New function added to the internal SetupBuilder version. It will handle it automatically. This will be available in the next update.

Thanks again for your suggestion.

Perfect, thank you for the update!

No, you can change the GUID and the uninstaller will NOT lose this reference count.

Re: Best practice for removing an installed, registered DLL

I figured it out! Because v2 (update from v1) marked the file as shared DLL as well as in v1, the count was incremented to 2. If I manually increment the count to 3, and uninstall the application, the entry is then only 1. Awesome, SB8 keeps track of the amount of times the number is incremented!

Will changing the upgrade GUID or anything cause the uninstaller to lose this reference count?

Re: Best practice for removing an installed, registered DLL

Sorry for the confusion.

I thought calling regsvr32 -u decrements the reference count but I just found out it doesn't!

Either way, my files are still being deleted on uninstall even went reference count > 1. Would you like me to send installers? Do you need .sb8 files also?

Re: Best practice for removing an installed, registered DLL

BTW, an installer does not use "regsvr32 -u" because it calls the Windows API directly (Register as OCX checkbox).

Hello,

I am afraid I don't understand, sorry What does "regsvr32 -u" have to do with the SharedDll counter and with the deleted file(s)?

I think I went over file size limit. Here:

Re: Best practice for removing an installed, registered DLL

I must be doing something wrong. Please see attachment.

I am installing my COM dlls in %COMMONFILESIDIR%\MyCompany\Location\.

When I "regsvr32 -u" manually the count decrements by one, so its not happening inside COM code itself.

Re: Best practice for removing an installed, registered DLL

Hello,

Please see attached screenshots (Windows 10 Enterprise Edition x64, latest TP build). Two projects make use of the same shared DLL. After running both setups, the shared counter for the file SBKERNEL.DLL is "2". After uninstalling one project, the shared counter is "1" and the file is still there. If it is "0" then the uninstaller removes the registry key and the file.

Does this help?

Re: Best practice for removing an installed, registered DLL

That seemed to have worked great.

What I did notice is that if the reference count in the SharedDll key is >1, and I uninstall the application--remember Register as Shared File and Remove on Uninstall were both checked--the files still get removed from the INSTALLDIR.

Do I need to uncheck "Remove on Uninstall" and manually check the reference count in the script to see if its safe to delete the files? It would be nice if that automatically happened because adding cases for 120 files would get ugly.
