更改了 MSI 中的组件 GUID，这导致了问题
我正在开发一个产品的安装程序（当前版本 3）。在版本 1 和版本 2（已发布）之间，组件的 guid 发生了更改，但密钥路径和一切都保持不变（并且需要保持不变）。在版本 3 中，我需要进行更改以在安装顺序中稍后移动 RemoveExisitingProducts。然而，这暴露了一个新的错误，导致从版本 1 升级到版本 3 时，其 guid 更改的组件无法安装。我正在尝试找出解决此错误的方法。修复可以修复安装，但我不想修复。我认为可能需要某种破解来修复它，但我还没有成功。我尝试转到 HKLM/Microsoft/windows/currentversion/installer/user data/S-15-18/components/OLDPACKEDGUID 并在运行新安装程序之前将其删除，但这似乎会导致严重的问题，而且情况会更糟。
有人知道这个问题的解决方案吗，即使这是一个大黑客？ 谢谢
I am working on the installer for a product (currently version 3). Between versions 1 and 2 (already released), the guid of a component was changed, but the keypath adn everything stayed the same (and needs to stay the same still). In version 3, I need to make a change to move RemoveExisitingProducts later in the install sequence. However, this is exposing a new bug causing the component that had its guid changed to not be installed if upgrading from version 1 to version 3. I'm trying to figure out a way around this bug. Repairing fixes the installation but I'd rather not have to repair. I think it'll probably take some kind of hack to fix it, but I haven't been successful. I tried going to HKLM/Microsoft/windows/currentversion/installer/user data/S-15-18/components/OLDPACKEDGUID and deleting it before running the new installer, but that seems to cause terrible issues and be much worse.
anyone know a solution to this issue, even if it's a big hack?
Thanks

您可以尝试将
RemoveExistingProducts安排在序列的前面，以便在升级过程中，在安装新产品之前完全卸载以前的产品。另请看看这个 WiX 升级问题。并且
You can try to schedule
RemoveExistingProductsearlier in the sequence so that during upgrade the previous product is completely uninstalled before installing the new product.Also look at this WiX upgrade question. And another one may also be helpful.
