从 WiX 中的 64 位 MSI package 写入 32 位目录的 hack

Question

Is there any solution to write files to 32-bit directories from 64-bit MSI package in WiX-toolset

Answer 1

As you all know that 64-bit MSI packages cannot write to 32-bit directories. so we need separate MSIs for 32-bit and 64-bit.

My solution:

I came up with hack to copy files to 32-bit directories from 64-bit MSI package:

        <!--"System64Folder"-->
        <Directory Id="System64Folder">
                <Component Id="text1_comp" Guid="PUTYOURGUIDHERE" Win64="yes">
                    <File Source=".\SetupFiles\textFile.txt" Id="textFile1" KeyPath="yes" />
                </Component>
        </Directory>
        <!--"System32Folder"-->
        <Directory Id="WindowsFolder">
            <Directory Id="SystemFolder_x86" Name="SysWOW64">
                <Component Id="text2_comp" Guid="PUTYOURGUIDHERE" Win64="yes">
                    <File Source=".\SetupFiles\textFile.txt" Id="textFile2" KeyPath="yes" />
                </Component>
            </Directory>
        </Directory>

As you can see, the idea is to reference the WindowsFolder then reference SysWOW64 . This way our file "textFile.txt" will copied to both System32 and SysWOW64 folders.
