I tried to change a user defined property in a InstallScript, as below operation, but it cannot be changed after processing its InstallScript. 1) Add new property by Property Manager. Name: ETYPE Value: NULL 2) Write a simple InstallScript , in which I use MsiSetProperty function. #include "ifx.h" export prototype MyFunction(HWND); function MyFunction(hMSI) begin MsiSetProperty(ISMSI_HANDLE, "ETYPE", "HELLO"); end; 3) Insert this custom action(InstallScript) by Custom Action Wizard. Insert it in in Install UI Sequence. As I check its property in MSI debugger, it is not changed (NULL). Could someone point out my mistake, please ? Is it not possible by InstallScript ? or Is the function(MsiSetProperty) not correct ? or Is Sequence inserted not wrong ? Please help me. ... View more
