control Panel, then to System, then to the Device Manager tab. Find your CD/DVD drive and bring up its Properties, then go to the Settings tab.
Try turning off your CD/DVD read-ahead. For some people, this has allowed them to install. You can find this slider by going to your Control Panel, then to System, then to the Performance tab. Down in the Advanced Settings frame, press the File System... button and move the slider all the way to the left. You may need to restart for this setting to take effect.
CRC errors while installing
CRC error occur when the installer compares the file it just copied to your hard drive to the source on the CD and finds that they are different. There are two possible causes:
Bad CDs. Take your copy of the game and try installing it on another computer. If you get CRC errors then you need to get your CDs exchanged for new ones.
Hardware issue. If you are able to install the game on another computer, you most likely have a hardware issue with your system. Refer to the General CD Install Troubleshooting above for other possible solutions.
How to "fake" a larger install from a Minimum install
Minimum to Recommended Install
1. Do a Minimum install.
2. Edit your "baldur.ini" file. Change the line "Install Type=1" to "Install Type=2"
3. Copy the following files from CD2 to your BG2 directory, where [cddrive] is the letter of your CD-ROM drive and [BG2] is the location of your BG2 install
[cddrive]\CD2\Data\CREAnim.bif ===> [BG2]\data\CREAnim.bif
[cddrive]\CD2\Data\CREAnim1.bif ===> [BG2]\data\CREAnim1.bif
[cddrive]\CD2\Data\GUIMosc.bif ===> [BG2]\data\GUIMosc.bif
[cddrive]\CD2\Data\MovHD0.bif ===> [BG2]\data\MovHD0.bif
[cddrive]\CD2\Data\NPCSoCD3.bif ===> [BG2]\data\NPCSoCD3.bif
[cddrive]\CD2\Data\NPCSound.bif ===> [BG2]\data\NPCSound.bif
4. Copy the following files from CD3 to your BG2 directory
[cddrive]\CD3\Data\CD3CreA2.bif ===> [BG2]\data\CD3CreA2.bif
[cddrive]\CD3\Data\CD3CreAn.bif ===> [BG2]\data\CD3CreAn.bif
[cddrive]\CD3\Data\CDCreAni.bif ===> [BG2]\data\CDCreAni.bif
5. Copy the following files from CD4 to your BG2 directory
[cddrive]\CD4\Data\CD4CreA2.bif ===> [BG2]\data\CD4CreA2.bif
[cddrive]\CD4\Data\CD4CreA3.bif ===> [BG2]\data\CD4CreA3.bif
[cddrive]\CD4\Data\CD4CreAn.bif ===> [BG2]\data\CD4CreAn.bif
You now have a Recommended install.
Minimum to Full Install
1. Do a Minimum install.
2. Edit your "baldur.ini" file. Change the line "Install Type=1" to "Install Type=3". Also, you will need to edit the [Alias] section. Make the following changes where [BG2] is the location of your BG2 install
[Alias]
HD0=[BG2]
CD1=[BG2]\CD1
CD2=[BG2]\CD2
CD3=[BG2]\CD3
CD4=[BG2]\CD4
3. Copy the following directories (and all their contents) from the BG2 CDs to your BG2 install folder, where [cddrive] is the letter of your CD-ROM drive and [BG2] is the location of your BG2 install
CD2
[cddrive]\CD2 ===> [BG2]\CD2
CD3
[cddrive]\CD3 ===> [BG2]\CD3
CD4
[cddrive]\CD4 ===> [BG2]\CD4
You now have a Full install.
But, after all that (!) what actually worked for me (and my sister!) when being prompted for CD5 (which it does if it cannot find a particular file during installation) was to copy all four disks to a newly created folder (just call it BG or something) then run the install from there.
1. Create a new file on your hard drive called BG (you will need approx 5 gigs of space to do this (you can then free up this space after by deleting the BG folder once your install has been successful))
2. Put CD1 into your CD Rom drive. Using windows explorer, select all files on CD1 and copy to your new BG folder.
3. Insert CD2 into your CD drive. Double click on your CD drive, you will see a file called CD2, copy this file to BG folder. Repeat for disks 3 and 4.
4. Check your BG folder, it should contain various files and folders, in particular CD2, CD3 and CD4 folders. If you double click on one of these three, you should see they contain one file (a data.cab file) and 2 sub folders called Data and Movies.
Run install from BG folder on hard drive.
I am sorry if this seems long winded or too much of an idiots guide, it is easy to get it wrong (I did!). The key thing to remember is do not create a folder called CD2, 3, or 4 in your BG directory - the copying from CDRom will do this.
If you are prompted for a disk a file has not been copied properly. Good luck...
