Just to be clear. On one customer’s computer the package cache folder only
contained that one MSI file (I asked him what was in that folder). The only
other “things” in the package cache were folders of that MSI file.
I would think that the MSI file and folders would get removed on rollback but
for some reason it was not.

Subject: Re: [WiX-devs] Windows 7 Professional - Package Cache and Encryption
It perplexes me a little bit how the .msi file would get encrypted but none of
the other files are. As pointed on in a different for of the thread, I could
maybe see how the "Package Cache" might inherit encryption from parent folders
and propagate down to all the payloads... but I'm not seeing how just the .msi
file gets marked encrypted. That is still a mystery to me. However, if you have
consistent repro we should try a couple things in burn and see if we can solve
the root issue.

I had a second customer where our burn installer failed on Windows 7
Professional x64. I had him go into the "Package Cache" folder and encryption
was not set on it and all subfolders but was set on the one remaining msi file.
I had him remove the encryption from the file and rerun the installer and it
then installed successfully. Must be a bug in rollback also because it left
one MSI there (I cache 3 in total). I guess good thing otherwise I wouldn't
have found the cause.
Has there been any problems with Visual Studio install for Windows 7
professional? If I've seen this twice Visual Studio team must have seen this
before. I tried reproducing this on my Windows 7 Ultimate x64 computer by
encrypting the package cache folder and then installing but it installed fine
(as you would expect).
Where is the encryption code located in the burn source code?
Maybe it should be changed to check MSI files before they are run from the
cache and decrypt them. What do you guys think?
