Windows Installer返回不正确的错误代码 [英] Windows Installer returns incorrect Error Code

问题描述

大家好，

我正在使用windowds安装程序（* .MSI）设置项目来为我的Windows桌面模块创建MSI文件。

使用

Hi All,
I am using windowds installer (*.MSI) set-up project to create MSI file for my Windows Desktop Module.
The installation is done in silent mode (not using the installation wizard) using command like

Setup.msi /q /Lv "mylog.txt" 

每做一次更改在代码中，我创建了一个新的设置文件，其中包含更新的程序集号，设置版本号 - 也可以更新产品代码。

另外'检测较新的已安装版本'属性设置为True 。



我遇到了一个安装了设置号为1.1.115并仍然是用户试图安装设置号1.1.114的情况。使用上面的命令。



正如预期的安装失败，因为已经安装了较新版本，但它返回了错误代码，如下所示。

For every change made in the code , i create a new set-up file with updated assembly number, Set-up Version number- which updates product code as well.
Also 'Detect Newer Installed version' property is set to True.

I came across a case where set-up number 1.1.115 is installed and still user tries to install set-up number 1.1.114. using the above command.

As expected installation fails as newer version is already installed but it returned incorrect error code as below.

The install fails because of 
MSI (s) (64:08) [10:06:42:216]: Product: "Product name" -- Unable to install because a newer version of this product is already installed.

We are getting error 1603 and I am expecting 1638


ERROR_INSTALL_FAILURE    1603   Fatal error during installation.

I am expecting

ERROR_PRODUCT_VERSION    1638   Another version of this product is already 
                                installed. Installation of this version 
                                cannot continue. To configure or remove 
                                the existing version of this product, use 
                                Add/Remove Programs on the Control Panel.

我们总是得到错误代码1603而不是1638.



i用Google搜索但无法得出结论。



如果您以前遇到过这个问题，请告诉我们吗？

我必须在安装项目中做些什么更改才能获得正确的错误代码？



谢谢

We always get Error Code 1603 instead of 1638.

i did googled for it but could not come to a conclusion.

Experts please let me know if you have faced this issue before?
What changes do i have to make in setup project in order to get correct ERROR CODE?

Thanks

推荐答案

ERROR_PRODUCT_VERSION不是您错误的返回码看到 - 如果您尝试过度安装相同的产品代码安装，则会收到E..P..V错误



您可能会找到安装创建者你正在使用的是改变每个构建的产品代码



产品/包装/升级代码 [ ^ ]



（MSI只能升级，他们无法降级 - 我的存在感到难过）

ERROR_PRODUCT_VERSION is not the return code for the error you're seeing - you get the E..P..V error if you try to over-install the same 'productcode' install

you'll probably find the install creator you're using is changing productcode each build

Product/Package/Upgrade codes[^]

(MSI's can only upgrade, they cannot downgrade - bane of my existence)
