WIX如何知道它是否安装32位或64位软件?(How does WIX know if it's installing 32 or 64 Bit software?)

我有一个WIX安装程序,它可以创建一些注册表项并安装一些软件。 我不使用package -elements属性“Platform”,也不使用candle.exe开关。

我想出了为什么它将软件复制到C:\Program Files (x86)\Vendor\Product而不是C:\Program Files\Vendor\Product :显然,使用ProgramFilesFolder自动重定向到32位软件路径:

<Directory Id="TARGETDIR" Name="SourceDir">
    <Directory Id="ProgramFilesFolder"> <!-- 64 Bit Folder would be "ProgramFiles64Folder" -->
        <Directory Id="Vendor" Name="Vendor">
            <Directory Id="INSTALLDIR" Name="Product">

但是我找不到类似的注册表项。 为什么WIX将注册表项从Software\Vendor\Product重定向到Software\WOW6432Node\Vendor\Product ? 为什么WIX认为我不安装32位软件?

示例:此代码在Software\WOW6432Node\Apache Software Foundation\Procrun 2.0\...创建注册表项

<RegistryKey Root="HKLM"
    Key="Software\Apache Software Foundation\Procrun 2.0\$(var.serviceName)\Parameters"
    ForceDeleteOnUninstall="yes">
    <RegistryValue Key="Java" Name="Classpath" Type="string" Value="[JettyHomeDirectory]start.jar"/>

I have a WIX installer that creates some registry keys and installs some software. I do not use the package-elements attribute "Platform" and I also do not use the -arch switch of candle.exe.

I figured out why it copies the software to C:\Program Files (x86)\Vendor\Product instead of C:\Program Files\Vendor\Product: Apparently, the use of ProgramFilesFolder automatically redirects to the 32-bit software path:

<Directory Id="TARGETDIR" Name="SourceDir">
    <Directory Id="ProgramFilesFolder"> <!-- 64 Bit Folder would be "ProgramFiles64Folder" -->
        <Directory Id="Vendor" Name="Vendor">
            <Directory Id="INSTALLDIR" Name="Product">

But I cannot find something similar for registry keys. Why does WIX redirect registry keys from Software\Vendor\Product to Software\WOW6432Node\Vendor\Product? Why does WIX think I install 32 bit software when I don't?

Example: This code creates registry keys in Software\WOW6432Node\Apache Software Foundation\Procrun 2.0\...

<RegistryKey Root="HKLM"
    Key="Software\Apache Software Foundation\Procrun 2.0\$(var.serviceName)\Parameters"
    ForceDeleteOnUninstall="yes">
    <RegistryValue Key="Java" Name="Classpath" Type="string" Value="[JettyHomeDirectory]start.jar"/>

最满意答案

您应该返回值,而不是在函数中调用printf

return sum;

要么

return average;

无论如何,你的函数都期望float返回值。 您的编译器应该已经警告过您。 无论如何,你应该能够像这样调用它(假设你在main声明了相关的变量):

sum = array_sum(myNumbers,size);
average = array_average(myNumbers,size);
printf("sum = %5.2f", sum);
printf("avg = %5.2f", average);

显然, array_average函数正在执行与array_sum相同的工作而不添加任何其他值,因此您应该通过调用array_sum而不是复制代码来计算总和。


Instead of calling printf in your functions, you should return the value:

return sum;

or

return average;

Both your functions expect a float return value anyway. Your compiler should have warned you about this. Anyway, you should be able to call it like this (assuming you have the relevant variables declared in main):

sum = array_sum(myNumbers,size);
average = array_average(myNumbers,size);
printf("sum = %5.2f", sum);
printf("avg = %5.2f", average);

Obviously, the array_average function is doing a lot of the same work as array_sum without adding any additional value, so you should calculate the sum by calling array_sum instead of duplicating the code.
