No reboot after 2.1.0 uninstallation

[dswiss-desktop-app]

Hi, we've noticed that uninstalling Dokan 2.1.0 does not ask for a reboot anymore - it still needs to be done manually to install it again, or to install a different version. Is it intentional ? To me it may lead to problems with upgrades in future.

Normally it should ask for restart if the installer wasn't able to remove the driver during uninstall. Usually it happens when the driver was used (mount a filesystem).

Hi @Liryna ,
I confirm this is an issue for dokan 2.1.0 (and 2.2.0 too). Reboot is not triggered when uninstalled.
I made some investigation on this issue and this is what I found.

My system specs:
Edition Windows 11 Pro
Version 23H2
Installed on ‎17/‎10/‎2022
OS build 22631.4037
Experience Windows Feature Experience Pack 1000.22700.1027.0

Processor 11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz 2.42 GHz

System type 64-bit operating system, x64-based processor

I used Dokan_x64.msi for 2.0.4 and 2.1.0.
I followed these steps being sure the registry does not contain any entries, and no leftovers from previous installations:

• run Dokan_x64.msi to install dokan
• immediately after, run it again to uninstall dokan

For 2.0.4: the restart is always prompted when the uninstaller ends. Here is the screenshot:

For 2.1.0 it never occur.

The registry for 2.0.4 at the end of the uninstallation (before restart):

On, the other end, once the uninstaller for 2.1.0 is ended (and no restart is prompted), if I try again to immediately install 2.1.0 it fails because a Windows reboot is still pending. These are the screenshots with the registry contents once the installer has failed:

See these links about why HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\ seems to be important in this context:

For me this is definitely something to be investigated further.
Regards.

Hi Liryna,

Thanks for the quick reply. Unfortunately that's not what we are experiencing. On all our Windows 11 machines (including a brand new virtual machine where there was no previous Dokan installation) the 2.1.0 uninstallation (we use the DokanSetup.exe bundle) does not trigger the restart, nor the pop-up asking for a restart. After that when we try to install any Dokan version, we get an error saying that there is a reboot pending. I am attaching the 2.1.0 uninstallation log followed by a failed 2.1.0 installation attempt. I have also attached a 2.0.4 uninstaller log where it asks for a restart at the end of the uninstallation.

The reboot was indeed gone when we switched to using dokanctl in the custom action to install the driver (previously we used wix api to install the driver with the inf but we now do it manually (dokanctl)).
I added a custom action that will detect whether reboot is needed. Does that looks alright ?

@Liryna Yes, it looks good.
