Working with Projects
3. In the Project Location box, enter a new path or click Browse to find the appropriate location.
4. Click OK.
The default location for all new projects that you create with InstallShield is the one that you specified.
Although this folder is used for all new projects, any existing projects remain in the previous location.
GUID stands for Globally Unique Identifier. A GUID is 128 bits long, and the algorithm used to generate
a GUID guarantees each GUID to be unique. Because GUIDs are guaranteed to be unique, they can be
used to identify COM classes, Product Codes, and various other codes.
For example, after a product is installed, a key is created under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and is named
after the installation’s Product Code. At one time, this key was named after the Product Name. However,
this caused a potential conflict. If two installations were installed on the same machine, and both shared
the same Product Name, they would also share the same registry key. Because a GUID is now used, it
guarantees that this conflict does not occur.
An example GUID is {5D607F6A-AF48-4003-AFA8-69E019A4496F}. Any letters in a GUID must be in
uppercase.
GUIDs in Your Project
When you create an installation project, there are a number of different GUIDs that are relevant to your
project.
Table 2-3: GUIDs
