Hey @hyh6611 ,

There is an additional installer log in C:\Users\YOUR_USER\AppData\Local\Temp that is needed here to find out what is happening.

@Liryna Sorry dear devs, I searched my temp folder and I deleted everything that might be related, but when I install the version of Dokan Library 1.3.0.1000 Bundle again I still get a prompt, it tells I have a newer version on my computer, but I have uninstalled all versions of dokan

@hyh6611 Thanks for the logs. Do you remember which version 2 you installed exactly ?

[hyh6611]

@Liryna Hello, dear developer, I remember that the two versions I installed were 2.0.3.1000 and Dokan Library 1.3.0.1000 Bundle.

@Liryna Hello, I was wondering if my most advanced version was not uninstalled cleanly. But I searched many folders and found no residual files.

@js69 I am struggling to get the v2 installer to work properly with the v1. I probably missed to change some GUID but I am not sure if they should all be changed or some should stay fixed 😄 . Would you be able to take a look ?

Like uninstalling v2 when v1 is installed just do nothing on my Win 10 x64

Can't look at it in detail at the moment but generally: product code changes with every version, upgrade code should only ever change if it is a software completely independent of all previous versions (i.e. no automatic update from v1.x to v2.x). For us it means all upgrade codes (UpgradeCodeXyy and BundleUpgradeCode) for v2.x need to be set once and then never change until e.g. v3.x. The SetAssemblyVersion tool changes the product code in version.xml but will not touch the upgrade codes.
