Hi, all.

I know you're going to just shake your head at this, but here it is.

I create installers for one of many products that install onto a group of
roughly 14,000 systems at my employer. Some of these systems have drives
that are small by modern standards, and thanks to a weird partitioning
scheme, the drive with the Windows directory is seldom more than 30 - 40 GB.

I've just found out that, in order to get enough drive space to keep
running, our support team sometimes deletes the contents of the
windows\installer directory - the Windows Installer Cache.

In a bit of reading on the Microsoft site -
https://support.microsoft.com/en-us/kb/2667628 - this is something of a
fatal injury for the Windows Installer in terms of uninstall or repair of
already installed packages.

Despite that, nobody is going to reinstall Windows on these devices -
they're scattered around the country connected to slow DSL lines for the
most part, and nobody local is willing or able to do that.

I don't really care about the bigger problem, but I'm wondering if anyone
has any "thoughts about authoring packages that might have to install into
that mess, or might have to be used to upgrade an already installed package
whose cache contents got deleted. (Different ProductCode, same UpgradeCode.)

Thanks,

Walt
