Leftover cached MSI files
Posted 16 April 2002 - 12:42
Having read some newsgroup postings, some people are convinced they should be removed, others think on reboot, others have the same problem. My .Msi file is 16 meg and after numerous installs the C: drive fills up at an alarming rate.
Is this a bug with the Windows Installer service, are there programs to remove them.

I have just been doing a bit of testing and it appears that Windows Installer removes the cached files upon the next reboot!!!
If this is the case, our product does not need rebooting during install or uninstall so, installing the product populates
HKLM\Software\Microsoft\Windows\CurrentVersion\Installer\Userdata\S-x-x-x\Products\Number\LocalPackage with the randomly generated C:\winnt\installer\blah.msi.
Now if the product is uninstalled and reinstalled this LocalPackage value will be overwritten with the latest randomly named cached msi file, leave the previous one orphaned upon reboot. With 10 installs/uninstalls without reboot the C:\winnt\installer folder is filling up.

Ok, I see your point but In my opinion it is a weak mechanism.
