Upgrading

[yamakamyar]

Hi:

I would like to call an installscript function:

export prototype myCustomActionFunction(HWND);

1. only when patching
2. only when it is a minor upgrade
3. only when it is a major upgrade
4. only when it is an uninstall
5. only when it is an install
6. combo 4 + (1 or 2 or 3)

How can I do this? In script? On the property custom action sheets?

Thanks,
Yama

As a condition on the custom action (not in code):

• patching: PATCH
  
• minor upgrade: use same condition as SetupResume
  
• major upgrade: use "action property" from Upgrade table; by default ISACTIONPROP1
  
• uninstall: REMOVE="ALL" after InstallValidate
  
• first-time install: Not Installed
