InstallShield 2012 升级程序制作时的product code 和upgrade code

For differentproducts:

Eg. CATS 5 and CATS 6 are different products, because you want them to co-exist in one computer, and be able to upgrade them seperately.

The difference will be:

1.       Product name is different

2.       GeneralInfo:

Product Code:  should be changed

Upgrade Code:  should be changed

 

For Upgrade:eg.:  4.5.0à4.5.1

1.       theproduct Name stays the same, version number is upgrade

2.       GeneralInfo:

Product Code:  should be different

Upgrade Code: should be the same

 

Here are some explainations:

 

1.      Product Name willeffect the folder where the Application will be installed in the computer.Eg.:  Carefusion/CATS 4.5 or  Carefusion/CATS 4.6

2.      Product code willbe used to check if the product is installed or not. If the product code is thesame, you will get: Another version exists..  

 Some official infosays for minor upgrade you don’t need to change the product code, but in mycase, I have to change the product code.  See moreexplaination1 , explaination2

3.      Upgrade code is used to identidy a family of products. If theupgrade code is the same, after install 4.6, you are not able to install 4.5anymore. It will say, a newer version is already installed on this computer.
