[bug] Installing new versions leaves old Installer on system

Post by jafin »

When I install new Versions of Duplicate Cleaner Pro 5, it leaves old versions of the installer in Add/Remove programs. There are NOT multiple copies of the executable on the system, and if I attempt to use one of the older uninstallers it will remove the latest version installed.

Confirmed.

I think it's going to be more like, assuming you've installed into the same install location, it will remove those parts applicable to the particular uninstall version.

So say you've installed 5.0.0.12 into c:\5.0.0.12 & then you install 5.0.0.4 (older) into that same location (c:\5.0.0.12), if you were to remove 5.0.0.4, you'll find that some files are left behind & those would be files attributable to 5.0.0.12 that did not have corresponding files in 5.0.0.4.

For instance, 12 includes the file, "Duplicate Cleaner 5 help.chm", that was not in 4, so the 4 uninstaller leaves that file behind.
(If you ran the 12 uninstaller, it would then remove that file.)

Thanks, yes I noticed this the other day. The MSI installer doesn't seem to consider it an update when using the last two digits. I've tried tweaking the versioning system and it's just cleaned up all the stray installer fragments (I had about 30). So, it should get cleaned up on the next release!
