英文:
Wix V4 - CustomAction Condition only when updating
问题
问题细节：
我有一个在卸载时执行的操作，但在将产品更新到新版本时不执行。
我已经这样定义了UpgradeVersion：
Minimum="1.0.0" IncludeMinimum="yes"
Maximum="$(var.Version)" IncludeMaximum="no"/>
这是自定义操作及其条件：
<Custom Action="DOSTUFF" Before="RemoveFiles" Condition='(REMOVE="ALL") And (NOT PREVIOUSFOUND)'/>
尽管如此，当使用更高版本的.msi运行时，该操作仍然触发（例如：1.0.0 -> 1.0.1）。
我还尝试过像这样定义PREVIOUSFOUND属性：<Property Id="PREVIOUSFOUND" Secure="yes"></Property>，但无济于事。
我的期望：
我期望该操作仅在从控制面板“应用和功能”卸载时运行，而在将程序更新到更高版本时不运行。
英文:
Details of the problem:
I have an action that has to be executed when unistalling but not when updating the product to a new version.
I have defined the UpgradeVersion like this:
<UpgradeVersion OnlyDetect="no" Property="PREVIOUSFOUND"
Minimum="1.0.0" IncludeMinimum="yes"
Maximum="$(var.Version)" IncludeMaximum="no"/>
and this is the Custom action and its Condition:
<Custom Action="DOSTUFF" Before="RemoveFiles" Condition='(REMOVE="ALL") And (NOT PREVIOUSFOUND)'/>
Despite this, the action still fires when running the .msi with a higher version (e.g.: 1.0.0 -> 1.0.1).
I've also tried defining the PREVIOUSFOUND property like this: <Property Id="PREVIOUSFOUND" Secure="yes"></Property> to no avail.
What I was expecting:
I expected the action to run only when uninstalling from the Control Panel Apps & Features and not when updating the program to a higher version.

根据Stein的评论，我在此帖子中找到了解决方案。
所以我将我的条件更改为<Custom Action="DOSTUFF" Before="RemoveFiles" Condition='(REMOVE="ALL") And (NOT UPGRADINGPRODUCTCODE)'/>，现在CustomAction被正确触发。
英文:
As per Stein's comment, I found a solution in this post.
So I changed my condition to <Custom Action="DOSTUFF" Before="RemoveFiles" Condition='(REMOVE="ALL") And (NOT UPGRADINGPRODUCTCODE)'/> and now the CustomAction is triggered correctly.
