Installshield-合并模块-基于用户对话框输入的动态目标目录

Question

I am trying to set the override the destination directory of the merge module as described here. I set the destination directory to [BIN]. BIN is public property. At compile time the value of [BIN] is C:\\Program Files (x86)\\CompanyName\\ProductName.

Based on the user input in a custom dialog, this property is updated to C:\\Program Files (x86)\\CompanyName\\UserInputName\\ProductName.

All the DLL files from the merge module are copied into the compile-time value of [BIN] - C:\\Program Files (x86)\\CompanyName\\ProductName. For some reason, the dynamic value is ignored in this case.

Can someone tell me what could be going wrong?

I am using Install Shield Version 2010 Professional Edition, Project Type is Basic MSI Project

Answer 1

Merge Modules add a GUID to every primary key to prevent merge collisions. So the BIN identifier actually turns into BIN.G_U_I_D when used in a Merge Module.

To resolve this issue, Merge Modules are designed to be "retargetable" .

Answer 2

I have posted the same question on InstallShield forum, the conclusion there was it is not supported by InstallShield to change destination directory of an MSM file during run time.

A workaround suggested is to have a custom action 'Set Directory'.

Here are the steps:

1. In the Redistributable view, right click on the MSM file -> Properties -> Destination -> set to [MSM_DEST_STATIC_DIR].
2. Create a custom action of type'Set Directory', with Directory Name - MSM_DEST_STATIC_DIR, Directory Value - [MSD_DEST_DIR_DYNAMIC_VALUE]
3. After getting the user input from the dialog, first, update the MSD_DEST_DIR_DYNAMIC_VALUE, then execute the custom action created in step 2.

While doing this I also realized that it is not possible to update the IISROOTFOLDER based on the dynamic user input. I followed the same procedure with the custom action to update the IISROOTFOLDER.
