Windows Instructions:

1. Print these instructions now!! The most common reason people have problems installing the UMass Chime resources is that they skip over these simple instructions.
2. Updates only: If you are upgrading to a new version of a Chime resource previously installed and working, delete all files in the old folders (e.g. for Hemoglobin, delete all files in chime\hemoglob. (In order to avoid having to separate them out during upgrades, you should never put any files containing your personal work in these folders.)
3. If you have not downloaded some of these packages before, first create a new folder (directory) named chime, for example on your C: drive (c:\chime).
4. In your chime folder, create a new folder/subdirectory with the same name as the zipped filename of the resource you wish to download (without the trailing .exe, for example if you download antibody.exe, create folder c:\chime\antibody).
5. Download the .exe file into its new empty directory/folder of the same name. DO NOT LEAVE THE .EXE FILE ON YOUR DESKTOP! MOVE IT TO THE APPROPRIATE FOLDER. IF YOU ACCIDENTALLY RUN THE .EXE FILE ON YOUR DESKTOP, IT WILL MAKE A BIG MESS ON YOUR DESKTOP!
6. In Windows, open Windows Explorer and find the .exe file you have just downloaded. Make sure it is in the directory/folder matching its name. For example if you downloaded bilayers.exe, it must be in the directory/folder c:\chime\bilayers. If it is not there, move it there now.
7. Double click on the .exe file and it will unzip (decompress) itself. (If a DOS window remains open when this has finished, close the DOS window.) After unzipping, you may delete the .exe file if you wish.
8. Note: If and only if you are downloading the Noncovalent Bond Finder, or the Protein Morpher, you also need the package shared.exe. It must be in placed in a directory/folder named shared, e.g. c:\chime\shared. A directory/folder named for example "shared folder" or "shared.exe" will not work! Create the folder shared side by side with your other folder(s), e.g. c:\chime\morpher and c:\chime\shared. Download shared.exe into this folder and unzip it by double-clicking.
9. All UMass Chime resources run in Netscape. Some also run in Internet Explorer -- these are marked *Win-IE-Compatible* on the main Chime Resources page. Start an appropriate browser.
10. Netscape: Pull down the File menu, select Open Page, and use the Choose File button to find and open the file index.htm (not index.html) in the new folder containing the resource you have just unpacked. Bookmark it! In future, use this bookmark to start your downloaded UMass Chime resource. (You do not need to open or bookmark any file in the shared folder.)
11. Internet Explorer: (only if the resource is designated Win-IE-Compatible -- see above). Pull down the File menu, select Open, and use the Browse button to find and OK the file index.htm (not index.html) in the new folder containing the resource you have just unpacked. Bookmark it! In future, use this bookmark to start your downloaded UMass Chime resource. (You do not need to open or bookmark any file in the shared folder.)
12. After printing the above, you are ready to DOWNLOAD the .exe file(s).

Macintosh Instructions:

1. Print these instructions now!! The most common reason people have problems installing the UMass Chime resources is that they skip over these simple instructions.
2. Updates only: If you are upgrading to a new version of a Chime resource previously installed and working, delete all files in the old folders (e.g. for Hemoglobin, delete all files in Chime Resources:hemoglob. (In order to avoid having to separate them out during upgrades, you should never put any files containing your personal work in these folders.)
3. If you have not downloaded some of these packages before, first create a new folder named Chime Resources.
4. If you do not have a recent (updated 2000 or more recently) version of Aladdin Stuffit Expander freeware, update your version now. Version 5.5 or later works with the .exe files downloadable here.
5. Download the .exe file containing the desired UMass Chime Resource.
6. If Stuffit Expander does not automatically decompress the .exe file, drop the .exe file onto Stuffit Expander. This will create a folder named, for example, "shared.exe Folder". [This folder will contain many files (.htm, .spt, .js).]
7. Rename the unpacked folder to just the part of the name before the .exe. For example, rename "shared.exe Folder" to shared, and rename "antibody.exe Folder" to antibody. Your resources may fail to work if you don't rename the folders in this manner. The name of the shared folder is particularly critical. (You need the shared folder only if you are downloading the Noncovalent Bond Finder or the Protein Morpher.)
8. Drag the renamed folder(s) into the "Chime Resources" folder. It is critical that the "shared" folder be in the same "Chime Resources" folder which contains the folders for the resources which need it, namely "find-ncb" and "morpher".
9. In Netscape, select File, Open and double click on the file index.htm (not index.html) in the folder of the new resource. (Chime is not available for Macintosh Internet Explorer. You do not need to open any file in the shared folder.)
10. Bookmark it! In future, use this bookmark to start your downloaded UMass Chime resource.
11. After printing the above, you are ready to DOWNLOAD the .exe file(s).
